Detailed Description

Extensional constraints support different ways of how the extensionally defined relation between the variables is defined. Examples include specification by a DFA or a table.

A DFA can be defined by a regular expression, for regular expressions see the module MiniModel.

Function Documentation

◆ extensional() [1/4]

void Gecode::extensional ( Home  home,
const IntVarArgs x,
DFA  d,
IntPropLevel  ipl = IPL_DEF 
)

Post domain consistent propagator for extensional constraint described by a DFA.

The elements of x must be a word of the language described by the DFA d.

Throws an exception of type Int::ArgumentSame, if x contains the same unassigned variable multiply. If shared occurences of variables are required, unshare should be used.

Definition at line 47 of file extensional.cpp.

◆ extensional() [2/4]

void Gecode::extensional ( Home  home,
const BoolVarArgs x,
DFA  d,
IntPropLevel  ipl = IPL_DEF 
)

Post domain consistent propagator for extensional constraint described by a DFA.

The elements of x must be a word of the language described by the DFA d.

Throws an exception of type Int::ArgumentSame, if x contains the same unassigned variable multiply. If shared occurences of variables are required, unshare should be used.

Definition at line 57 of file extensional.cpp.

◆ extensional() [3/4]

void Gecode::extensional ( Home  home,
const IntVarArgs x,
const TupleSet t,
IntPropLevel  ipl = IPL_DEF 
)

Post propagator for $x\in t$.

  • Supports domain consistency (ipl = IPL_DOM, default) only.
  • Throws an exception of type Int::ArgumentSizeMismatch, if x and t are of different size.
  • Throws an exception of type Int::NotYetFinalized, if the tuple set t has not been finalized.

Definition at line 67 of file extensional.cpp.

◆ extensional() [4/4]

void Gecode::extensional ( Home  home,
const BoolVarArgs x,
const TupleSet t,
IntPropLevel  ipl = IPL_DEF 
)

Post propagator for $x\in t$.

  • Supports domain consistency (ipl = IPL_DOM, default) only.
  • Throws an exception of type Int::ArgumentSizeMismatch, if x and t are of different size.
  • Throws an exception of type Int::NotYetFinalized, if the tuple set t has not been finalized.
