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 43 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 53 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.
