Fixes #71. - Fix compilation of extended comprehensions. Fixes #72. - Fix computation of float array access bounds. - Fix aggregation of clauses (could sometimes ignore the negative literals). Version 2.0.10 ============== Bug fixes: - Fix a bug in the optimiser that could lead to undefined variables in the generated FlatZinc. Fixes #70. Version 2.0.9 ============= Bug fixes: - Need to take return type into account when copying functions to output model. Fixes #55. - Evaluate calls that result in arrays using eval_arraylit. Fixes #57. - Move inverse function to its own library file, so that it remains available when a solver provides an alternative for the inverse predicate. - Optimisation phase now recursively checks constraints when elements in an array become fixed. - Fix CMakeLists file to work for paths that contain spaces. - Distinguish between infix operators and regular functions in the generated html documentation. Fixes #61. - Made parser more robust against incorrect code. - Fix increment/decrement operators for IntVals and make all operations throw correct overflow exceptions. - Fix automatic type coercion for variables declared in let expressions. - Fix a crash when printing some error messages. - Fix compute_div_bounds builtin to return correct result for a division by zero. - Fix optimisation of Boolean constraints to use pointer equality instead of structural equality (same expression can occur multiple times in the FlatZinc). - Only optimise constraints that have not been removed yet. - Fix declaration of functional version of bin_packing_load. Fixes #64. - Set type of arrays returned from polymorphic functions. Fixes #65. - Fix parsing of quoted unary operator calls. - Only compute set functions when bounds are valid. Fixes #66. - Compute proper bounds for if-then-else expressions. - Report error when no reified version of a constraint is available. Fixes #67. - Fix type checking of annotations on binary operators. - Keep annotations when rewriting linear constraints and remove is_defined_var annotations from fixed variables. Fixes #69. Changes: - Integer, Boolean and float literals are now cached to achieve better memory performance for some models. - Improve performance of parsing integer literals. - Improve handling of clause constraints. - Add source files of MiniZinc specification to the repository. - Limit maximum array size to enable better error messages. - Add implied_constraint predicate as a synonym for redundant_constraint. Version 2.0.8 ============= Bug fixes: - Fix incorrect negation of some reified comparisons. - Make lb/ub functions work in more cases. - Fix several bugs in the optimisation phase (could lead to incorrect FlatZinc and crashes). - Fix a problem with reverse mapper functions when the result of the reverse mapper can be fixed to a constant. Version 2.0.7 ============= Changes: - Improved propagation of Boolean constants in the optimisation phase. This should result in far fewer aliases and improves simplification of conjunctions, disjunctions and clauses. - Add special case handling for integer division by 1. Bug fixes: - Fix FlatZinc generator phase, need to turn all array literal arguments into 1-based single dimensional arrays. - Fix compilation of if-then-else expressions with var conditions (which didn't implement proper partiality/totality semantics). Fixes #42. - Provide correct bounds for weak opt var arithmetic. Fixes #51. - Need to be able to handle unflattened annotations. Fixes #53. - Fix generation of output model (needs to ignore items that have been removed previously). - Add missing lb(var set of int) builtin. Fixes #47. - Check that var set declarations have a finite element type. Fixes #46. - Fix translation context for binary operators on arrays. - Need to access IntVal::infinity as a function, otherwise depending on linker etc it may become 0 in some cases. Fixes #40. - Change pretty printer to use one less digit when printing float literals. This fixes #41 (or at least provides a workaround), but some double constants may still be rounded incorrectly when pretty printing and reading them back in. The real fix will be to output hex float literals (coming soon). - Distinguish between generalised comprehensions (iterating over sets) and iterating over arrays. Fixes compilation of comprehensions where iteration over an array is combined with var where clauses. Fixes #45. - Fix bug in creation of output model where sometimes chains of variable definitions could lead to crashes. - Avoi creating mutually recursive definitions in some corner cases, which could cause the compiler to run into infinite loops. - Don't copy vardecl items to output model that are already there. Fixes #44. - Remove domain from array declarations in FlatZinc (avoids problems with domains where holes need to be removed and when there are infinities in the domains) - Fix flattening of equality operator between non-opt and opt vars - Check that model contains a single solve and output item during type checking (previously, multiple output items were not detected and resulted in incorrect .ozn files). - Fix flattening of xor (arguments need to be in mixed context). - Use is_fixed in cumulative definition. - Fix bug where a par right hand side of a variable mentioned in the output would cause a crash. - Fix variable dependency tracking during rewriting in the optimisation phase. Could previously lead to variables being removed that are still required. Fixes #54. Version 2.0.6 ============= Changes: - Add parser support for hexadecimal floating point constants. Bug fixes: - Fix bounds computation for some calls (abs, int_times). - Fix flattening of some array declarations (when right hand side is an identifier). - Add four missing GC locks (could lead to incorrect garbage collection). - Compact output model only after optimisation phase (could lead to incorrect items being removed from output model). Version 2.0.5 ============= Changes: - Improve the standard decomposition for the cumulative constraint. - Better handling of binary operators during type checking and flattening, can sometimes avoid stack overflows (e.g. for large conjunctions). - Make ++ operator left associative (avoid stack overflows in the parser). - Add ::domain annotations to linear constraints generated from multi-dimensional element constraints. - Greatly improved linearisation library. Bug fixes: - Fix recursive function calls that contain let expressions. - Fix compilation of comprehensions inside parametric functions. - Fix a memory leak in solns2out. - Fix a problem in the evaluation of binary operators. - Fix a bug in the flattening of array literals. - Fix a bug that would crash the parser on certain syntax errors in let expressions. Version 2.0.4 ============= Changes: - Models can now be read from standard input (using the "-" or "--input-from-stdin" command line options). Thanks to Sebastian Kosch. - Improved handling of bool2int during FlatZinc generation. Bug fixes: - Fix unification of aliased variables which could sometimes result in variables being removed although had a constraining right hand side. - Fix evaluation of set comprehensions. - Fix command line flag --no-output-ozn - Fix performance problem when evaluating array expressions inside lets. - Fix flattening of bool_xor redefinitions. - Fix partial evaluation of some array access expressions with var indexes. - Fix definition of geost constraint. - User-defined functions are now copied correctly into the output model if they are referenced in the output item. - Set comprehensions are fully evaluated. Version 2.0.3 ============= (Internal release that did not contain some essential fixes) Version 2.0.2 ============= Changes: - The optimiser now removes simple domain constraints from the FlatZinc - The compiler now checks for integer overflows in all built-in operations - Report an error when the FlatZinc or ozn file cannot be opened for writing - Add support for 3d array literals (e.g. [| |1,2|3,4|,|5,6|7,8| |] ) - Add show2d and show3d functions for formatting array output - Add row/col functions for variable arrays (github issue #2) - Introduce builtins for creating random distributions - Add reverse library function - Postpone flattening of some reified constraints - Slightly improved compilation of partial function calls when it can be inferred at compile time that their result is undefined - Allow functions with empty argument lists to be declared as function int: foo(); instead of just function int: foo; - Improve error reporting, in particular for errors in comprehensions - Enable expressions a..b where a and b are integer variables - Add redundant_constraint and symmetry_breaking_constraint builtins, these can be rewritten by solver libraries to allow e.g. local search solvers to ignore redundant constraints. - Improve flattening of predicates that simply return their arguments (makes the redundant_constraint and symmetry_breaking_constraint predicates work in more situations). - Replace command line option --only-range-domains by optional boolean value so that solver libraries can set the flag directly in their redefinitions file. - Stop flattening immediately when a model has been found to contain an inconsistency. - Improve flattening of array access expressions, in particular for nested array accesses that can be combined into a single element constraint - Add command line option -s or --statistics to print statistics about the generated FlatZinc - Improve bounds computation for if-then-else expressions - Clause arguments are compiled in positive and negative contexts instead of mixed. That means that predicates that introduce free variables can now be used in the positive part of a clause. Bug fixes: - Fix simplification of linear expressions, negative coefficients could sometimes result in incorrect bounds - Fix bounds computation for unary minus operator - Add missing par set comparison builtins - Fix bounds computation for extended comprehension syntax - Fix a bug in the garbage collector that could sometimes lead to premature deletion of expressions - Fix bounds computation for set difference - Fix duplication of some arrays in the FlatZinc (github issue #3) - Fix bounds inference for variables bound to empty sets (github bug #3) - Fix bug in error reporting function, which would sometimes not report the entire call stack - Fix the generation of fresh variable names for generator expressions - Fix subtype check to allow empty arrays as subtype of arrays of sets - Fix crash when using assert/2 - Fix bug when function used in output referred to par variable - Fix bug in type checker, the detection of cyclic definitions was not correct and could lead to stack overflows - Fix parser to accept expressions with two consecutive array accesses (like x[3][4], which are valid MiniZinc if x is an array of sets) - Fix error reporting when an evaluation error occurs within a comprehension generator - Report type error on some ambiguous function calls - Report type error on var sets with element type other than int - Report type error when trying to coerce a var set into an array - Report error when calling function with a value that is outside the declared parameter bounds - Fix arg_sort builtin to implement the correct semantics - Fix sort_by builtin to sort in non-decreasing order, and work with floats - Fix bug in type checker, now automatic coercions in functions defined with type variables (like the comparison operators) work correctly - Check that index sets match for arrays assigned in let expressions - Fix bug in bounds inference for integer expressions with annotations - Fix propagation of defines_var annotation to be pushed through calls - Fix parser to accept empty 2d and 3d array literals - Fix flattening to remove defines_var annotations with par argument, e.g. defines_var(2), which could be introduced by the optimisation pass - Fix output model creation for variables that have been redefined, and remove more unused variables from the FlatZinc. - Fix bug in the garbage collector that could result in function items not being kept alive in rare cases. Version 2.0.1 ============= Major bugs and changes: - Fix optimisation phase, which was previously incorrectly removing variables - Add support for trigonometric functions (built-ins were missing in 2.0.0) and pow (var versions were missing) - Fix equality operator on par arrays - All expressions in output model are now made par - Improve bounds computation for float variables - Fix translation of functions that need automatic coercion of their return value - Fix the array_lb and array_ub builtins, which would return incorrect bounds in some cases Minor bugs and changes: - Add space between "array" and "[" in the pretty printer, to be compatible with 1.6 output - Output all par declarations before the var declarations in FlatZinc - Fix parser, which could sometimes crash on invalid input - Improve efficiency of bounds computation on some float expressions - Add special case handling for division by 1 - Add missing float_times definition to the flatzinc builtins - Use correct version of var_dom for float variables - Output information about which files are included in verbose mode - Only compute bounds for "then" expressions if the "if" is not fixed to false Version 2.0.0 ============= MiniZinc 2.0 contains many new features and is based on a complete rewrite of the MiniZinc-to-FlatZinc compiler. If you are currently using the previous version 1.6, the new tools can be used as drop-in replacements. The generated FlatZinc is compatible with version 1.6, so all FlatZinc solvers should work without changes. ** MiniZinc language changes ** - MiniZinc now supports user-defined functions. Details have been published in the paper "MiniZinc with Functions". Both functions and predicates can be recursive. - MiniZinc now supports option types. Details have been published in the paper "Modelling with Option Types in MiniZinc". - Let expressions have been generalised. They can now contain constraint items in addition to variable declarations. - Array index sets can be declared using arbitrary set expressions as long as they evaluate to contiguous ranges. - The if-then-else expression has been generalised to allow the condition to be a var bool expression (instead of only par bool). - Array and set comprehensions as well as generator calls can now iterate over variables and use var bool where conditions. - Any bool expression can now automatically coerce to an int expression, likewise for int and float. This means that you don't have to write bool2int or int2float in your models any more. - Equality constraints can now be posted between array expressions. - Arbitrary expressions can now be included ("interpolated") into strings, using the syntax "some text \(e) some more text", where e is any expression. It is the same as writing "some text "++show(e)++" some more text". ** New built-in functions ** Array functions: array1d, arrayXd, row, col, has_index, has_element, sort_by, sort, arg_sort, arg_min, arg_max ** New global constraints ** - arg_max, arg_min - arg_sort - k-dimensional diffn - disjunctive - geost - knapsack - network_flow - regular with NFAs - symmetric all different - optional scheduling constraints: alternative, span, disjunctive, cumulative - functional versions of many global constraints ** New tool chain ** - There are a few new builtins that solvers can reimplement, these are listed in the redefinitions-2.0 file. - Include items use a different method for finding included files. Paths are now interpreted as relative to the file that has the include item. That way, the mzn2fzn compiler can be called from a different working directory. - A new tool, mzn2doc, can produce html output from the documentation comments. The MiniZinc distribution contains the documentation for global constraints and builtins generated directly from the library source code. libminizinc-2.0.11/include/0000755000175000017500000000000012646030173014165 5ustar kaolkaollibminizinc-2.0.11/include/minizinc/0000755000175000017500000000000012646030173016005 5ustar kaolkaollibminizinc-2.0.11/include/minizinc/model.hh0000644000175000017500000002337012646030173017433 0ustar kaolkaol/* -*- mode: C++; c-basic-offset: 2; indent-tabs-mode: nil -*- */ /* * Main authors: * Guido Tack */ /* This Source Code Form is subject to the terms of the Mozilla Public * License, v. 2.0.

Compiler options: SAFEINT_WARN_64BIT_PORTABILITY - this re-enables various warnings that happen when /Wp64 is used. Enabling this option is not recommended. NEEDS_INT_DEFINED - if your compiler does not support __int8, __int16, __int32 and __int64, you can enable this. SAFEINT_ASSERT_ON_EXCEPTION - it is often easier to stop on an assert and figure out a problem than to try and figure out how you landed in the catch block. SafeIntDefaultExceptionHandler - if you'd like to replace the exception handlers SafeInt provides, define your replacement and define this. Note - two built in (Windows-specific) options exist: - SAFEINT_FAILFAST - bypasses all exception handlers, exits the app with an exception - SAFEINT_RAISE_EXCEPTION - throws Win32 exceptions, which can be caught SAFEINT_DISALLOW_UNSIGNED_NEGATION - Invoking the unary negation operator creates warnings, but if you'd like it to completely fail to compile, define this. ANSI_CONVERSIONS - This changes the class to use default comparison behavior, which may be unsafe. Enabling this option is not recommended. SAFEINT_DISABLE_BINARY_ASSERT - binary AND, OR or XOR operations on mixed size types can produce unexpected results. If you do this, the default is to assert. Set this if you prefer not to assert under these conditions. SIZE_T_CAST_NEEDED - some compilers complain if there is not a cast to size_t, others complain if there is one. This lets you not have your compiler complain. SAFEINT_DISABLE_SHIFT_ASSERT - Set this option if you don't want to assert when shifting more bits than the type has. Enabling this option is not recommended. ************************************************************************************************************************************/ /* * The SafeInt class is designed to have as low an overhead as possible * while still ensuring that all integer operations are conducted safely. * Nearly every operator has been overloaded, with a very few exceptions. * * A usability-safety trade-off has been made to help ensure safety. This * requires that every operation return either a SafeInt or a bool. If we * allowed an operator to return a base integer type T, then the following * can happen: * * char i = SafeInt(32) * 2 + SafeInt(16) * 4; * * The * operators take precedence, get overloaded, return a char, and then * you have: * * char i = (char)64 + (char)64; //overflow! * * This situation would mean that safety would depend on usage, which isn't * acceptable. * * One key operator that is missing is an implicit cast to type T. The reason for * this is that if there is an implicit cast operator, then we end up with * an ambiguous compile-time precedence. Because of this amiguity, there * are two methods that are provided: * * Casting operators for every native integer type * Version 3 note - it now compiles correctly for size_t without warnings * * SafeInt::Ptr() - returns the address of the internal integer * Note - the '&' (address of) operator has been overloaded and returns * the address of the internal integer. * * The SafeInt class should be used in any circumstances where ensuring * integrity of the calculations is more important than performance. See Performance * Notes below for additional information. * * Many of the conditionals will optimize out or be inlined for a release * build (especially with /Ox), but it does have significantly more overhead, * especially for signed numbers. If you do not _require_ negative numbers, use * unsigned integer types - certain types of problems cannot occur, and this class * performs most efficiently. * * Here's an example of when the class should ideally be used - * * void* AllocateMemForStructs(int StructSize, int HowMany) * { * SafeInt s(StructSize); * * s *= HowMany; * * return malloc(s); * * } * * Here's when it should NOT be used: * * void foo() * { * int i; * * for(i = 0; i < 0xffff; i++) * .... * } * * Error handling - a SafeInt class will throw exceptions if something * objectionable happens. The exceptions are SafeIntException classes, * which contain an enum as a code. * * Typical usage might be: * * bool foo() * { * SafeInt s; //note that s == 0 unless set * * try{ * s *= 23; * .... * } * catch(SafeIntException err) * { * //handle errors here * } * } * * Update for 3.0 - the exception class is now a template parameter. * You can replace the exception class with any exception class you like. This is accomplished by: * 1) Create a class that has the following interface: * template <> class YourSafeIntExceptionHandler < YourException > { public: static __declspec(noreturn) void __stdcall SafeIntOnOverflow() { throw YourException( YourSafeIntArithmeticOverflowError ); } static __declspec(noreturn) void __stdcall SafeIntOnDivZero() { throw YourException( YourSafeIntDivideByZeroError ); } }; * * Note that you don't have to throw C++ exceptions, you can throw Win32 exceptions, or do * anything you like, just don't return from the call back into the code. * * 2) Either explicitly declare SafeInts like so: * SafeInt< int, YourSafeIntExceptionHandler > si; * or * #define SafeIntDefaultExceptionHandler YourSafeIntExceptionHandler * * Performance: * * Due to the highly nested nature of this class, you can expect relatively poor * performance in unoptimized code. In tests of optimized code vs. correct inline checks * in native code, this class has been found to take approximately 8% more CPU time (this varies), * most of which is due to exception handling. Solutions: * * 1) Compile optimized code - /Ox is best, /O2 also performs well. Interestingly, /O1 * (optimize for size) does not work as well. * 2) If that 8% hit is really a serious problem, walk through the code and inline the * exact same checks as the class uses. * 3) Some operations are more difficult than others - avoid using signed integers, and if * possible keep them all the same size. 64-bit integers are also expensive. Mixing * different integer sizes and types may prove expensive. Be aware that literals are * actually ints. For best performance, cast literals to the type desired. * * * Performance update * The current version of SafeInt uses template specialization to force the compiler to invoke only the * operator implementation needed for any given pair of types. This will dramatically improve the perf * of debug builds. * * 3.0 update - not only have we maintained the specialization, there were some cases that were overly complex, * and using some additional cases (e.g. signed __int64 and unsigned __int64) resulted in some simplification. * Additionally, there was a lot of work done to better optimize the 64-bit multiplication. * * Binary Operators * * All of the binary operators have certain assumptions built into the class design. * This is to ensure correctness. Notes on each class of operator follow: * * Arithmetic Operators (*,/,+,-,%) * There are three possible variants: * SafeInt< T, E > op SafeInt< T, E > * SafeInt< T, E > op U * U op SafeInt< T, E > * * The SafeInt< T, E > op SafeInt< U, E > variant is explicitly not supported, and if you try to do * this the compiler with throw the following error: * * error C2593: 'operator *' is ambiguous * * This is because the arithmetic operators are required to return a SafeInt of some type. * The compiler cannot know whether you'd prefer to get a type T or a type U returned. If * you need to do this, you need to extract the value contained within one of the two using * the casting operator. For example: * * SafeInt< T, E > t, result; * SafeInt< U, E > u; * * result = t * (U)u; * * Comparison Operators * Because each of these operators return type bool, mixing SafeInts of differing types is * allowed. * * Shift Operators * Shift operators always return the type on the left hand side of the operator. Mixed type * operations are allowed because the return type is always known. * * Boolean Operators * Like comparison operators, these overloads always return type bool, and mixed-type SafeInts * are allowed. Additionally, specific overloads exist for type bool on both sides of the * operator. * * Binary Operators * Mixed-type operations are discouraged, however some provision has been made in order to * enable things like: * * SafeInt c = 2; * * if(c & 0x02) * ... * * The "0x02" is actually an int, and it needs to work. * In the case of binary operations on integers smaller than 32-bit, or of mixed type, corner * cases do exist where you could get unexpected results. In any case where SafeInt returns a different * result than the underlying operator, it will call assert(). You should examine your code and cast things * properly so that you are not programming with side effects. * * Documented issues: * * This header compiles correctly at /W4 using VC++ 8 (Version 14.00.50727.42) and later. * As of this writing, I believe it will also work for VC 7.1, but not for VC 7.0 or below. * If you need a version that will work with lower level compilers, try version 1.0.7. None * of them work with Visual C++ 6, and gcc didn't work very well, either, though this hasn't * been tried recently. * * It is strongly recommended that any code doing integer manipulation be compiled at /W4 * - there are a number of warnings which pertain to integer manipulation enabled that are * not enabled at /W3 (default for VC++) * * Perf note - postfix operators are slightly more costly than prefix operators. * Unless you're actually assigning it to something, ++SafeInt is less expensive than SafeInt++ * * The comparison operator behavior in this class varies from the ANSI definition, which is * arguably broken. As an example, consider the following: * * unsigned int l = 0xffffffff; * char c = -1; * * if(c == l) * printf("Why is -1 equal to 4 billion???\n"); * * The problem here is that c gets cast to an int, now has a value of 0xffffffff, and then gets * cast again to an unsigned int, losing the true value. This behavior is despite the fact that * an __int64 exists, and the following code will yield a different (and intuitively correct) * answer: * * if((__int64)c == (__int64)l)) * printf("Why is -1 equal to 4 billion???\n"); * else * printf("Why doesn't the compiler upcast to 64-bits when needed?\n"); * * Note that combinations with smaller integers won't display the problem - if you * changed "unsigned int" above to "unsigned short", you'd get the right answer. * * If you prefer to retain the ANSI standard behavior insert * #define ANSI_CONVERSIONS * into your source. Behavior differences occur in the following cases: * 8, 16, and 32-bit signed int, unsigned 32-bit int * any signed int, unsigned 64-bit int * Note - the signed int must be negative to show the problem * * * Revision history: * * Oct 12, 2003 - Created * Author - David LeBlanc - dleblanc@microsoft.com * * Oct 27, 2003 - fixed numerous items pointed out by michmarc and bdawson * Dec 28, 2003 - 1.0 * added support for mixed-type operations * thanks to vikramh * also fixed broken __int64 multiplication section * added extended support for mixed-type operations where possible * Jan 28, 2004 - 1.0.1 * changed WCHAR to wchar_t * fixed a construct in two mixed-type assignment overloads that was * not compiling on some compilers * Also changed name of private method to comply with standards on * reserved names * Thanks to Niels Dekker for the input * Feb 12, 2004 - 1.0.2 * Minor changes to remove dependency on Windows headers * Consistently used __int16, __int32 and __int64 to ensure * portability * May 10, 2004 - 1.0.3 * Corrected bug in one case of GreaterThan * July 22, 2004 - 1.0.4 * Tightened logic in addition check (saving 2 instructions) * Pulled error handler out into function to enable user-defined replacement * Made internal type of SafeIntException an enum (as per Niels' suggestion) * Added casts for base integer types (as per Scott Meyers' suggestion) * Updated usage information - see important new perf notes. * Cleaned up several const issues (more thanks to Niels) * * Oct 1, 2004 - 1.0.5 * Added support for SEH exceptions instead of C++ exceptions - Win32 only * Made handlers for DIV0 and overflows individually overridable * Commented out the destructor - major perf gains here * Added cast operator for type long, since long != __int32 * Corrected a couple of missing const modifiers * Fixed broken >= and <= operators for type U op SafeInt< T, E > * Nov 5, 2004 - 1.0.6 * Implemented new logic in binary operators to resolve issues with * implicit casts * Fixed casting operator because char != signed char * Defined __int32 as int instead of long * Removed unsafe SafeInt::Value method * Re-implemented casting operator as a result of removing Value method * Dec 1, 2004 - 1.0.7 * Implemented specialized operators for pointer arithmetic * Created overloads for cases of U op= SafeInt. What you do with U * after that may be dangerous. * Fixed bug in corner case of MixedSizeModulus * Fixed bug in MixedSizeMultiply and MixedSizeDivision with input of 0 * Added throw() decorations * * Apr 12, 2005 - 2.0 * Extensive revisions to leverage template specialization. * April, 2007 Extensive revisions for version 3.0 * Nov 22, 2009 Forked from MS internal code * Changes needed to support gcc compiler - many thanks to Niels Dekker * for determining not just the issues, but also suggesting fixes. * Also updating some of the header internals to be the same as the upcoming Visual Studio version. * * Jan 16, 2010 64-bit gcc has long == __int64, which means that many of the existing 64-bit * templates are over-specialized. This forces a redefinition of all the 64-bit * multiplication routines to use pointers instead of references for return * values. Also, let's use some intrinsics for x64 Microsoft compiler to * reduce code size, and hopefully improve efficiency. * * June 21, 2014 Better support for clang, higher warning levels supported for all 3 primary supported compilers (Visual Studio, clang, gcc). Also started to converge the code base such that the public CodePlex version will be a drop-in replacement for the Visual Studio version. * Note about code style - throughout this class, casts will be written using C-style (T), * not C++ style static_cast< T >. This is because the class is nearly always dealing with integer * types, and in this case static_cast and a C cast are equivalent. Given the large number of casts, * the code is a little more readable this way. In the event a cast is needed where static_cast couldn't * be substituted, we'll use the new templatized cast to make it explicit what the operation is doing. * ************************************************************************************************************ * Version 3.0 changes: * * 1) The exception type thrown is now replacable, and you can throw your own exception types. This should help * those using well-developed exception classes. * 2) The 64-bit multiplication code has had a lot of perf work done, and should be faster than 2.0. * 3) There is now limited floating point support. You can initialize a SafeInt with a floating point type, * and you can cast it out (or assign) to a float as well. * 4) There is now an Align method. I noticed people use this a lot, and rarely check errors, so now you have one. * * Another major improvement is the addition of external functions - if you just want to check an operation, this can now happen: * All of the following can be invoked without dealing with creating a class, or managing exceptions. This is especially handy * for 64-bit porting, since SafeCast compiles away for a 32-bit cast from size_t to unsigned long, but checks it for 64-bit. * * inline bool SafeCast( const T From, U& To ) throw() * inline bool SafeEquals( const T t, const U u ) throw() * inline bool SafeNotEquals( const T t, const U u ) throw() * inline bool SafeGreaterThan( const T t, const U u ) throw() * inline bool SafeGreaterThanEquals( const T t, const U u ) throw() * inline bool SafeLessThan( const T t, const U u ) throw() * inline bool SafeLessThanEquals( const T t, const U u ) throw() * inline bool SafeModulus( const T& t, const U& u, T& result ) throw() * inline bool SafeMultiply( T t, U u, T& result ) throw() * inline bool SafeDivide( T t, U u, T& result ) throw() * inline bool SafeAdd( T t, U u, T& result ) throw() * inline bool SafeSubtract( T t, U u, T& result ) throw() * */ //use these if the compiler does not support _intXX #ifdef NEEDS_INT_DEFINED #define __int8 char #define __int16 short #define __int32 int #define __int64 long long #endif #if defined VISUAL_STUDIO_SAFEINT_COMPAT namespace msl { namespace utilities { #endif // catch these to handle errors // Currently implemented code values: // ERROR_ARITHMETIC_OVERFLOW // EXCEPTION_INT_DIVIDE_BY_ZERO enum SafeIntError { SafeIntNoError = 0, SafeIntArithmeticOverflow, SafeIntDivideByZero }; #if defined VISUAL_STUDIO_SAFEINT_COMPAT } // utilities } // msl #endif /* * Error handler classes * Using classes to deal with exceptions is going to allow the most * flexibility, and we can mix different error handlers in the same project * or even the same file.

This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4). 2.4. Subsequent Licenses No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3). 2.5. Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License. 2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents. 2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.

Versions of the License --------------------------- 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number. 10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4.

\pagebreak \tableofcontents \pagebreak %===========================================================================% \section{Introduction} %===========================================================================% This document defines MiniZinc, a language for modelling constraint satisfaction and optimisation problems. MiniZinc is a high-level, typed, mostly first-order, functional, modelling language. It provides: \begin{itemize} \item mathematical notation-like syntax (automatic coercions, overloading, iteration, sets, arrays); \item expressive constraints (finite domain, set, linear arithmetic, integer); \item support for different kinds of problems (satisfaction, explicit optimisation); \item separation of data from model; %\item high-level data structures and data encapsulation (sets, % arrays, tuples, records, enumerated types, constrained type-insts); \item extensibility (user-defined functions and predicates); \item reliability (type checking, instantiation checking, assertions); \item solver-independent modelling; \item simple, declarative semantics. \end{itemize} MiniZinc is similar to OPL and moves closer to CLP languages such as ECLiPSe. This document has the following structure. Section~\ref{Syntax Notation} introduces the syntax notation used throughout the specification. Section~\ref{Overview} provides a high-level overview of MiniZinc models. Section~\ref{Syntax Overview} covers syntax basics. Section~\ref{High-level Model Structure} covers high-level structure: items, multi-file models, namespaces, and scopes. Section~\ref{Types} introduces types and type-insts.

It is also available as a whole in Appendix~\ref{Grammar}. The output grammar also includes some details of the use of whitespace. The following conventions are used: \begin{itemize} \item A newline character or CRLF sequence is written \nl. \item A sequence of space characters of length $n$ is written \spc{$n$}, e.g., \spc{2}. \end{itemize} %===========================================================================% \section{Overview of a Model} \label{Overview} %===========================================================================% %---------------------------------------------------------------------------% %---------------------------------------------------------------------------% \CommonTwoConceptualParts{MiniZinc} {The model and data may be separated, or the data may be ``hard-wired'' into the model.} There are two broad classes of problems: satisfaction and optimisation. In satisfaction problems all solutions are considered equally good, whereas in optimisation problems the solutions are ordered according to an objective and the aim is to find a solution whose objective is optimal. Section~\ref{Solve Items} specifies how the class of problem is chosen. %---------------------------------------------------------------------------% \subsection{Evaluation Phases} %---------------------------------------------------------------------------% %\pjs{Remove the 3 evaluation phases, make it two!} A MiniZinc model instance is evaluated in two distinct phases. \begin{enumerate} \item Instance-time: static checking of the model instance. \item Run-time: evaluation of the instance (i.e.~constraint solving). \end{enumerate} % The model instance may not compile due to a problem with the model and/or data, detected at instance-time. This could be caused by a syntax error, a type-inst error, the use of an unsupported feature or operation, etc. In this case the outcome of evaluation is a static error; this must be reported prior to run-time. The form of output for static errors is implementation-dependent, although such output should be easily recognisable as a static error. An implementation may produce warnings during all evaluation phases. For example, an implementation may be able to determine that unsatisfiable constraints exist prior to run-time, and the resulting warning given to the user may be more helpful than if the unsatisfiability is detected at run-time. An implementation must produce a warning if the objective for an optimisation problem is unbounded. %---------------------------------------------------------------------------% \subsection{Run-time Outcomes} \label{Run-time Outcomes} %---------------------------------------------------------------------------% Assuming there are no static errors, the output from the run-time phase has the following abstract form: \begin{productions} \RuleOutput \end{productions} If a solution occurs in the output then it must be feasible. For optimisation problems, each solution must be strictly better than any preceding solution. If there are no solutions in the output, the outcome must indicate that there are no solutions. If the search is complete the output may state this after the solutions. The absence of the completness message indicates that the search is incomplete. Any warnings produced during run-time must be summarised after the statement of completeness. In particular, if there were any warnings at all during run-time then the summary must indicate this fact. The implementation may produce text in any format after the warnings. For example, it may print a summary of benchmarking statistics or resources used. %---------------------------------------------------------------------------% \subsection{Output} \label{Output} %---------------------------------------------------------------------------% % \pjs{Needs a total reworking for MiniZinc!} Implementations must be capable of producing output of content type `application/x-zinc-output', which is described below and also in Appendix~\ref{Content-types}. Implementations may also produce output in alternative formats. Any output should conform to the abstract format from the previous section and must have the semantics described there. Content type `application/x-zinc-output' extends the syntax from the previous section as follows: \begin{productions} \RuleSolution \end{productions} \noindent The solution text for each solution must be as described in Section~\ref{Output Items}. A newline must be appended if the solution text does not end with a newline. \Rationale{This allows solutions to be extracted from output without necessarily knowing how the solutions are formatted.} Solutions end with a sequence of ten dashes followed by a newline. \begin{productions} \RuleOutcomeStrings \end{productions} \noindent The completness result is printed on a separate line. \Rationale{The strings are designed to clearly indicate the end of the solutions.} \begin{productions} \RuleComplete \end{productions} \noindent If the search is complete, a statement corresponding to the outcome is printed. For an outcome of no solutions the statement is that the model instance is unsatisfiable, for an outcome of no more solutions the statement is that the solution set is complete, and for an outcome of no better solutions the statement is that the last solution is optimal. \Rationale{These are the logical implications of a search being complete.} \begin{productions} \RuleWarnings \\ \\ \RuleMessage \end{productions} \noindent If the search is incomplete, one or more messages describing reasons for incompleteness may be printed. Likewise, if any warnings occurred during search they are repeated after the completeness message. Both kinds of message should have lines that start with \texttt{\%} so they are recognized as comments by post-processing. \Rationale{This allows individual messages to be easily recognised.} For example, the following may be output for an optimisation problem: \begin{verbatim} =====UNSATISFIABLE===== % trentin.fzn:4: warning: model inconsistency detected before search. \end{verbatim} \noindent Note that, as in this case, an unbounded objective is not regarded as a source of incompleteness. %===========================================================================% \section{Syntax Overview} \label{Syntax Overview} %===========================================================================% \CommonCharacterSetAndComments{MiniZinc} %---------------------------------------------------------------------------% \subsection{Identifiers} \label{Identifiers} %---------------------------------------------------------------------------% Identifiers have the following syntax: \begin{productions} \RuleIdent \end{productions} For example: \begin{verbatim} my_name_2 MyName2 \end{verbatim} A number of keywords are reserved and cannot be used as identifiers. The keywords are: \reservedKeywords{} A number of identifiers are used for built-ins; see Section~\ref{builtins} for details. %===========================================================================% \section{High-level Model Structure} \label{High-level Model Structure} %===========================================================================% %---------------------------------------------------------------------------% \subsection{Items} %---------------------------------------------------------------------------% A MiniZinc model consists of multiple \emph{items}: \begin{productions} \RuleModel \end{productions} Items can occur in any order; identifiers need not be declared before they are used. Items have the following top-level syntax: \begin{productions} \RuleItem \end{productions} %Type-inst synonym items and enumerated type items define new types. Include items provide a way of combining multiple files into a single instance. This allows a model to be split into multiple files (Section~\ref{Include Items}). Variable declaration items introduce new global variables and possibly bind them to a value (Section~\ref{Declarations}). Assignment items bind values to global variables (Section~\ref{Assignments}). Constraint items describe model constraints (Section~\ref{Constraint Items}). Solve items are the ``starting point'' of a model, and specify exactly what kind of solution is being looked for: plain satisfaction, or the minimization/maximization of an expression. Each model must have exactly one solve item (Section~\ref{Solve Items}). Output items are used for nicely presenting the result of a model execution (Section~\ref{Output Items}). %\emph{Note:} models to be converted to FlatZinc should use the built-in %{\tt is\_output} annotation on variables rather than an output item. %If an output item is provided, then the corresponding FlatZinc model %should have output annotations placed on the variables appearing in the %original output item. Predicate items, test items (which are just a special type of predicate) and function items introduce new user-defined predicates and functions which can be called in expressions (Section~\ref{preds and fns}). Predicates, functions, and built-in operators are described collectively as \emph{operations}. Annotation items augment the \texttt{ann} type, values of which can specify non-declarative and/or solver-specific information in a model. %---------------------------------------------------------------------------% \subsection{Model Instance Files} \label{Model Instance Files} %---------------------------------------------------------------------------% MiniZinc models can be constructed from multiple files using include items (see Section~\ref{Include Items}). MiniZinc has no module system as such; all the included files are simply concatenated and processed as a whole, exactly as if they had all been part of a single file. \Rationale{We have not found much need for one so far. If bigger models become common and the single global namespace becomes a problem, this should be reconsidered.} Each model may be paired with one or more data files. Data files are more restricted than model files. They may only contain variable assignments (see Section~\ref{Assignments}). Data files may not include calls to user-defined operations. Models do not contain the names of data files; doing so would fix the data file used by the model and defeat the purpose of allowing separate data files. Instead, an implementation must allow one or more data files to be combined with a model for evaluation via a mechanism such as the command-line. %An implementation should allow a model to be checked with and without its %instance data. When checking a model without data, all global variables %with fixed type-insts need not be assigned. When checking a model with data, all global variables with fixed type-insts must be assigned, unless they are not used (in which case they can be removed from the model without effect). A data file can only be checked for static errors in conjunction with a model, since the model contains the declarations that include the types of the variables assigned in the data file. A single data file may be shared between multiple models, so long as the definitions are compatible with all the models. %---------------------------------------------------------------------------% \subsection{Namespaces} \label{Namespaces} %---------------------------------------------------------------------------% All names declared at the top-level belong to a single namespace. It includes the following names. \begin{enumerate} \item All global variable names. \item All function and predicate names, both built-in and user-defined. %\item All user-defined type and type-inst names (type-inst synonyms and % enumerated types). %\item All enum case names. \item All annotation names. \end{enumerate} Because multi-file MiniZinc models are composed via concatenation (Section~\ref{Model Instance Files}), all files share this top-level namespace. Therefore a variable \texttt{v} declared in one model file could not be declared with a different type in a different file, for example. MiniZinc supports overloading of built-in and user-defined operations. %MiniZinc has two kinds of local namespace: each record and (non-flat) enum %has its own local namespace for field names. This means distinct %records and (non-flat) enums can use the same field names. All names %in these local namespaces co-exist without conflict with identical names in %the top-level namespace---in any situation, which namespace applies can %always be determined from context. %---------------------------------------------------------------------------% \subsection{Scopes} \label{Scopes} %---------------------------------------------------------------------------% Within the top-level namespace, there are several kinds of local scope that introduce local names: \begin{itemize} \item Comprehension expressions (Section~\ref{Set Comprehensions}). \item Let expressions (Section~\ref{Let Expressions}). \item Function and predicate argument lists and bodies (Section~\ref{preds and fns}). %\item Type-inst constraints (Section~\ref{Arbitrarily Constrained % Type-insts}). \end{itemize} The listed sections specify these scopes in more detail. In each case, any names declared in the local scope overshadow identical global names. %===========================================================================% \section{Types and Type-insts} \label{Types} %===========================================================================% MiniZinc provides four scalar built-in types: Booleans, integers, floats, and strings; several compound built-in types: sets, multi-dimensional arrays; %with arbitrary index types, tuples, and records; and three kinds of %user-defined annotation types: type-inst synonyms, enumerated types, and \texttt{ann}, %a user-extensible type that represents annotations. and the user extensible annotation type \texttt{ann}. %Zinc also allows %type-inst variables in certain places, and has some very limited %higher-order types. \CommonInstantiationTypeInstDescription{} %Zinc also supports \emph{constrained type-insts}, which are type-insts %with an additional expression that constrains their possible values. We begin by discussing some properties that apply to every type. We then introduce instantiations in more detail. We then cover each type individually, giving: an overview of the type and its possible instantiations, the syntax for its type-insts, whether it is a finite type (and if so, its domain), whether it is varifiable, the ordering and equality operations, whether its variables must be initialised at instance-time, and whether it can be involved in automatic coercions. %We conclude by describing Zinc's constrained type-insts. %-----------------------------------------------------------------------------% \subsection{Properties of Types} %-----------------------------------------------------------------------------% The following list introduces some general properties of MiniZinc types. \begin{itemize} \item Currently all types are monotypes. % Recursive types are not allowed. In the future we may allow types which are polymorphic in other types and also the associated constraints. \item We distinguish types which are \emph{finite types}. In MiniZinc, finite types include Booleans, %flat enums, types defined via set expression type-insts such as range types (see Section~\ref{Set Expression Type-insts}), as well as sets and arrays, %tuples, records and non-flat enums composed of finite types. Types that are not finite types are unconstrained integers, unconstrained floats, unconstrained strings, and \texttt{ann}. Finite types are relevant to sets (Section~\ref{Sets}) and array indices (Section~\ref{Arrays}). Every finite type has a \emph{domain}, which is a set value that holds all the possible values represented by the type. \item Every first-order type (this excludes \texttt{ann}) has a built-in total order and a built-in equality; \texttt{>}, \texttt{<}, \texttt{==}/\texttt{=}, \texttt{!=}, \texttt{<=} and \texttt{>=} comparison operators can be applied to any pair of values of the same type. \Rationale{This facilitates the specification of symmetry breaking and of polymorphic predicates and functions.} Note that, as in most languages, using equality on floats or types that contain floats is generally not reliable due to their inexact representation. An implementation may choose to warn about the use of equality with floats or types that contain floats. %\item Higher-order types are used in very limited ways. They % can only be used with the built-in functions \texttt{foldl} and % \texttt{foldr}, which both take a function as their first argument. \end{itemize} %---------------------------------------------------------------------------% \subsection{Instantiations} \label{Instantiations} %---------------------------------------------------------------------------% \CommonInstantiationsDescription{MiniZinc} %% %There are also intermediate instantiations for some compound types---they %can have a fixed size but may contain unfixed elements. In MiniZinc decision variables can have the following types: Booleans, integers, floats, and sets of integers. %, and flat enums. %Tuples, arrays, records, non-flat %enums Arrays and \texttt{ann} can contain decision variables. %---------------------------------------------------------------------------% \subsection{Type-insts} \label{Type-insts} %---------------------------------------------------------------------------% \CommonTypeInstDescription{} MiniZinc allows coercions between some types as well. Some type-insts can be \emph{varified}, i.e.~made unfixed at the top-level. For example, \texttt{par int} is varified to \texttt{var int}. We write this \varify{\texttt{par int}}{\texttt{var int}}. Type-insts that are varifiable include the type-insts of the types that can be decision variables (Booleans, integers, floats, sets). %, enumerated types), and also tuples and records, %if their constituent elements can be varified. Varification is relevant to %type-inst synonyms and array accesses. %---------------------------------------------------------------------------% \subsection{Type-inst Expressions Overview} \label{Type-inst Expressions Overview} %---------------------------------------------------------------------------% This section partly describes how to write type-insts in MiniZinc models. Further details are given for each type as they are described in the following sections. A type-inst expression specifies a type-inst. \resolvedcomment{zs}{ I think the debacle with declaration syntax in C has shown that putting non-type things in type expressions is a bad idea. }{ Since they're now type-inst declarations, hopefully that will avoid the problems seen with C. } Type-inst expressions may include type-inst constraints. Type-inst expressions appear in variable declarations (Section~\ref{Declarations}), user-defined operation items (Section~\ref{preds and fns}).%, and type-inst synonyms %(Section~\ref{Type-inst Synonym Items}). Type-inst expressions have this syntax: \begin{productions} \RuleTIExpr \\ \RuleBaseTIExpr \\ \RuleVarPar \\ \RuleBaseTIExprTail \end{productions} %The first alternative is for arbitrarily constrained type-insts, which are %described in Section~\ref{Arbitrarily Constrained Type-insts}. % Base type-inst expressions have the % following syntax: % \begin{productions} % \RuleBaseTIExpr \\ % \RuleVarPar \\ % \RuleBaseTIExprTail % \end{productions} (The final alternative, for range types, uses the numeric-specific \nt{num-expr} non-terminal, defined in Section~\ref{Expressions Overview}, rather than the \nt{expr} non-terminal. If this were not the case, the rule would never match because the `\texttt{..}' operator would always be matched by the first \nt{expr}.) This fully covers the type-inst expressions for scalar types. The compound type-inst expression syntax is covered in more detail in Section~\ref{Built-in Compound Types}. %Type-inst variable syntax is %described in more detail in Section~\ref{Type-inst Variables}. %The constrained type-inst expressions are covered in more %detail in Section~\ref{Constrained Type-insts}. The \texttt{par} and \texttt{var} keywords (or lack of them) determine the instantiation. The \texttt{par} annotation can be omitted; the following two type-inst expressions are equivalent: \begin{verbatim} par int int \end{verbatim} \Rationale{The use of the explicit \texttt{var} keyword allows an implementation to check that all parameters are initialised in the model or the instance. It also clearly documents which variables are parameters, and allows more precise type-inst checking.} A type-inst is fixed if it does not contain \texttt{var} or \texttt{any}, with the exception of \texttt{ann}. Note that several type-inst expressions that are syntactically expressible represent illegal type-insts. For example, although the grammar allows \texttt{var} in front of all these base type-inst expression tails, it is a type-inst error to have \texttt{var} in the front of a string or array %, tuple, record, or type-inst variable type-inst expression. %-----------------------------------------------------------------------------% \subsection{Built-in Scalar Types and Type-insts} \label{Built-in Scalar Types} %-----------------------------------------------------------------------------% %---------------------------------------------------------------------------% \subsubsection{Booleans} %---------------------------------------------------------------------------% \TyOverview Booleans represent truthhood or falsity. \Rationale{Boolean values are not represented by integers. Booleans can be explicit converted to integers with the \texttt{bool2int} function, which makes the user's intent clear.} \TyInsts Booleans can be fixed or unfixed. \TySyntax Fixed Booleans are written \texttt{bool} or \texttt{par bool}. Unfixed Booleans are written as \texttt{var bool}. \TyFiniteType Yes. The domain of a Boolean is \texttt{\{false, true\}}. \TyVarifiable \varify{\texttt{par bool}}{\texttt{var bool}}, \varify{\texttt{var bool}}{\texttt{var bool}}. \TyOrdering The value \texttt{false} is considered smaller than \texttt{true}. \TyInit A fixed Boolean variable must be initialised at instance-time; an unfixed Boolean variable need not be. \TyCoercions \coerce{\texttt{par bool}}{\texttt{var bool}}. Also Booleans can be automatically coerced to integers; see Section~\ref{Integers}. % [this was relevant when operators like '<' were treated as % left-associative. Now that they are treated as non-associative, "0 < x < 10" % is a syntax error] %Booleans are not automatically coercible to 0-1 integers. %\begin{RationaleEnv} %This could be useful, but it is also dangerous. In particular, a user might %mean to write this: %\begin{verbatim} % constraint 0 < x /\ x < 10; %\end{verbatim} %but instead write this: %\begin{verbatim} % constraint 0 < x < 10; %\end{verbatim} %This would be parsed and implicitly coerced like this: %\begin{verbatim} % constraint coerce(bool, int, 0 < x) < 10; %\end{verbatim} %which always succeeds. Given that Zinc is quite high-level and %mathematical, it would be very easy for a user to assume that they can write %\texttt{0 < x < 10} and end up with a very subtle defect in their model. %Furthermore, the \texttt{bool2int} built-in function lets a user explicitly %coerce Booleans to integers easily. %\end{RationaleEnv} %---------------------------------------------------------------------------% \subsubsection{Integers} \label{Integers} %---------------------------------------------------------------------------% \TyOverview \CommonIntegersOverview{} \TyInsts Integers can be fixed or unfixed. \TySyntax Fixed integers are written \texttt{int} or \texttt{par int}. Unfixed integers are written as \texttt{var int}. \TyFiniteType Not unless constrained by a set expression (see Section~\ref{Set Expression Type-insts}). \TyVarifiable \varify{\texttt{par int}}{\texttt{var int}}, \varify{\texttt{var int}}{\texttt{var int}}. \TyOrdering The ordering on integers is the standard one. \TyInit A fixed integer variable must be initialised at instance-time; an unfixed integer variable need not be. \TyCoercions \coerce{\texttt{par int}}{\texttt{var int}}, \coerce{\texttt{par bool}}{\texttt{par int}}, \coerce{\texttt{par bool}}{\texttt{var int}}, \coerce{\texttt{var bool}}{\texttt{var int}}. Also, integers can be automatically coerced to floats; see Section~\ref{Floats}. %---------------------------------------------------------------------------% \subsubsection{Floats} \label{Floats} %---------------------------------------------------------------------------% \TyOverview \CommonFloatsOverview{} \TyInsts Floats can be fixed or unfixed. \TySyntax Fixed floats are written \texttt{float} or \texttt{par float}. Unfixed floats are written as \texttt{var float}. \TyFiniteType Not unless constrained by a set expression (see Section~\ref{Set Expression Type-insts}). \TyVarifiable \varify{\texttt{par float}}{\texttt{var float}}, \varify{\texttt{var float}}{\texttt{var float}}. \TyOrdering The ordering on floats is the standard one. \TyInit A fixed float variable must be initialised at instance-time; an unfixed float variable need not be. \TyCoercions \coerce{\texttt{par int}}{\texttt{par float}}, \coerce{\texttt{par int}}{\texttt{var float}}, \coerce{\texttt{var int}}{\texttt{var float}}, \coerce{\texttt{par float}}{\texttt{var float}}. %---------------------------------------------------------------------------% \subsubsection{Strings} %---------------------------------------------------------------------------% \TyOverview Strings are primitive, i.e.~they are not lists of characters. String expressions are used in assertions, output items and annotations, and string literals are used in include items. \TyInsts Strings must be fixed. \TySyntax Fixed strings are written \texttt{string} or \texttt{par string}. \TyFiniteType Not unless constrained by a set expression (see Section~\ref{Set Expression Type-insts}). \TyVarifiable No. \TyOrdering Strings are ordered lexicographically using the underlying character codes. \TyInit A string variable (which can only be fixed) must be initialised at instance-time. \TyCoercions None automatic. However, any non-string value can be manually converted to a string using the built-in \texttt{show} function or using string interpolation (see Section~\ref{String Interpolation Expressions}). %---------------------------------------------------------------------------% \subsection{Built-in Compound Types and Type-insts} \label{Built-in Compound Types} %---------------------------------------------------------------------------% %---------------------------------------------------------------------------% \subsubsection{Sets} \label{Sets} %---------------------------------------------------------------------------% \TyOverview A set is a collection with no duplicates. \TyInsts The type-inst of a set's elements must be fixed. \Rationale{This is because current solvers are not powerful enough to handle sets containing decision variables.} Sets may contain any type, and may be fixed or unfixed. If a set is unfixed, its elements must be finite, unless it occurs in one of the following contexts: \begin{itemize} \item the argument of a predicate, function or annotation. \item the declaration of a variable or let local variable with an assigned value. \end{itemize} \TySyntax A set base type-inst expression tail has this syntax: \begin{productions} \RuleSetTIExprTail \end{productions} Some example set type-inst expressions: \begin{verbatim} set of int var set of bool \end{verbatim} \TyFiniteType Yes, if the set elements are finite types. Otherwise, no. The domain of a set type that is a finite type is the powerset of the domain of its element type. For example, the domain of \texttt{set of 1..2} is \texttt{powerset(1..2)}, which is \verb+{{}, {1}, {1,2}, {2}}+. \TyVarifiable \varify{\texttt{par set of TI}}{\texttt{var set of TI}}, \varify{\texttt{var set of TI}}{\texttt{var set of TI}}, \TyOrdering %The pre-defined ordering on sets is the lexicographic ordering on the %corresponding \emph{characteristic arrays}. For example, %\begin{verbatim} % {} < {2} < {1,3} %\end{verbatim} %since %\begin{verbatim} % [0,0,0] < [0,1,0] < [1,0,1]. %\end{verbatim} % %MiniZinc: % \pjs{Better check that this is what we actually want!} The pre-defined ordering on sets is a lexicographic ordering of the \emph{sorted set form}, where \{1,2\} is in sorted set form, for example, but \{2,1\} is not. This means, for instance, \verb'{} < {1,3} < {2}'. %\Rationale{The order based on the characteristic array %seems easier to propagate well (as it reduces to the array case) %than the perhaps more natural one based on the sorted set form.} \TyInit A fixed set variable must be initialised at instance-time; an unfixed set variable need not be. \TyCoercions \coerce{\texttt{par set of TI}}{\texttt{par set of UI}} and \coerce{\texttt{par set of TI}}{\texttt{var set of UI}} and \coerce{\texttt{var set of TI}}{\texttt{var set of UI}}, if \coerce{\texttt{TI}}{\texttt{UI}}. %\pjs{Is this true for MiniZinc?} %Fixed sets can be automatically coerced to arrays; see %section~\ref{Arrays}. This means that array accesses can be used on fixed %sets; \texttt{S[1]} is the smallest element in a fixed set \texttt{S} while %\texttt{S[card(S)]} is the largest. %---------------------------------------------------------------------------% \subsubsection{Arrays} \label{Arrays} %---------------------------------------------------------------------------% \TyOverview MiniZinc arrays are maps from fixed integers to values. Values can be of any type. %When used with integer keys, Zinc arrays %can be used like arrays in languages like Java, but with other types of key %they act like associative arrays. Using floats or types containing floats %as keys can be dangerous because of their imprecise equality comparison, and %an implementation may give a warning in this case. The values can have only have base type-insts. Arrays-of-arrays are not allowed. All arrays are one-dimensional. However, multi-dimensional arrays can be simulated using a tuple as the index, and there is some syntactic sugar to make this easier (see below and in Section~\ref{Array Access Expressions}). MiniZinc arrays can be declared in two different ways. \begin{enumerate} \item \emph{Explicitly-indexed} arrays have index types in the declaration that are finite types. For example: \begin{verbatim} array[0..3] of int: a1; \end{verbatim} For such arrays, the index type specifies exactly the indices that will be in the array---the array's index set is the \emph{domain} of the index type---and if the indices of the value assigned do not match then it is a run-time error. For example, the following assignments cause run-time errors: \begin{verbatim} a1 = [4,6,4,3,2]; % too many elements array[1..5, 1..10] of var float: a5 = []; % too few elements \end{verbatim} \item \emph{Implicitly-indexed} arrays have index types in the declaration that are not finite types. For example: \begin{verbatim} array[int] of int: a6; \end{verbatim} No checking of indices occurs when these variables are assigned. \end{enumerate} The initialisation of an array can be done in a separate assignment statement, which may be present in the model or a separate data file. Arrays can be accessed. See Section~\ref{Array Access Expressions} for details. \TyInsts An array's size must be fixed. Its indices must also have fixed type-insts. Its elements may be fixed or unfixed. \TySyntax An array base type-inst expression tail has this syntax: \begin{productions} \RuleArrayTIExprTail \end{productions} Some example array type-inst expressions: \begin{verbatim} array[1..10] of int list of var int \end{verbatim} Note that \texttt{list of } is just syntactic sugar for \texttt{array[int] of }. \Rationale{Integer-indexed arrays of this form are very common, and so worthy of special support to make things easier for modellers. Implementing it using syntactic sugar avoids adding an extra type to the language, which keeps things simple for implementers.} Because arrays must be fixed-size it is a type-inst error to precede an array type-inst expression with \texttt{var}. % \pjs{Introduce the $index:value$ as a notation to explain arrays?} % Syntactic sugar exists for declaring tuple-indexed arrays. For example, % the second of the following two declarations is syntactic sugar for the % first. % \begin{verbatim} % array[tuple(1..5, 1..4)] of int: a5; % array[1..5, 1..4] of int: a5; % \end{verbatim} \TyFiniteType Yes, if the index types and element type are all finite types. Otherwise, no. The domain of an array type that is a finite array is the set of all distinct arrays whose index set equals the domain of the index type and whose elements are of the array element type. % For example, the domain of % \texttt{array[5..6] of 1..2} is % \verb+{[5:1,6:1], [5:1,6:2], [5:2,6:1], [5:2,6:2]}+. \TyVarifiable No. \TyOrdering Arrays are ordered lexicographically, taking absence of a value for a given key to be before any value for that key. For example, \texttt{[1, 1]} is less than \texttt{[1, 2]}, which is less than \texttt{[1, 2, 3]} and \texttt{array1d(2..4,[0, 0, 0])} is less than \texttt{[1, 2, 3]}. \TyInit An explicitly-indexed array variable must be initialised at instance-time only if its elements must be initialised at instance time. An implicitly-indexed array variable must be initialised at instance-time so that its length and index set is known. \TyCoercions %\coerce{\texttt{set of TI}}{\texttt{array[1..n] of UI}} if %\coerce{\texttt{TI}}{\texttt{UI}}, where %\texttt{n} is the number of elements in the set. The elements of the %resulting array will be in sorted order. %This is handy for initialisation but seems a bit dangerous. %This means that elements of fixed sets can be accessed like array elements, %using square brackets. \coerce{\texttt{array[TI0] of TI}}{\texttt{array[TI0] of UI}} if \coerce{\texttt{TI}}{\texttt{UI}} (i.e.\ coercion of the element type but not the index type). \ignore{ %---------------------------------------------------------------------------% \subsubsection{Tuples} %---------------------------------------------------------------------------% \TyOverview Tuples are fixed-size, heterogeneous collections. They must contain at least two elements; unary tuples are not allowed. \TyInsts Tuples may contain unfixed elements. \TySyntax A tuple base type-inst expression tail has this syntax: \begin{productions} \RuleTupleTIExprTail \end{productions} An example tuple type-inst expression: \begin{verbatim} tuple(int, var float) \end{verbatim} It is a type-inst error to precede a tuple type-inst expression with \texttt{var}. \TyFiniteType Yes, if all its constituent elements are finite types. Otherwise, no. The domain of a tuple type that is a finite type is the Cartesian product of the domains of the element types. For example, the domain of \texttt{tuple(1..2, \{3,5\})} is \verb+{(1,3), (1,5), (2,3), (2,5)}+. \TyVarifiable Yes, if all its constituent elements are varifiable. A tuple is varified by varifying its constituent elements. \TyOrdering Tuples are ordered lexicographically. \TyInit A tuple variable must be initialised at instance-time if any of its constituent elements must be initialised at instance-time. \TyCoercions \coerce{\texttt{tuple(TI1,...,TIn)}}{\texttt{tuple(UI1,...UIn)}}, if \coerce{\texttt{TI1}}{\texttt{UI1}},\ldots,\coerce{\texttt{TIn}}{\texttt{UIn}}. Also, tuples can be automatically coerced to records; see Section~\ref{Records} for details. %---------------------------------------------------------------------------% \subsubsection{Records} \label{Records} %---------------------------------------------------------------------------% \TyOverview Records are fixed-size, heterogeneous collections. They are similar to tuples, but have named fields. Field names in different records can be identical, because each record's field names belong to a different namespace (Section~\ref{Namespaces}). Record field order is significant; the following two record type-insts are distinct and do not match: \begin{verbatim} record(var int: x, var int: y) record(var int: y, var int: x) \end{verbatim} \begin{RationaleEnv} This is necessary to avoid ambiguity when tuples are coerced to records. If field ordering did not matter, we could have this array: \begin{small} \begin{verbatim} [(x:3, y:4), (y:2, x:5), (7,8)] \end{verbatim} \end{small} in which the \texttt{(7,8)} must be coerced to a record, but it is unclear if it should become \texttt{(x:7, y:8)} or \texttt{(y:7, x:8)}. \end{RationaleEnv} \TyInsts Records may contain unfixed elements. \TySyntax A record base type-inst expression tail has this syntax: \begin{productions} \RuleRecordTIExprTail \\ \RuleTIExprAndId \end{productions} An example record type-inst expression: \begin{verbatim} record(int: x, int: y) \end{verbatim} It is a type-inst error to precede a record type-inst expression with \texttt{var}. \TyFiniteType Yes, if all its constituent elements are finite types. Otherwise, no. The domain of a record type that is a finite type is the same as that of a tuple type, but with the fields included. For example, the domain of \texttt{record(1..2:x, \{3,5\}:y)} is \verb+{(x:1,y:3), (x:1,y:5), (x:2,y:3), (x:2,y:5)}+. \TyVarifiable Yes, if all its constituent elements are varifiable. A record is varified by varifying its constituent elements. \TyOrdering Records are ordered lexicographically according to the values of the fields. The field names are irrelevant for comparisons because in order for two records to be compared they must have the same type-inst, in which case the field names and order must be the same. \TyInit A record variable must be initialised at instance-time if any of its constituent elements must be initialised at instance-time. \TyCoercions \coerce{\texttt{tuple(TI1,...,TIn)}}{\texttt{record(UI1:x1,...UIn:xn)}}, if \coerce{\texttt{TI1}}{\texttt{UI1}},\ldots,\coerce{\texttt{TIn}}{\texttt{UIn}}. This is useful for record initialisation. For example, we can initialise a record of type \emph{Task} (defined in Section~\ref{Arbitrarily Constrained Type-insts}) using: \begin{verbatim} Task: T = (10,_,_); \end{verbatim} which initialises \texttt{duration} field with 10 and the variable fields \texttt{start} and \texttt{finish} with `\underscore'. Also, \coerce{\texttt{record(TI1:x1,...,TIn:xn)}} {\texttt{record(UI1:x1,...UIn:xn)}}, if \coerce{\texttt{TI1}}{\texttt{UI1}},\ldots,\coerce{\texttt{TIn}}{\texttt{UIn}}. %---------------------------------------------------------------------------% \subsection{User-defined Types and Type-insts} \label{User-defined Types} %---------------------------------------------------------------------------% This section introduces the properties of the user-defined types and type-insts. The syntax and details of the items that are used to declare these new types are in Section~\ref{Items}. Because these user-defined types have names, their type-inst expressions are simple identifiers. Syntactically, any identifier may be used as a base type-inst expression. However, in a valid model any identifier within a base type-inst expression must be one of: \begin{itemize} %\item the name of a user-defined type or type-inst (type-inst synonym % or enumerated type); \item the name of a fixed set value (Section~\ref{Set Expression Type-insts}). \end{itemize} %---------------------------------------------------------------------------% \subsubsection{Type-inst Synonyms} \label{Type-inst Synonyms} %---------------------------------------------------------------------------% \TyOverview A type-inst synonym is an alternative name for a pre-existing type-inst which can be used interchangeably with the pre-existing type-inst. For example, if \texttt{MyFixedInt} is a synonym for \texttt{par int} then \texttt{MyFixedInt} can be used anywhere \texttt{par int} can, and vice versa. \TyInsts Preceding a type-inst synonym with \texttt{var} varifies it, unless the type-inst is not varifiable, in which case it is a type-inst error. Preceding a type-inst synonym with \texttt{par} has no effect---the \texttt{par} is ignored. \TySyntax A type-inst synonym named ``X'' is represented by the term \texttt{X}. \TyFiniteType As for the pre-existing type-inst. \TyVarifiable Yes, if the pre-existing type-inst is varifiable. \TyOrdering As for the pre-existing type-inst. \TyInit As for the pre-existing type-inst. \TyCoercions As for the pre-existing type-inst. %---------------------------------------------------------------------------% \subsubsection{Enumerated Types} \label{Enumerated Types} %---------------------------------------------------------------------------% \TyOverview Enumerated types (or \emph{enums} for short) provide a set of named alternatives. Unlike many languages, Zinc's enumerated types can have arguments, and each argument has a field name, so they are more like discriminated unions. However, they cannot be recursive. \Rationale{This restriction naturally follows from the decision to disallow recursive functions and predicates (see Section~\ref{Basic Properties}). Without such capabilities, recursive data structures are of little use as there is no general way to traverse them.} We distinguish between \emph{flat} enums, in which all the alternatives have no arguments, and \emph{non-flat} enums, in which some or all alternatives have arguments. Each alternative is identified by its \emph{case name}. \TyInsts Flat enums can be fixed or unfixed. Non-flat enums cannot be preceded by \texttt{var}, but they may contain unfixed elements. \TySyntax Variables of an enumerated type named ``X'' are represented by the term \texttt{X} or \texttt{par X} if fixed, and (flat enums only) \texttt{var X} if unfixed. \TyFiniteType If flat, yes. If non-flat, only if all its constituent elements (in all alternatives) are finite types; otherwise, no. The domain of a flat enum is the set containing all of its case names. The domain of a non-flat enum is the set containing all the possible values of that enum. For example, these two enums: \begin{verbatim} enum C = { R, G, B }; enum X = { a(1..3:x), b(bool:y), c }; \end{verbatim} have these domains: \begin{verbatim} { R, G, B } { a(x:1), a(x:2), a(x:3), b(y:false), b(y:true), c } \end{verbatim} \TyVarifiable For flat enums: \varify{\texttt{par X}}{\texttt{var X}}, \varify{\texttt{var X}}{\texttt{var X}}. For non-flat enums: no. \TyOrdering When two enum values with different case names are compared, the value with the case name that is declared first is considered smaller than the value with the case name that is declared second. If the case names are the same, the ordering is lexicographic on the case arguments (if there are any). \TyInit A fixed flat enum variable must be initialised at instance-time; an unfixed flat enum variable need not be. A non-flat enum variable must be initialised at instance-time. \TyCoercions For flat enums: \coerce{\texttt{par X}}{\texttt{var X}}. For non-flat enums: none. } %---------------------------------------------------------------------------% \subsubsection{Option Types} \label{option types} %---------------------------------------------------------------------------% \TyOverview Option types defined using the \texttt{opt} type constructor, define types that may or may not be there. They are similar to \texttt{Maybe} types of Haskell implicity adding a new value \texttt{<>} to the type. \TyInsts The argument of an option type must be one of the base types \texttt{bool}, \texttt{int} or \texttt{float}. \TySyntax The annotation type is written \texttt{opt } where \texttt{} if one of the three base types, or one of their constrained instances. \TyFiniteType Yes if the underlying type is finite, otherwise no. \TyVarifiable Yes. \TyOrdering \texttt{<>} is always less than any other value in the type. But beware that overloading of operators like \texttt{<} is different for option types. \TyInit A fixed \texttt{opt} type variable must be initialised at instance-time, a variable \texttt{opt} type variable need not be. \TyCoercions None. %---------------------------------------------------------------------------% \subsubsection{The Annotation Type \texttt{ann}} \label{the annotation type} %---------------------------------------------------------------------------% \TyOverview The annotation type, \texttt{ann}, can be used to represent arbitrary term structures. It is augmented by annotation items (\ref{Annotation Items}). \TyInsts \texttt{ann} is always considered unfixed, because it may contain unfixed elements. It cannot be preceded by \texttt{var}. \TySyntax The annotation type is written \texttt{ann}. \TyFiniteType No. \TyVarifiable No. \TyOrdering N/A. Annotation types do not have an ordering defined on them. \TyInit An \texttt{ann} variable must be initialised at instance-time. \TyCoercions None. \ignore{ %---------------------------------------------------------------------------% \subsection{Other Types and Type-insts} \label{Other Types} %---------------------------------------------------------------------------% %---------------------------------------------------------------------------% \subsubsection{Type-inst Variables} \label{Type-inst Variables} %---------------------------------------------------------------------------% \TyOverview Type-inst variables allow parametric polymorphism. They can appear in MiniZinc predicate and function arguments and return type-insts, in let expressions within predicate and function bodies, and in annotation declarations; if one is used outside a function or predicate or annotation declaration it is a type-inst error. \TyInsts A type-inst variable expression consists of a type-inst variable and an optional prefix. Type-inst variables can be prefixed by \texttt{par}, in which case they match any fixed type-inst; the same is true if they lack a prefix. %Type-inst variables can also be prefixed by \texttt{any}, in which case they %match any first-order type-inst. The meanings of the prefixes are discussed in further detail in Section~\ref{Parametric Polymorphism}. \TySyntax A type-inst variable expression tail has this syntax: \begin{productions} \RuleTIVariableExprTail \end{productions} Some example type-inst variable expressions: \begin{verbatim} $T par $U3 \end{verbatim} \TyFiniteType No. This is because they can be bound to any type-inst, and not all type-insts are finite. \TyVarifiable No. This is because they can be bound to any type-inst, and not all type-insts can be varified. \TyOrdering Values of equal type-inst variables can be compared. The comparison used will be the comparison of the underlying type-insts. This is possible because all type-insts have a built-in ordering. \TyInit A variable with a type-inst variable as its type-inst (which can only appear inside predicate and function bodies) must be initialised. \TyCoercions None. %\coerce{\texttt{par \$T}}{\texttt{any \$T}}. } \ignore{ %---------------------------------------------------------------------------% \subsubsection{Higher-order Types} \label{Higher-order Types} %---------------------------------------------------------------------------% \TyOverview Operations (e.g.~predicates) have higher-order types. Operations can be used as values when passed as the first argument to \texttt{foldl} or \texttt{foldr}. They can also be used as arguments to annotations; annotation declarations are the only place where operation type-inst expressions are permitted. \TyInsts The type-inst of a higher-order type is determined by the type-insts it can take as its arguments, and its return type-inst. A higher-order type value is never considered fixed, and so cannot be used as the element of a set, for example. \TySyntax An operation type-inst expression tail has this syntax: \begin{productions} \RuleOpTIExprTail \end{productions} Some example type-inst variable expressions: \begin{verbatim} op(int:(int)); op(var bool:(float, any $T)); \end{verbatim} Note that operation type-inst expressions cannot be written for nullary operations (i.e.~those lacking arguments). \Rationale{This is because it is difficult to distinguish the name of a nullary operation from a call to it, and so passing nullary operations is difficult. Furthermore, they are little to no use, so they are unlikely to be missed.} \TyFiniteType No. \TyVarifiable No. \TyOrdering N/A. Higher-order types cannot be used in comparisons; it is a run-time error if they are. \TyInit N/A. Variables cannot have higher-order types. \TyCoercions None. } %---------------------------------------------------------------------------% \subsection{Constrained Type-insts} \label{Constrained Type-insts} %---------------------------------------------------------------------------% One powerful feature of MiniZinc is \emph{constrained type-insts}. A constrained type-inst is a restricted version of a \emph{base} type-inst, i.e.~a type-inst with fewer values in its domain. %---------------------------------------------------------------------------% \subsubsection{Set Expression Type-insts} \label{Set Expression Type-insts} %---------------------------------------------------------------------------% Three kinds of expressions can be used in type-insts. \begin{enumerate} \item Integer ranges: e.g.~\texttt{1..3}. \item Set literals: e.g.~\texttt{var \{1,3,5\}}. \item Identifiers: the name of a set parameter (which can be global, let-local, the argument of a predicate or function, or a generator value) can serve as a type-inst. \end{enumerate} In each case the base type is that of the set's elements, and the values within the set serve as the domain. For example, whereas a variable with type-inst \texttt{var int} can take any integer value, a variable with type-inst \texttt{var 1..3} can only take the value 1, 2 or 3. All set expression type-insts are finite types. Their domain is equal to the set itself. %---------------------------------------------------------------------------% \subsubsection{Float Range Type-insts} %---------------------------------------------------------------------------% Float ranges can be used as type-insts, e.g.~\verb+1.0 .. 3.0+. These are treated similarly to integer range type-insts, although \verb+1.0 .. 3.0+ is not a valid expression whereas \verb+1 .. 3+ is. Float ranges are not finite types. \ignore{ %---------------------------------------------------------------------------% \subsubsection{Arbitrarily Constrained Type-insts} \label{Arbitrarily Constrained Type-insts} %---------------------------------------------------------------------------% A more general form of constrained type-inst allows an arbitrary Boolean \emph{type-inst constraint} expression to be applied to a \emph{base} type-inst. Here are two examples of arbitrarily constrained type-inst expressions. The first is a fixed integer in the range 1--3, and the second is an unfixed non-negative float. \begin{verbatim} (par int: i where i in 1..3): dom; (var float: f where f >= 0) : fplus; \end{verbatim} The base type-inst appears before the `:'. The identifiers \texttt{i} and \texttt{f} are local identifiers used in the Boolean expression after the \texttt{where} keyword. The scope of the local identifiers \texttt{i} and \texttt{f} extends to the end of the Boolean expression after the \texttt{where}. An arbitrarily constrained type-inst is finite only if its base type-inst is finite. Its domain is that of its base type-inst, minus those elements that do not satisfy its constraint. Finiteness is thus the main difference between set expression type-insts (Section~\ref{Set Expression Type-insts}) and arbitrarily constrained type-insts. For example, in the following three lines, the first type-inst is equivalent to the second, with one exception. \begin{verbatim} par 1..3 (par int: i where i in 1..3) var {1,2,3} (var int: i where i in {1,2,3}) MySet ( int: i where i in MySet) \end{verbatim} The exception is that the type-insts on the left-hand side are finite, whereas those on the right are non-finite. Every float range type-inst has an equivalent arbitrarily constrained type-inst. For example, the following two type-insts are equivalent: \begin{verbatim} 1.0 .. 3.0 (float: f where 1.0 <= f /\ f <= 3.0) \end{verbatim} An unconstrained type-inst can be viewed as an arbitrarily constrained type-inst with a \textit{true} constraint. For example, the following two type-insts are equivalent: \begin{verbatim} par int (par int: i where true) \end{verbatim} The Boolean expression associated with a variable declared to have an arbitrarily constrained type-inst is either tested at instance-time if the variable is a parameter or else generates a constraint if it is a decision variable. An arbitrarily constrained type-inst is varified by varifying its base type-inst. Records can use type-inst constraints like other type-insts, for example: \begin{verbatim} type Task = (record(int: duration, var int: start, var int: finish ): t where t.finish = t.start + t.duration); \end{verbatim} Non-flat enums can also involve type-inst constraints; see Section~\ref{Enum Items} for details. } %===========================================================================% \section{Expressions} \label{Expressions} %===========================================================================% %---------------------------------------------------------------------------% \subsection{Expressions Overview} \label{Expressions Overview} %---------------------------------------------------------------------------% Expressions represent values. They occur in various kinds of items. They have the following syntax: \resolvedcomment{rafe}{ I'd like to have an `\texttt{expr where \{...\}}' construct, a la Haskell, where the ... could contain definitions and constraints sections. }{ Perhaps a good idea, but we won't do it for now because it's extra complexity and it's unclear how useful it will be. Plus we have let expressions, which are similar. } \begin{productions} \RuleExpr \\ \RuleExprAtom \\ \RuleExprBinopTail \\ \RuleExprAtomHead \\ \RuleExprAtomTail \end{productions} Expressions can be composed from sub-expressions combined with operators. All operators (binary and unary) are described in Section~\ref{Operators}, including the precedences of the binary operators. All unary operators bind more tightly than all binary operators. Expressions can have one or more annotations. Annotations bind more tightly than unary and binary operator applications, but less tightly than access operations and non-operator applications. In some cases this binding is non-intuitive. For example, in the first three of the following lines, the annotation \texttt{a} binds to the identifier expression \texttt{x} rather than the operator application. However, the fourth line features a non-operator application (due to the single quotes around the \texttt{not}) and so the annotation binds to the whole application. \begin{verbatim} not x::a; not (x)::a; not(x)::a; 'not'(x)::a; \end{verbatim} Section~\ref{Annotations} has more on annotations. Expressions can be contained within parentheses. The array access operations all bind more tightly than unary and binary operators and annotations. %The %access operations can be chained and they associate to the left. For %example, these two access operations are equivalent: %\begin{verbatim} % x = a[1].field.1; % x = ((a[1]).field).1; %\end{verbatim} They are described in more detail in Sections~\ref{Array Access Expressions}. %, \ref{Tuple Access Expressions}, \ref{Record Access %Expressions} and \ref{Non-flat Enum Access Expressions}. The remaining kinds of expression atoms (from \nt{ident} to \nt{gen-call-expr}) are described in Sections~\ref{Identifier Expressions and Quoted Operator Expressions}--\ref{Generator Call Expressions}. We also distinguish syntactically valid numeric expressions. This allows range types to be parsed correctly. \begin{productions} \RuleNumExpr \\ \RuleNumExprAtom \\ \RuleNumExprBinopTail \\ \RuleNumExprAtomHead \\ \end{productions} %---------------------------------------------------------------------------% \subsection{Operators} \label{Operators} %---------------------------------------------------------------------------% Operators are functions that are distinguished by their syntax in one or two ways. First, some of them contain non-alphanumeric characters that normal functions do not (e.g.~`\texttt{+}'). Second, their application is written in a manner different to normal functions. We distinguish between binary operators, which can be applied in an infix manner (e.g.~\texttt{3 + 4}), and unary operators, which can be applied in a prefix manner without parentheses (e.g.~\texttt{not x}). We also distinguish between built-in operators and user-defined operators. The syntax is the following: \begin{productions} \RuleBuiltinOp \\ \RuleBinOp \\ \RuleBuiltinBinOp \\ \RuleBuiltinUnOp \end{productions} Again, we syntactically distinguish numeric operators. \begin{productions} \RuleNumBinOp \\ \RuleBuiltinNumBinOp \\ \RuleBuiltinNumUnOp \end{productions} % \pjs{Where do we seay something about the unicode versions of these?} Some operators can be written using their unicode symbols, which are listed in Table~\ref{bin-ops-unicode} (recall that MiniZinc input is UTF-8). \begin{table}[t] \centering \begin{tabular}{lcl} \hline Operator & Unicode symbol & UTF-8 code \\ \hline \texttt{<->} & $\leftrightarrow$ & E2~86~94\\ \texttt{->} & $\rightarrow$ & E2~86~92\\ \texttt{<-} & $\leftarrow$ & E2~86~90\\ \texttt{not} & $\lnot$ & C2~AC\\ \verb+\/+ & $\lor$ & E2~88~A8\\ \verb+/\+ & $\land$ & E2~88~A7\\ \texttt{!=} & $\neq$ & E2~89~A0\\ \texttt{<=} & $\leq$ & E2~89~A4\\ \texttt{>=} & $\geq$ & E2~89~A5\\ \texttt{in} & $\in$ & E2~88~88\\ \texttt{subset} & $\subseteq$ & E2~8A~86\\ \texttt{superset} & $\supseteq$ & E2~8A~87\\ \texttt{union} & $\cup$ & E2~88~AA\\ \texttt{intersect} & $\cap$ & E2~88~A9\\ \end{tabular} \caption{Unicode equivalents of binary operators.} \label{bin-ops-unicode} \end{table} The binary operators are listed in Table~\ref{bin-ops}. %-----------------------------------------------------------------------------% \begin{table}[t] \centering \begin{tabular}{lll} \hline Symbol(s) & Assoc.& Prec. \\ \hline \texttt{<->} & left & 1200 \\ \texttt{->} & left & 1100 \\ \texttt{<-} & left & 1100 \\ \verb+\/+ & left & 1000 \\ \texttt{xor} & left & 1000 \\ \verb+/\+ & left & 900 \\ \texttt{<} & none & 800 \\ \texttt{>} & none & 800 \\ \texttt{<=} & none & 800 \\ \texttt{>=} & none & 800 \\ \texttt{==}, \texttt{=} & none & 800 \\ \texttt{!=} & none & 800 \\ \texttt{in} & none & 700 \\ \texttt{subset} & none & 700 \\ \texttt{superset} & none & 700 \\ \texttt{union} & left & 600 \\ \texttt{diff} & left & 600 \\ \texttt{symdiff} & left & 600 \\ \texttt{..} & none & 500 \\ \texttt{+} & left & 400 \\ \texttt{-} & left & 400 \\ \texttt{*} & left & 300 \\ \texttt{div} & left & 300 \\ \texttt{mod} & left & 300 \\ \texttt{/} & left & 300 \\ \texttt{intersect} & left & 300 \\ \texttt{++} & right & 200 \\ \texttt{`}\nt{ident}\texttt{`} & left & 100 \\ \hline \end{tabular} \caption{Binary infix operators. A lower precedence number means tighter binding; for example, \texttt{1+2*3} is parsed as \texttt{1+(2*3)} because `\texttt{*}' binds tighter than `\texttt{+}'. Associativity indicates how chains of operators with equal precedences are handled; for example, \texttt{1+2+3} is parsed as \texttt{(1+2)+3} because `\texttt{+}' is left-associative, \texttt{a++b++c} is parsed as \texttt{a++(b++c)} because `\texttt{++}' is right-associative, and \texttt{1 0 then 1 else 0 endif \end{verbatim} The presence of the \texttt{endif} avoids possible ambiguity when an if-then-else expression is part of a larger expression. The type-inst of the ``if'' expression must be \texttt{par bool} or \texttt{var bool}. % In the future we may allow it to also be \texttt{var bool}. The ``then'' and ``else'' expressions must have the same type-inst, or be coercible to the same type-inst, which is also the type-inst of the whole expression. If the ``if'' expression is \texttt{var bool} then the type-inst of the ``then'' and ``else'' expressions must be varifiable. If the ``if'' expression is \texttt{par bool} then evaluation of if-then-else expressions is lazy---the condition is evaluated, and then only one of the ``then'' and ``else'' branches are evaluated, depending on whether the condition succeeded or failed. This is not the case if it is \texttt{var bool}. \ignore{ %---------------------------------------------------------------------------% \subsubsection{Case Expressions} \label{Case Expressions} %---------------------------------------------------------------------------% Zinc provides case expressions for handling the different cases in an enum. Case expressions have this syntax: \resolvedcomment{pjs}{ I THINK WE NEED PROPER CASE EXPRESSIONS!\\ \indent\texttt{multi\_point: r;}\\ \indent\texttt{int M: case r \{ intp(a,\_) --> a , floatp(u,v) --> ceil(u+v) \};}}{ Decided to keep as is for the moment, for simplicity. } \begin{productions} \RuleCaseExpr \\ \RuleCaseExprCase \end{productions} For example, we can use the \texttt{multi\n{}point} record in Section~\ref{multipoint} with the following code: \begin{verbatim} multi_point: r; int: M = case r { int_point --> r.ix, float_point --> 0, }; \end{verbatim} The comma after the final case is optional. The type-inst of the case selection expression must be a fixed flat enum or a non-flat enum. The type-inst of every result expression must be the same, or be coercible to the same type-inst, which is also the type-inst of the whole expression. It is a static error if any case name is not covered by the case statement. Currently MiniZinc does not support pattern matching. This may be supported in the future. } %---------------------------------------------------------------------------% \subsubsection{Let Expressions} \label{Let Expressions} %---------------------------------------------------------------------------% Let expressions provide a way of introducing local names for one or more expressions and local constraints that can be used within another expression. They are particularly useful in user-defined operations. Let expressions have this syntax: \begin{productions} \RuleLetExpr \\ \RuleLetItem \end{productions} For example: \begin{verbatim} let { int: x = 3, int: y = 4; } in x + y; let { var int: x; constraint x >= y /\ x >= -y /\ (x = y \/ x = -y); } in x \end{verbatim} The scope of a let local variable covers: \begin{itemize} \item The type-inst and initialisation expressions of any subsequent variables within the let expression (but not the variable's own initialisation expression). \item The expression after the \texttt{in}, which is parsed as greedily as possible. \end{itemize} A variable can only be declared once in a let expression. Thus in the following examples the first is acceptable but the rest are not: \begin{verbatim} let { int: x = 3; int: y = x; } in x + y; % ok let { int: y = x; int: x = 3; } in x + y; % x not visible in y's defn. let { int: x = x; } in x; % x not visible in x's defn. let { int: x = 3; int: x = 4; } in x; % x declared twice \end{verbatim} The type-inst expressions can include type-inst variables if the let is within a function or predicate body in which the same type-inst variables were present in the function or predicate signature. The initialiser for a let local variable can be omitted only if the variable is a decision variable. For example: \begin{verbatim} let { var int: x; } in ...; % ok let { int: x; } in ...; % illegal \end{verbatim} The type-inst of the entire let expression is the type-inst of the expression after the \texttt{in} keyword. There is a complication involving let expressions in negative contexts. A let expression occurs in a negative context if it occurs in an expression of the form \texttt{not X}, \texttt{X <-> Y}, or in the sub-expression \texttt{X} in \texttt{X -> Y} or \texttt{Y <- X}, or in a subexpression \texttt{bool2int(X)}. If a let expression is used in a negative context, then any let-local decision variables must be defined only in terms of non-local variables and parameters. This is because local variables are implicitly existentially quantified, and if the let expression occurred in a negative context then the local variables would be effectively universally quantified which is not supported by MiniZinc. Constraints in let expressions float to the nearest enclosing Boolean context. For example \begin{verbatim} constraint b -> x + let { var 0..2: y; constraint y != -1;} in y >= 4; \end{verbatim} is equivalent to \begin{verbatim} var 0..2: y; constraint b -> (x + y >= 4 /\ y != 1); \end{verbatim} %---------------------------------------------------------------------------% \subsubsection{Call Expressions} %---------------------------------------------------------------------------% Call expressions are used to call predicates and functions. Call expressions have this syntax: \begin{productions} \RuleCallExpr \end{productions} For example: \begin{verbatim} x = min(3, 5); \end{verbatim} The type-insts of the expressions passed as arguments must match the argument types of the called predicate/function. The return type of the predicate/function must also be appropriate for the calling context. Note that a call to a function or predicate with no arguments is syntactically indistinguishable from the use of a variable, and so must be determined during type-inst checking. Evaluation of the arguments in call expressions is strict---all arguments are evaluated before the call itself is evaluated. Note that this includes Boolean operations such as \verb+/\+, \verb+\/+, \texttt{->} and \texttt{<-} which could be lazy in one argument. The one exception is \texttt{assert}, which is lazy in its third argument (Section~\ref{Other Operations}). \Rationale{Boolean operations are strict because: (a) this minimises exceptional cases; (b) in an expression like \texttt{A -> B}, where \texttt{A} is not fixed and \texttt{B} causes an abort, the appropriate behaviour is unclear if laziness is present; and (c) if a user needs laziness, an if-then-else can be used.} The order of argument evaluation is not specified. \Rationale{Because MiniZinc is declarative, there is no obvious need to specify an evaluation order, and leaving it unspecified gives implementors some freedom.} %---------------------------------------------------------------------------% \subsubsection{Generator Call Expressions} \label{Generator Call Expressions} %---------------------------------------------------------------------------% MiniZinc has special syntax for certain kinds of call expressions which makes models much more readable. Generator call expressions have this syntax: \begin{productions} \RuleGenCallExpr \end{productions} % A generator call expression \texttt{P(Gs)(E)} is equivalent to the call expression \texttt{P([E | Gs])}. For example, the expression: \begin{verbatim} forall(i,j in Domain where i= 0); type Domain = 1..n; \end{verbatim} It is a type-inst error if a type-inst synonym is declared and/or defined more than once in a model. Type-inst synonym items can be annotated. Section~\ref{Annotations} has more details on annotations. All type-inst synonyms must be defined at model-time. %---------------------------------------------------------------------------% \subsection{Enum Items} \label{Enum Items} %---------------------------------------------------------------------------% Enumerated type items have this syntax: \begin{productions} \RuleEnumItem \\ \RuleEnumCases \\ \RuleEnumCase \end{productions} An example of a flat enum: \begin{verbatim} enum country = {Australia, Canada, China, England, USA}; \end{verbatim} An example of a non-flat enum: \label{multipoint} \begin{verbatim} enum multi_point = { int_point(int: ix, int: iy), float_point(float: fx, float: fy) }; \end{verbatim} Each alternative is called an \emph{enum case}. The identifier used to name each case (e.g.~\texttt{Australia} and \texttt{float\n{}point}) is called the \emph{enum case name}. Enums can be constrained by using a type-inst synonym (Section~\ref{Type-inst Synonym Items}) and a case expression (Section~\ref{Case Expressions}). For example: \begin{verbatim} type multi_point2 = (multi_point: p where case p { int_point --> p.ix > p.iy, float_point --> p.fx > p.fy }); \end{verbatim} Because enum case names all reside in the top-level namespace (Section~\ref{Namespaces}), case names in different enums must be distinct. As for field names in non-flat enums, all field names in a single enum must be distinct to avoid possible ambiguities. An enum can be declared but not defined, in which case it must be defined elsewhere. For non-flat enums, ``elsewhere'' must be within the model. For flat enums, ``elsewhere'' must be within the model, or in a data file. For example, a model file could contain this: \begin{verbatim} enum Workers; enum Shifts; \end{verbatim} and the data file could contain this: \begin{verbatim} enum Workers = { welder, driller, stamper }; enum Shifts = { idle, day, night }; \end{verbatim} Sometimes it is useful to be able to refer to one of the enum case names within the model. This can be achieved by using a variable. The model would read: \begin{verbatim} enum Shifts; Shifts idle; % Variable representing the idle constant. \end{verbatim} and the data file: \begin{verbatim} enum Shifts = { idle_const, day, night }; idle = idle_const; % Assignment to the variable. \end{verbatim} Although the constant \texttt{idle\n{}const} cannot be mentioned in the model, the variable \texttt{idle} can be. All enums must be defined at instance-time. Enum items can be annotated. Section~\ref{Annotations} has more details on annotations. % For each enumerated type $T$ MiniZinc automatically creates the function % \begin{verbatim} % toInt(T):int % \end{verbatim} % which maps elements to their index in $T$. } %---------------------------------------------------------------------------% \subsection{Include Items} \label{Include Items} %---------------------------------------------------------------------------% Include items allow a model to be split across multiple files. They have this syntax: \begin{productions} \RuleIncludeItem \end{productions} %% For example: \begin{verbatim} include "foo.zinc"; \end{verbatim} includes the file \texttt{foo.zinc}. Include items are particularly useful for accessing libraries or breaking up large models into small pieces. They are not, as Section~\ref{Model Instance Files} explains, used for specifying data files. If the given name is not a complete path then the file is searched for in an implementation-defined set of directories. The search directories must be able to be altered with a command line option. %---------------------------------------------------------------------------% \subsection{Variable Declaration Items} \label{Declarations} %---------------------------------------------------------------------------% Variable declarations have this syntax: \begin{productions} \RuleVarDeclItem \end{productions} For example: \begin{verbatim} int: A = 10; \end{verbatim} It is a type-inst error if a variable is declared and/or defined more than once in a model. A variable whose declaration does not include an assignment can be initialised by a separate assignment item (Section~\ref{Assignments}). For example, the above item can be separated into the following two items: \begin{verbatim} int: A; ... A = 10; \end{verbatim} All variables that contain a parameter component must be defined at instance-time. Variables can have one or more annotations. Section~\ref{Annotations} has more on annotations. %---------------------------------------------------------------------------% \subsection{Assignment Items} \label{Assignments} %---------------------------------------------------------------------------% Assignments have this syntax: \begin{productions} \RuleAssignItem \end{productions} %% For example: \begin{verbatim} A = 10; \end{verbatim} % \pjs{Add something about automatic coercion of index sets?} %---------------------------------------------------------------------------% \subsection{Constraint Items} \label{Constraint Items} %---------------------------------------------------------------------------% Constraint items form the heart of a model. Any solutions found for a model will satisfy all of its constraints. Constraint items have this syntax: \begin{productions} \RuleConstraintItem \end{productions} %% For example: \begin{verbatim} constraint a*x < b; \end{verbatim} The expression in a constraint item must have type-inst \texttt{par bool} or \texttt{var bool}; note however that constraints with fixed expressions are not very useful. %---------------------------------------------------------------------------% \subsection{Solve Items} \label{Solve Items} %---------------------------------------------------------------------------% \resolvedcomment{njn} {Nb: the annotation cannot go after the satisfy/maximize/minimize keyword, because in "solve maximize :: foo(bar)..." you can't tell if the "(bar)" is an argument list for the 'foo', or a parenthesised expression. This screws up the grammar when expressed with yacc.}{} Every model must have exactly one solve item. Solve items have the following syntax: \begin{productions} \RuleSolveItem \end{productions} Example solve items: \begin{verbatim} solve satisfy; solve maximize a*x + y - 3*z; \end{verbatim} The solve item determines whether the model represents a constraint satisfaction problem or an optimisation problem. In the latter case the given expression is the one to be minimized/maximized. The expression in a minimize/maximize solve item can have integer or float type. \Rationale{This is possible because all type-insts have a defined order.} Note that having an expression with a fixed type-inst in a solve item is not very useful as it means that the model requires no optimisation. Solve items can be annotated. Section~\ref{Annotations} has more details on annotations. %---------------------------------------------------------------------------% \subsection{Output Items} \label{Output Items} %---------------------------------------------------------------------------% Output items are used to present the solutions of a model instance. They have the following syntax: \begin{productions} \RuleOutputItem \end{productions} For example: \begin{verbatim} output ["The value of x is ", show(x), "!\n"]; \end{verbatim} The expression must have type-inst \texttt{array[int] of par string}. It can be composed using the built-in operator \texttt{++} and the built-in functions \texttt{show}, \texttt{show\_int}, and \texttt{show\_float} (Appendix~\ref{builtins}). The output is the concatenation of the elements of the array. If no output item is present, the implementation should print all the global variables and their values in a readable format. %---------------------------------------------------------------------------% \subsection{Annotation Items} \label{Annotation Items} %---------------------------------------------------------------------------% Annotation items are used to augment the \texttt{ann} type. They have the following syntax: \begin{productions} \RuleAnnotationItem \end{productions} For example: \begin{verbatim} annotation solver(int: kind); \end{verbatim} It is a type-inst error if an annotation is declared and/or defined more than once in a model. The use of annotations is described in Section~\ref{Annotations}. %---------------------------------------------------------------------------% \subsection{User-defined Operations} \label{preds and fns} %---------------------------------------------------------------------------% % XXX: not saying if operations need to be defined. Implementation % currently requires functions and tests to be defined if used, but % predicates can be bodyless even if used. Should perhaps require functions % to be defined even if they're not used (like parameters), and make tests % like predicates? MiniZinc models can contain user-defined operations. They have this syntax: \begin{productions} \RulePredicateItem \\ \RuleTestItem \\ \RuleFunctionItem \\ \RuleOperationItemTail \\ \RuleParams \\ \end{productions} The type-inst expressions can include type-inst variables in the function and predicate declaration. For example, predicate \texttt{even} checks that its argument is an even number. \begin{verbatim} predicate even(var int: x) = x mod 2 = 0; \end{verbatim} %Predicate \texttt{serial} constrains the resistor \texttt{z} to be %equivalent to connecting the two resistors \texttt{x} and \texttt{y} in %series (the fields \texttt{r} and \texttt{i} represent resistance and %current respectively). %\begin{verbatim} % type Resistor = record(var int: r, var int: i); % predicate serial(Resistor: x, Resistor: y, Resistor: z) = % z.r = x.r + y.r /\ % z.i = x.i /\ % z.i = y.i; %\end{verbatim} A predicate supported natively by the target solver can be declared as follows: \begin{verbatim} predicate alldifferent(array [int] of var int: xs); \end{verbatim} Predicate declarations that are natively supported in MiniZinc are restricted to using FlatZinc types (for instance, multi-dimensional and non-1-based arrays are forbidden). % \pjs{need to fix this if we allow2d arrays in FlatZinc!} Declarations for user-defined operations can be annotated. Section~\ref{Annotations} has more details on annotations. \subsubsection{Basic Properties} \label{Basic Properties} The term ``predicate'' is generally used to refer to both test items and predicate items. When the two kinds must be distinguished, the terms ``test item'' and ``predicate item'' can be used. The return type-inst of a test item is implicitly \texttt{par bool}. The return type-inst of a predicate item is implicitly \texttt{var bool}. % \pjs{Can predicates and functionsbe recursive now?} Predicates and functions are allowed to be recursive. Termination of a recursive function call depends solely on its fixed arguments, i.e., recursive functions and predicates cannot be used to define recursively constrained variables. % \Rationale{This ensures that the satisfiability of models is decidable.} Predicates and functions introduce their own local names, being those of the formal arguments. The scope of these names covers the predicate/function body. Argument names cannot be repeated within a predicate/function declaration. %MiniZinc is mostly a first-order language, so operations cannot, in %general, be used as values. The only exception to this is that they may be %given as the first argument to \texttt{foldl} or \texttt{foldr}, and as %arguments in annotation literals (see Section~\ref{Higher-order Types}). \subsubsection{Ad-hoc polymorphism} MiniZinc supports ad-hoc polymorphism via overloading. Functions and predicates (both built-in and user-defined) can be overloaded. A name can be overloaded as both a function and a predicate. It is a type-inst error if a single version of an overloaded operation with a particular type-inst signature is declared and/or defined more than once in a model. For example: \begin{verbatim} predicate p(1..5: x); predicate p(1..5: x) = true; % error: repeated declaration \end{verbatim} The combination of overloading and coercions can cause problems. Two overloadings of an operation are said to ``overlap'' if they could match the same arguments. For example, the following overloadings of \texttt{p} overlap, as they both match the call \texttt{p(3)}. \begin{verbatim} predicate p(par int: x); predicate p(var int: x); \end{verbatim} However, the following two predicates do not overlap because they cannot match the same argument: \begin{verbatim} predicate q(int: x); predicate q(set of int: x); \end{verbatim} We avoid two potential overloading problems by placing some restrictions on overlapping overloadings of operations. \begin{enumerate} \item The first problem is ambiguity. Different placement of coercions in operation arguments may allow different choices for the overloaded function. For instance, if a MiniZinc function \texttt{f} is overloaded like this: \begin{verbatim} function int: f(int: x, float: y) = 0; function int: f(float: x, int: y) = 1; \end{verbatim} then \texttt{f(3,3)} could be either 0 or 1 depending on coercion/overloading choices. To avoid this problem, any overlapping overloadings of an operation must be semantically equivalent with respect to coercion. For example, the two overloadings of the predicate \texttt{p} above must have bodies that are semantically equivalent with respect to overloading. Currently, this requirement is not checked and the modeller must satisfy it manually. In the future, we may require the sharing of bodies among different versions of overloaded operations, which would provide automatic satisfaction of this requirement. \item The second problem is that certain combinations of overloadings could require a MiniZinc implementation to perform combinatorial search in order to explore different choices of coercions and overloading. For example, if function \texttt{g} is overloaded like this: \begin{verbatim} function float: g(int: t1, float: t2) = t2; function int : g(float: t1, int: t2) = t1; \end{verbatim} then how the overloading of \texttt{g(3,4)} is resolved depends upon its context: \begin{verbatim} float: s = g(3,4); int: t = g(3,4); \end{verbatim} In the definition of \texttt{s} the first overloaded definition must be used while in the definition of \texttt{t} the second must be used. To avoid this problem, all overlapping overloadings of an operation must be closed under intersection of their input type-insts. That is, if overloaded versions have input type-inst $(S_1,....,S_n)$ and $(T_1,...,T_n)$ then there must be another overloaded version with input type-inst $(R_1,...,R_n)$ where each $R_i$ is the greatest lower bound (\emph{glb}) of $S_i$ and $T_i$. Also, all overlapping overloadings of an operation must be monotonic. That is, if there are overloaded versions with input type-insts $(S_1,....,S_n)$ and $(T_1,...,T_n)$ and output type-inst $S$ and $T$, respectively, then $S_i \preceq T_i$ for all $i$, implies $S \preceq T$. At call sites, the matching overloading that is lowest on the type-inst lattice is always used. For \texttt{g} above, the type-inst intersection (or \emph{glb}) of \texttt{(float,int)} and \texttt{(float,int)} is \texttt{(int,int)}. Thus, the overloaded versions are not closed under intersection and the user needs to provide another overloading for \texttt{g} with input type-inst \texttt{(int,int)}. The natural definition is: \begin{verbatim} function int: g(int: t1, int: t2) = t1; \end{verbatim} Once \texttt{g} has been augmented with the third overloading, it satisfies the monotonicity requirement because the output type-inst of the third overloading is \texttt{int} which is less than the output type-inst of the original overloadings. Monotonicity and closure under type-inst conjunction ensure that whenever an overloaded function or predicate is reached during type-inst checking, there is always a unique and safe ``minimal'' version to choose, and so the complexity of type-inst checking remains linear. Thus in our example \texttt{g(3,4)} is always resolved by choosing the new overloaded definition. \end{enumerate} \ignore{ \subsubsection{Parametric Polymorphism} \label{Parametric Polymorphism} \pjs{Better check what it actually does!} MiniZinc supports parametric polymorphism of functions and predicates via type-inst variables. For example, function \texttt{min\n{}of\n{}two} takes two parameters and gives their minimum. \begin{verbatim} function $T:min_of_two($T: x, $T: y) = if x <= y then x else y endif; \end{verbatim} This function is possible because every type has a built-in ordering. Section~\ref{Type-inst Variables} explained that type-inst variables can have no prefix (or, equivalently, a \texttt{par} prefix). The prefixes are necessary for precise type-inst signatures of some user-defined operations. For example, consider the following two definitions of a function \texttt{between}: \begin{verbatim} par bool: function between(par $T: x, par $T: y, par $T: z) = (x <= y /\ y <= z) \/ (z <= y /\ y <= x); var bool: function between($T: x, $T: y, $T: z) = (x <= y /\ y <= z) \/ (z <= y /\ y <= x); \end{verbatim} The first version has a more precise return type-inst. The \texttt{par} prefixes is needed to express the difference between these two versions. \pjs{The example above is causes an error "function defined for this type already!} Note that although \texttt{par \$T} (and also \texttt{\$T}) only \emph{matches} fixed type-insts, it does not mean that the type-inst variable \texttt{\$T} must be \emph{bound} to a fixed type-inst. For example, with these variables and predicate: \begin{verbatim} par int: pi; var int: vi; predicate p(par $T: x, $T: y); \end{verbatim} the first two of the following are acceptable, but the last two are errors: \begin{verbatim} constraint p(pi, pi); % ok: $T bound to 'par int' constraint p(pi, vi); % ok: $T bound to 'var int' constraint p(vi, pi); % error constraint p(vi, vi); % error \end{verbatim} } \subsubsection{Local Variables} Local variables in operation bodies are introduced using let expressions. For example, the predicate \texttt{have\n{}common\n{}divisor} takes two integer values and checks whether they have a common divisor greater than one: \begin{verbatim} predicate have_common_divisor(int: A, int: B) = let { var 2..min(A,B): C; } in A mod C = 0 /\ B mod C = 0; \end{verbatim} However, as Section~\ref{Let Expressions} explained, because \texttt{C} is not defined, this predicate cannot be called in a negative context. The following is a version that could be called in a negative context: \begin{verbatim} predicate have_common_divisor(int: A, int: B) = exists(C in 2..min(A,B)) (A mod C = 0 /\ B mod C = 0); \end{verbatim} %===========================================================================% \section{Annotations} \label{Annotations} %===========================================================================% Annotations---values of the \texttt{ann} type---allow a modeller to specify non-declarative and solver-specific information that is beyond the core language. Annotations do not change the meaning of a model, however, only how it is solved. Annotations can be attached to variables (on their declarations), expresssions, type-inst synonyms, enum items, solve items and on user defined operations. They have the following syntax: %\comment{pjs}{ %What exactly do they mean? In:\\ % \indent\texttt{strength(24.0) :: forall(i in 1..n) x[i] >= 0}\\ %do I get the penalty of 24 if at least one \texttt{x[i] >= 0} is not satisfied, %do I get a penalty of 24 for each one that is not satisfied?\\ %} \begin{productions} \RuleAnnotations \\ \RuleAnnotation \end{productions} For example: \begin{verbatim} int: x::foo; x = (3 + 4)::bar("a", 9)::baz("b"); solve :: blah(4) minimize x; \end{verbatim} The types of the argument expressions must match the argument types of the declared annotation. Unlike user-defined predicates and functions, annotations cannot be overloaded. \Rationale{There is no particular strong reason for this, it just seemed to make things simpler.} Annotation signatures can contain type-inst variables. The order and nesting of annotations do not matter. For the expression case it can be helpful to view the annotation connector \texttt{'::'} as an overloaded operator: \begin{verbatim} ann: '::'(any $T: e, ann: a); % associative ann: '::'(ann: a, ann: b); % associative + commutative \end{verbatim} Both operators are associative, the second is commutative. This means that the following expressions are all equivalent: \begin{verbatim} e :: a :: b e :: b :: a (e :: a) :: b (e :: b) :: a e :: (a :: b) e :: (b :: a) \end{verbatim} This property also applies to annotations on solve items and variable declaration items. \Rationale{This property make things simple, as it allows all nested combinations of annotations to be treated as if they are flat, thus avoiding the need to determine what is the meaning of an annotated annotation. It also makes the MiniZinc abstract syntax tree simpler by avoiding the need to represent nesting.} % The Standard Annotations bit is currently commented out. %Zinc's built-in annotations are listed in Appendix~\ref{Standard %Annotations}. Moreover, an implementation is likely to define a number of %its own annotations for a variety of purposes. %===========================================================================% \section{Partiality} \label{Partiality} %===========================================================================% The presence of constrained type-insts in MiniZinc means that various operations are potentially \emph{partial}, i.e.~not clearly defined for all possible inputs. For example, what happens if a function expecting a positive argument is passed a negative argument? What happens if a variable is assigned a value that does not satisfy its type-inst constraints? What happens if an array index is out of bounds? This section describes what happens in all these cases. % \pjs{This is not what seems to happen in the current MiniZinc!} In general, cases involving fixed values that do not satisfy constraints lead to run-time aborts. \Rationale{Our experience shows that if a fixed value fails a constraint, it is almost certainly due to a programming error. Furthermore, these cases are easy for an implementation to check.} But cases involving unfixed values vary, as we will see. \Rationale{The best thing to do for unfixed values varies from case to case. Also, it is difficult to check constraints on unfixed values, particularly because during search a decision variable might become fixed and then backtracking will cause this value to be reverted, in which case aborting is a bad idea.} % XXX PARTIAL: as described, this static matching turned out to be a bad idea -- % it was not smart enough, and so clearly valid models were rejected, and % making it smarter is a slippery slope -- there are lots of cases, handling % all of them is difficult, and ones that aren't handled lead to very % confusing error messages for users. See additional "XXX PARTIAL" marks % below also. % %%-----------------------------------------------------------------------------% %\subsection{Static Matching} %%-----------------------------------------------------------------------------% %Before describing the cases, we need to define the notion of %\emph{static matching}. % %A type-inst expression \emph{statically matches} another iff one of the %following is true. %\begin{itemize} %\item % They are identical identifiers (ignoring \texttt{par} and \texttt{var} % prefixes). For example, if we have these: %\begin{verbatim} % type Pos = (int: x where x > 0); % type Pos2 = Pos; % set of int: s135 = {1, 3, 5}; % enum C = {R, G, B}; %\end{verbatim} % then we have the following matches and non-matches. %\begin{verbatim} % Pos Pos % match % par s135 var s135 % match % C par C % match % Pos Pos2 % no match: not synt. identical %\end{verbatim} % %\item % They are both range type-insts that contain only scalar literals and % function calls, and they are syntactically identical (ignoring % differences in whitespace, parentheses, annotations, and \texttt{par} % and \texttt{var} prefixes). For example: %\begin{verbatim} % var 1..5 1..5 % match % par m..n+1 m..(n + 1)::foo % match % 1..5 1..4+1 % no match: not synt. identical % 1..f([1,2]) 1..f([1,2]) % no match: '[1,2]' is not scalar %\end{verbatim} % %\item % They are both set expression type-insts that involve only scalar % literals and function calls, and they are syntactically identical % (ignoring differences in whitespace, parentheses, annotations, and % \texttt{par} and \texttt{var} prefixes). For example: %\begin{verbatim} % {1,3,5} par {1,3,5} % match % {1,f(2::a),5} {1,f(2::a)} % match % {1,3,5} {5,3,1} % no match: not synt. identical %\end{verbatim} %\end{itemize} % %We now extend this notion to cover expressions. An expression, \texttt{E}, %\emph{statically matches} a type-inst expression, \texttt{TIE}, iff it has an %\emph{inferred type-inst expression}, \texttt{InfTIE}, and \texttt{InfTIE} %statically matches \texttt{TIE}. The following expressions have inferred %type-inst expressions. % %\begin{itemize} %\item % If \texttt{E} is an identifier expression, and the identifier is that of a % variable, the inferred type-inst expression is the one from the variable's % declaration. For example, if we have this: %\begin{verbatim} % var Pos: p; %\end{verbatim} % then the inferred type-inst expression of the expression \texttt{p} is % \texttt{var Pos}. % %\item % If \texttt{E} is an array access expression where the array expression has % an inferred type-inst expression \texttt{array[IndexTIE] of ElemTIE}, the % inferred type-inst expression is \texttt{ElemTIE}. For example, if we have % this: %\begin{verbatim} % array[1..3] of var Pos: a; %\end{verbatim} % then the expression \texttt{a[1]} has the inferred type-inst expression % \texttt{var Pos}. % %\item % If \texttt{E} is a tuple access expression where the tuple expression has % an inferred type-inst expression \texttt{tuple(TIE1, TIE2, ...)}, the % inferred type-inst expression is \texttt{TIEn} for the selected \texttt{n}. % For example, if we have this: %\begin{verbatim} % tuple(Pos, var int): t; %\end{verbatim} % then the expression \texttt{t.1} has the inferred type-inst expression % \texttt{Pos}. % %\item % If \texttt{E} is a record access expression where the record expression has % an inferred type-inst expression \texttt{record(TIE1:x1, TIE2:x2, ...)}, % the inferred type-inst expression is \texttt{TIEn} for the selected % \texttt{n}. %\end{itemize} % %Note that all variables are declared using a type-inst expression, with one %exception: generator variables. For those, we determine a declaration %type-inst expression from the generator expression, \texttt{GE}, (ignoring any %surrounding set-to-array coercion) using the following rules. %\begin{itemize} %\item % If \texttt{GE} is an identifier of a type-inst expression (e.g.~the name % of a flat enum), the inferred type-inst expression is that same % identifier. %\begin{verbatim} % type t135 = {1,3,5}; % { i | i in t135 } % i's type-inst expression: t135 % enum C = {R, G, B}; % { i | i in C } % i's type-inst expression: C %\end{verbatim} % %\item % If \texttt{GE} is a set identifier, set literal or range expression, the % inferred type-inst expression is the corresponding set expression % type-inst expression. %\begin{verbatim} % set of int: s135 = {1,3,5}; % { i | i in s135 } % i's type-inst expression: s135 % { i | i in 1..5 } % i's type-inst expression: 1..5 % { i | i in {1,3,5::a} } % i's type-inst expression: {1,3,5::a} %\end{verbatim} % %\item % Otherwise, the inferred type-inst expression is the appropriate % unconstrained one. For example: %\begin{verbatim} % { i | i in [1,3,5] } % i's type-inst expression: int %\end{verbatim} %\end{itemize} % %An expression that statically matches a type-inst expression is guaranteed %to satisfy its constraints at run-time. The following sections will show %that static matching is used to guarantee that some potentially partial %cases are actually total. This guarantee is conservative---there are many %expressions that do not statically match a type-inst expression, but would %satisfy its constraint at run-time. % %\Rationale{The static matching rules provide a balance between %ease-of-implementation and ease-of-use. As described, static matching is %easy to implement; in particular, it does not require any compile-time %expression evaluation, which would be required if sub-ranges had to be %detected, for example. But they also cover most cases that occur in %practice; we have seen that modellers almost always use type-inst synonyms %for complex constrained type-insts, and range type-insts are the other %common case. For the cases that static matching does not cover, simple %workarounds usually exist, such as introducing an intermediate variable with %an appropriate type-inst expression.} % %The matching rules may be expanded in the future to make them less %conservative if they are too restrictive. %-----------------------------------------------------------------------------% \subsection{Partial Assignments} %-----------------------------------------------------------------------------% The first operation involving partiality is assignment. There are four distinct cases for assignments. \begin{itemize} \item A value assigned to a fixed, constrained global variable is checked at run-time; if the assigned value does not satisfy its constraints, it is a run-time error. In other words, this: \begin{verbatim} 1..5: x = 3; \end{verbatim} is equivalent to this: \begin{verbatim} int: x = 3; constraint assert(x in 1..5, "assignment to global parameter 'x' failed") \end{verbatim} \item A value assigned to an unfixed, constrained global variable makes the assignment act like a constraint; if the assigned value does not satisfy the variable's constraints, it causes a run-time model failure. In other words, this: \begin{verbatim} var 1..5: x = 3; \end{verbatim} is equivalent to this: \begin{verbatim} var int: x = 3; constraint x in 1..5; \end{verbatim} \Rationale{This behaviour is easy to understand and easy to implement.} \item A value assigned to a fixed, constrained let-local variable is checked at run-time; if the assigned value does not satisfy its constraints, it is a run-time error. In other words, this: \begin{verbatim} let { 1..5: x = 3; } in x+1 \end{verbatim} is equivalent to this: \begin{verbatim} let { int: x = 3; } in assert(x in 1..5, "assignment to let parameter 'x' failed", x+1) \end{verbatim} % XXX PARTIAL: this was specified when syntactic matching looked like a good % idea. For the moment, allowing them to fail seems like a better idea. % %\item % A value assigned to an unfixed, constrained let-local variable is % checked at compile-time; if the assigned value does not statically % match the variable's constraint, it is a compile-time error. In other % words, something like this is not allowed: %\begin{verbatim} % let { var 1..5: x = 3 } in x+1 %\end{verbatim} % because \texttt{3} does not statically match \texttt{var 1..5}. % \Rationale{This is because this case is very uncommon, and implementing % ``failure'' sensibly is not easy. This is also the case that is most % likely to cause a modeller problems, as it can be difficult to introduce % an intermediate variable with the appropriate type-inst expression, % especially if the let is inside a predicate/function.} \item A value assigned to an unfixed, constrained let-local variable makes the assignment act like a constraint; if the assigned value does not statically match the variable's constraint at run-time it fails, and the failure ``bubbles up'' to the nearest enclosing Boolean scope, where it is interpreted as \texttt{false}. \Rationale{This behaviour is consistent with assignments to global variables.} \end{itemize} Note that in cases where a value is partly fixed and partly unfixed, e.g.~some tuples, the different elements are checked according to the different cases, and fixed elements are checked before unfixed elements. For example: \begin{verbatim} u = [ let { var 1..5: x = 6} in x, let { par 1..5: y = 6; } in y) ]; \end{verbatim} This causes a run-time abort, because the second, fixed element is checked before the first, unfixed element. This ordering is true for the cases in the following sections as well. \Rationale{This ensures that failures cannot mask aborts, which seems desirable.} %-----------------------------------------------------------------------------% \subsection{Partial Predicate/Function and Annotation Arguments} %-----------------------------------------------------------------------------% The second kind of operation involving partiality is calls and annotations. % The behaviour for these operations is simple: constraints on arguments are % ignored. % % \Rationale{This is easy to implement and easy to understand. It is also % justifiable in the sense that predicate/function/annotation arguments are % values that are passed in from elsewhere; if those values are to be % constrained, that could be done earlier. (In comparison, when a variable % with a constrained type-inst is declared, any assigned value must clearly % respect that constraint.)} The semantics is similar to assignments: fixed arguments that fail their constraints will cause aborts, and unfixed arguments that fail their constraints will cause failure, which bubbles up to the nearest enclosing Boolean scope. % XXX PARTIAL: this text is from when syntactic checking seemed like a good % idea. Now just ignoring the argument constraints seems better. % %There are two distinct cases. % %\begin{itemize} %\item % Each actual argument in a predicate/function call or annotation that % corresponds to a fixed, constrained formal argument is checked at % run-time; if the actual argument value does not satisfy the formal % argument's constraints, it is a run-time error. % % Similarly, the return value of a function with a constrained return % type-inst expression is checked at run-time; if the return value does % not satisfy the return constraints, it is a run-time error. % % In other words, this: %\begin{verbatim} % function 2..6: f(1..5: x) = x+1; %\end{verbatim} % is equivalent to this: %\begin{verbatim} % predicate f(int: x) = % assert(x in 1..5, "argument 'x' of 'f' failed", % assert(x+1 in 2..6, "return value of 'f' failed", x+1)); %\end{verbatim} % %\item % Each actual argument in a predicate/function call or annotation that % corresponds to an unfixed, formal argument is checked at compile-time; % if the actual argument value does not statically match the formal % argument's type-inst expression, it is a compile-time error. For % example: %\begin{verbatim} % predicate q(var 1..5: x) = x > 0; % var 1..5: i = 3; % constraint q(3); % compile-time error % constraint q(i); % ok %\end{verbatim} % \Rationale{This fits with the way modellers tend to use partial % arguments, which is in a sub-type style rather than a constraining % style. Furthermore, implementing failure in this case is difficult.} %\end{itemize} %-----------------------------------------------------------------------------% \subsection{Partial Array Accesses} %-----------------------------------------------------------------------------% The third kind of operation involving partiality is array access. There are two distinct cases. \begin{itemize} \item A fixed value used as an array index is checked at run-time; if the index value is not in the index set of the array, it is a run-time error. \item An unfixed value used as an array index makes the access act like a constraint; if the access fails at run-time, the failure ``bubbles up'' to the nearest enclosing Boolean scope, where it is interpreted as \texttt{false}. For example: \begin{verbatim} array[1..3] of int: a = [1,2,3]; var int: i; constraint (a[i] + 3) > 10 \/ i = 99; \end{verbatim} Here the array access fails, so the failure bubbles up to the disjunction, and \texttt{i} is constrained to be 99. \Rationale{Unlike predicate/function calls, modellers in practice sometimes do use array accesses that can fail. In such cases, the ``bubbling up'' behaviour is a reasonable one.} \end{itemize} \appendix %=============================================================================% \clearpage \section{Built-in Operations} \label{builtins} %=============================================================================% This appendix lists built-in operators, functions and predicates. They may be implemented as true built-ins, or in libraries that are automatically imported for all models. Many of them are overloaded. Operator names are written within single quotes when used in type signatures, e.g.~\verb+bool: '\/'(bool, bool)+. We use the syntax \texttt{TI: f(TI1,...,TIn)} to represent an operation named \texttt{f} that takes arguments with type-insts \texttt{TI,...,TIn} and returns a value with type-inst \texttt{TI}. This is slightly more compact than the usual MiniZinc syntax, in that it omits argument names. %\newcommand{\builtin}{\hspace{-8mm}$\bullet$} \newcommand{\builtin}{\noindent} %---------------------------------------------------------------------------% \subsection{Comparison Operations} %---------------------------------------------------------------------------% \builtin{} Less than. Other comparisons are similar: greater than (\texttt{>}), less than or equal (\texttt{<=}), greater than or equal (\texttt{>=}), equality (\texttt{==}, \texttt{=}), and disequality (\texttt{!=}). % \pjs{Check use of any here!} \begin{verbatim} bool: '<'( $T, $T) var bool: '<'(var $T, var $T) \end{verbatim} %---------------------------------------------------------------------------% \subsection{Arithmetic Operations} %---------------------------------------------------------------------------% \builtin{} Addition. Other numeric operations are similar: subtraction (\texttt{-}), and multiplication (\texttt{*}). \begin{verbatim} int: '+'( int, int) var int: '+'(var int, var int) float: '+'( float, float) var float: '+'(var float, var float) \end{verbatim} \builtin{} Unary minus. Unary plus (\texttt{+}) is similar. \begin{verbatim} int: '-'( int) var int: '-'(var int) float: '-'( float) var float: '-'(var float) \end{verbatim} \builtin{} Integer and floating-point division and modulo. \begin{verbatim} int: 'div'( int, int) var int: 'div'(var int, var int) int: 'mod'( int, int) var int: 'mod'(var int, var int) float: '/' ( float, float) var float: '/' (var float, var float) \end{verbatim} The result of the modulo operation, if non-zero, always has the same sign as its first operand. The integer division and modulo operations are connected by the following identity: \begin{verbatim} x = (x div y) * y + (x mod y) \end{verbatim} Some illustrative examples: \begin{verbatim} 7 div 4 = 1 7 mod 4 = 3 -7 div 4 = -1 -7 mod 4 = -3 7 div -4 = -1 7 mod -4 = 3 -7 div -4 = 1 -7 mod -4 = -3 \end{verbatim} \builtin{} Sum multiple numbers. % Unrolled using \texttt{+}. Product (\texttt{product}) is similar. Note that the sum of an empty array is 0, and the product of an empty array is 1. \begin{verbatim} int: sum(array[$T] of int ) var int: sum(array[$T] of var int ) float: sum(array[$T] of float) var float: sum(array[$T] of var float) \end{verbatim} \builtin{} Minimum of two values; maximum (\texttt{max}) is similar. \begin{verbatim} any $T: min(any $T, any $T ) \end{verbatim} \builtin{} Minimum of an array of values; maximum (\texttt{max}) is similar. Aborts if the array is empty. \begin{verbatim} any $U: min(array[$T] of any $U) \end{verbatim} \builtin{} Minimum of a fixed set; maximum (\texttt{max}) is similar. Aborts if the set is empty. \begin{verbatim} $T: min(set of $T) \end{verbatim} \builtin{} Absolute value of a number. \begin{verbatim} int: abs( int) var int: abs(var int) float: abs( float) var float: abs(var float) \end{verbatim} \builtin{} Square root of a float. Aborts if argument is negative. \begin{verbatim} float: sqrt( float) var float: sqrt(var float) \end{verbatim} \builtin{} Power operator. E.g.~\texttt{pow(2, 5)} gives \texttt{32}. \begin{verbatim} int: pow(int, int) float: pow(float, float) \end{verbatim} % We should also have: % var float: pow(var float, int) \builtin{} Natural exponent. \begin{verbatim} float: exp(float) var float: exp(var float) \end{verbatim} \builtin{} Natural logarithm. Logarithm to base 10 (\texttt{log10}) and logarithm to base 2 (\texttt{log2}) are similar. \begin{verbatim} float: ln(float) var float: ln(var float) \end{verbatim} \builtin{} General logarithm; the first argument is the base. \begin{verbatim} float: log(float, float) \end{verbatim} \builtin{} Sine.

Other logical operations are similar: disjunction (\verb+\/+) reverse implication (\texttt{<-}), forward implication (\texttt{->}), bi-implication (\texttt{<->}), exclusive disjunction (\texttt{xor}), logical negation (\texttt{not}). Note that the implication operators are not written using \texttt{=>}, \texttt{<=} and \texttt{<=>} as is the case in some languages. This allows \texttt{<=} to instead represent ``less than or equal''. \begin{verbatim} bool: '/\'( bool, bool) var bool: '/\'(var bool, var bool) \end{verbatim} \builtin{} Universal quantification. Existential quantification (\texttt{exists}) is similar. Note that, when applied to an empty list, \texttt{forall} returns \texttt{true}, and \texttt{exists} returns \texttt{false}. \begin{verbatim} bool: forall(array[$T] of bool) var bool: forall(array[$T] of var bool) \end{verbatim} \builtin{} N-ary exclusive disjunction. N-ary bi-implication (\texttt{iffall}) is similar, with \texttt{true} instead of \texttt{false}. \begin{verbatim} bool: xorall(array[$T] of bool: bs) = foldl('xor', false, bs) var bool: xorall(array[$T] of var bool: bs) = foldl('xor', false, bs) \end{verbatim} %---------------------------------------------------------------------------% \subsection{Set Operations} %---------------------------------------------------------------------------% \builtin{} Set membership. \begin{verbatim} bool: 'in'( $T, set of $T ) var bool: 'in'(var int, var set of int) \end{verbatim} \builtin{} Non-strict subset. Non-strict superset (\texttt{superset}) is similar. \begin{verbatim} bool: 'subset'( set of $T , set of $T ) var bool: 'subset'(var set of int, var set of int) \end{verbatim} \builtin{} Set union. Other set operations are similar: intersection (\texttt{intersect}), difference (\texttt{diff}), symmetric difference (\texttt{symdiff}). \begin{verbatim} set of $T: 'union'( set of $T, set of $T ) var set of int: 'union'(var set of int, var set of int ) \end{verbatim} \builtin{} Set range. If the first argument is larger than the second (e.g.~\texttt{1..0}), it returns the empty set. \begin{verbatim} set of int: '..'(int, int) \end{verbatim} \builtin{} Cardinality of a set. \begin{verbatim} int: card( set of $T) var int: card(var set of int) \end{verbatim} \builtin{} Union of an array of sets. %Unrolled with \texttt{union}. Intersection of multiple sets (\texttt{array\n{}intersect}) is similar. \begin{verbatim} set of $U: array_union(array[$T] of set of $U) var set of int: array_union(array[$T] of var set of int) \end{verbatim} \ignore{ \builtin{} Power set. \begin{verbatim} set of set of $T: powerset(set of $T) \end{verbatim} \builtin{} Cartesian product of sets.

Returns the list (integer-indexed array) containing all elements of the first argument followed by all elements of the second argument, with elements occurring in the same order as in the arguments. The resulting indices are in the range \texttt{1..n}, where \texttt{n} is the sum of the lengths of the arguments. \Rationale{This allows list-like arrays to be concatenated naturally and avoids problems with overlapping indices. The resulting indices are consistent with those of implicitly indexed array literals.} Note that \texttt{'++'} also performs string concatenation. \begin{verbatim} array[int] of any $T: '++'(array[int] of any $T, array[int] of any $T) \end{verbatim} \ignore{ \builtin{} Array merge. Does not change any indices. If any index is repeated in the result, it is a run-time error. Note that it may result in an interleaving of the elements, e.g.~the merge of \texttt{[1:1, 3:3]} and \texttt{[2:2, 4:4]} is \texttt{[1:1, 2:2, 3:3, 4:4]}. \begin{verbatim} array[$T] of any $U: merge(array[$T] of any $U, array[$T] of any $U) \end{verbatim} } \builtin{} Index sets of arrays. If the argument is a literal, returns \texttt{1..n} where \texttt{n} is the (sub-)array length. Otherwise, returns the declared or inferred index set.

Converts the integer given by the second argument into a string right justified by the number of characters given by the first argument, or left justified if that argument is negative. If the second argument is not fixed, the form of the string is implementation-dependent. \begin{verbatim} string: show_int(int, var int); \end{verbatim} \builtin{} Formatted to-string conversion for floats. Converts the float given by the third argument into a string right justified by the number of characters given by the first argument, or left justified if that argument is negative.

It is easier to implement, and it can be flattened into FlatZinc in a straightforward manner. For more details on the goals of MiniZinc and FlatZinc, please read \CommonMiniZincPaperTitleAndAuthors{}. This section defines MiniZinc by describing the features from Zinc that it does not support. The two languages have identical grammars, although various syntactically-correct constructs are not valid in MiniZinc programs, and should be rejected by post-parsing checks. \Rationale{In the past, the two languages did have distinct grammars, but combining them makes this document much simpler. It also makes the implementation of MiniZinc a little simpler. It can also allow for better error messages if a Zinc-only feature is used in a MiniZinc program; for example, if an enum item appears in a MiniZinc program, instead of a syntax error such as ``syntax error at \texttt{enum}'', a more helpful error such as ``MiniZinc does not allow enum items'' can be emitted. And it allows Zinc features to be added to MiniZinc more easily later on, should we desire.} %---------------------------------------------------------------------------% \subsection{Items} %---------------------------------------------------------------------------% MiniZinc has the following restrictions on items. \begin{itemize} \item Type-inst synonym items are not supported. \item Enum items are not supported. \item User-defined function items are not supported. \item \CommonSolveMinMaxExprTypeInst{} \end{itemize} %---------------------------------------------------------------------------% \subsection{Type-insts and Expressions} %---------------------------------------------------------------------------% MiniZinc has the following restrictions on type-insts and expressions. \begin{itemize} \item Sets can only contain Booleans, integers, and floats. Sets of integers may be fixed or unfixed; other sets must be fixed. \item Arrays must have indices that are contiguous integer ranges (e.g.~\texttt{0..3}, \texttt{10..12}, or the name of a set variable assigned in the model with a range value), or a tuple of contiguous integer ranges. Furthermore, MiniZinc arrays must be declared with index types that are explicit ranges, or variables that are assigned a range value. Because these types are finite, only explicitly-indexed array variables can be declared in MiniZinc. The one exception is that implicitly-indexed arrays are allowed as arguments to predicates and annotations. \item Arrays can only contain Booleans, integers, floats or sets of integers (all fixed or unfixed), or fixed sets of Booleans or floats, or fixed strings. Arrays-of-arrays are not supported. \item Indexed array literals and comprehensions are not supported. \item Tuples can only be used as array indices, and must contain integers, and must be fixed. Furthermore, neither tuple literals nor tuple accesses are supported. \item Records are not supported. Therefore, neither record literals nor record accesses are supported. Furthermore, there are no local namespaces for record field names. \item Enums are not supported, including in data files. Therefore, case expressions are not supported. Furthermore, there are no local namespaces for (non-flat) enum field names. \item The language is entirely first-order; no higher-order types are supported, operation type-inst expressions are not supported, and operations cannot be used as values. \item Arbitrarily constrained type-insts are not supported. \item Implicit type coercions (e.g.~int-to-float, set-to-array) are not supported, with one exception: set-to-array coercions are allowed in comprehension generators. This allows sets to be used as generator expressions, which is very convenient. However, explicit type coercions are supported (e.g.~\texttt{int2float}), as are implicit inst coercions (e.g.~par-int-to-var-int). \item Type-inst variables are not supported in user-defined predicates and functions. However, many of the built-in operations, e.g.~\texttt{show}, have signatures that feature type-inst variables, and they work with all valid matching MiniZinc types. \end{itemize} %---------------------------------------------------------------------------% \subsection{Built-in Operations} %---------------------------------------------------------------------------% MiniZinc has restrictions on built-in operations. \begin{itemize} \item The comparison operators are not supported for arrays. That is, only the following signatures of `\texttt{<}' are supported (and likewise for the other comparison operators): \begin{verbatim} bool: '<'( int, int) var bool: '<'(var int, var int) bool: '<'( float, float) var bool: '<'(var float, var float) bool: '<'( bool, bool) var bool: '<'(var bool, var bool) bool: '<'( string, string) bool: '<'( set of int, set of int) bool: '<'( set of bool, set of bool) bool: '<'( set of float, set of float) var bool: '<'(var set of int, var set of int) \end{verbatim} \item Only the following signatures of \texttt{min} are supported (and likewise for \texttt{max}): \begin{verbatim} int: min( int, int) var int: min(var int, var int) float: min( float, float) var float: min(var float, var float) int: min(array[int] of int) var int: min(array[int] of var int) float: min(array[int] of float) var float: min(array[int] of var float) int: min(set of int) float: min(set of float) \end{verbatim} \item Only the following signatures of `\texttt{in}' are supported: \begin{verbatim} bool: 'in'( int, set of int) bool: 'in'( bool, set of bool) bool: 'in'( float, set of float) var bool: 'in'(var int, var set of int) \end{verbatim} \item For \texttt{array1d}, \texttt{array2d}, etc., the set arguments must be contiguous integer sets, otherwise it is a run-time error. \item % XXX: ones that could be in MiniZinc: concat, head/last/tail, % foldl/foldr (which would require lifting the "entirely % first-order" restriction above). The following built-in operations are not supported: % (and why not?) \texttt{powerset}, % set-of-set \texttt{cartesian\n{}product}, % tuples \texttt{concat}, % (no reason) \texttt{head}, \texttt{last}, \texttt{tail}, % (no reason) \texttt{condense}, \texttt{condense\n{}int\n{}index}, % array-of-arrays \texttt{foldl}, \texttt{foldr}. % (no reason) \iffalse \item The following built-in annotations are not supported: \texttt{tree\n{}search}. \fi \end{itemize} \iffalse % [Seb] % The "globals" library files aren't mentioned anywhere else in this document. %-----------------------------------------------------------------------------% \subsection{Other} %-----------------------------------------------------------------------------% MiniZinc has the following other restrictions. \begin{itemize} \item \texttt{globals.mzn} is the equivalent to the Zinc \texttt{globals.zinc} library. \end{itemize} \fi } %=============================================================================% \clearpage \section{Content-types} \label{Content-types} %=============================================================================% %-----------------------------------------------------------------------------% \subsection{`application/x-zinc-output'} \label{x-zinc-output} %-----------------------------------------------------------------------------% The content-type `application/x-zinc-output' defines a text output format for Zinc. The format extends the abstract syntax and semantics given in Section~\ref{Run-time Outcomes}, and is discussed in detail in Section~\ref{Output}. The full syntax is as follows: \begin{productions} \RuleOutput \\ \\ \RuleSolution \\ \\ \RuleOutcomeStrings \\ \\ \RuleComplete \\ \\ \RuleWarnings \\ \\ \RuleMessage \end{productions} \noindent The solution text for each solution must be as described in Section~\ref{Output Items}.

As it runs, each variable's \emph{domain} (the set of values it may take) may be reduced, possibly to a single value. An \emph{instantiation} (sometimes abbreviated to \emph{inst}) describes how fixed or unfixed a variable is at instance-time. At the most basic level, the instantiation system distinguishes between two kinds of variables: \begin{enumerate} \item \emph{Parameters}, whose values are fixed at instance-time (usually written just as ``fixed''). \item \emph{Decision variables} (often abbreviated to \emph{variables}), whose values may be completely unfixed at instance-time, but may become fixed at run-time (indeed, the fixing of decision variables is the whole aim of constraint solving). \end{enumerate} } %-----------------------------------------------------------------------------% \newcommand{\CommonTypeInstDescription}{ Because each variable has both a type and an inst, they are often combined into a single \emph{type-inst}. Type-insts are primarily what we deal with when writing models, rather than types. A variable's type-inst \emph{never changes}. This means a decision variable whose value becomes fixed during model evaluation still has its original type-inst (e.g.~\texttt{var int}), because that was its type-inst at instance-time. Some type-insts can be automatically coerced to another type-inst. For example, if a \texttt{par int} value is used in a context where a \texttt{var int} is expected, it is automatically coerced to a \texttt{var int}. We write this \coerce{\texttt{par int}}{\texttt{var int}}. Also, any type-inst can be considered coercible to itself. } %-----------------------------------------------------------------------------% \newcommand{\CommonIntegersOverview}{ Integers represent integral numbers.

Each model can have at most one output item. If a solution is found and an output item is present, it is used to determine the string to be printed. If a solution is found and no output item is present, the implementation should print all the global variables and their values in a readable format.

0ustar kaolkaolMiniZinc 2 ========================= Installation Instructions ------------------------- These instructions are for compiling and installing MiniZinc 2 from the source distribution. MiniZinc 2 is based on the libminizinc C++ library. In order to compile and install libminizinc you will need the following software: Compilation instructions: ------------------------- Prerequisite software: - cmake - A recent C++ compiler, libminizinc has been tested with recent versions of clang, g++, and Microsoft Visual C++. - The bison and flex parser/lexer generators. These usually come packaged for Linux distributions, and they are part of the Xcode developer tools for Mac OS. On Windows, you can e.g. install them via cygwin. Download the source code from the git repository or uncompress a source archive. Then change into the toplevel directory (the one containing this file). To perform the build: > mkdir build > cd build/ > cmake .. > cmake --build . To install MiniZinc: > cmake --build . --target install This will install MiniZinc in the standard location for you system. In order to change the installation prefix, invoke cmake as follows before invoking cmake --build: > cmake -DCMAKE_INSTALL_PREFIX:PATH= .. Running ------- The build produces the mzn2fzn and solns2out tools. These are drop-in replacements for the MiniZinc 1.6 versions. Add the bin directory in the installation path to your PATH environment variable if necessary, or (if you did not install) add the "build" directory to your PATH. We currently do not provide the minizinc driver program that was part of MiniZinc 1.6 in the source distribution. It is however included in the binary distributions. If you have both MiniZinc 1.6 and 2 installed (and MiniZinc 2.0 occurs on the PATH before 1.6), you can use the old minizinc driver with the new versions of mzn2fzn and solns2out. libminizinc-2.0.11/mzn2doc.cpp0000644000175000017500000002444012646030173014626 0ustar kaolkaol/* -*- mode: C++; c-basic-offset: 2; indent-tabs-mode: nil -*- */ /* * Main authors: * Guido Tack */ /* This Source Code Form is subject to the terms of the Mozilla Public * License, v. 2.0.

Compared to the previous version 1.6, it is a complete re-write of the MiniZinc-to-FlatZinc compiler, based on the new libminizinc C++ library. For installation and compilation instructions please refer to the file INSTALL.txt. Changes from version 1.6 ------------------------ MiniZinc 2.0 contains many new features and is based on a complete rewrite of the MiniZinc-to-FlatZinc compiler. If you are currently using the previous version 1.6, the new tools can be used as drop-in replacements. The generated FlatZinc is compatible with version 1.6, so all FlatZinc solvers should work without changes. ** MiniZinc language changes ** - MiniZinc now supports user-defined functions. Details have been published in the paper "MiniZinc with Functions". Both functions and predicates can be recursive. - MiniZinc now supports option types. Details have been published in the paper "Modelling with Option Types in MiniZinc". - Let expressions have been generalised. They can now contain constraint items in addition to variable declarations. - Array index sets can be declared using arbitrary set expressions as long as they evaluate to contiguous ranges. - The if-then-else expression has been generalised to allow the condition to be a var bool expression (instead of only par bool). - Array and set comprehensions as well as generator calls can now iterate over variables and use var bool where conditions. - Any bool expression can now automatically coerce to an int expression, likewise for int and float. This means that you don't have to write bool2int or int2float in you models any more. - Equality constraints can now be posted between array expressions. - Arbitrary expressions can now be included ("interpolated") into strings, using the syntax "some text \(e) some more text", where e is any expression. It is the same as writing "some text "++show(e)++" some more text". ** New built-in functions ** Array functions: array1d, arrayXd, row, col, has_index, has_element, sort_by, sort, arg_sort, arg_min, arg_max ** New global constraints ** - arg_max, arg_min - arg_sort - k-dimensional diffn - disjunctive - geost - knapsack - network_flow - regular with NFAs - symmetric all different - optional scheduling constraints: alternative, span, disjunctive, cumulative - functional versions of many global constraints ** New tool chain ** - There are a few new builtins that solvers can reimplement, these are listed in the redefinitions-2.0 file. - Include items use a different method for finding included files. Paths are now interpreted as relative to the file that has the include item. That way, the mzn2fzn compiler can be called from a different working directory. - A new tool, mzn2doc, can produce html output from the documentation comments. The MiniZinc distribution contains the documentation for global constraints and builtins generated directly from the library source code. ** Bugs ** If you encounter any problems with MiniZinc, please use the MiniZinc bug tracker at http://www.minizinc.org/trac to report any issues or feature requests.
