Detailed Description

template<class View, bool shared>
class Gecode::Int::Extensional::Basic< View, shared >

Domain consistent extensional propagator.

This propagator implements a basic extensional propagation algorithm. It is based on GAC2001, and as such it does not fully take into account multidirectionality.

If shared is true, the same view can occur multiply.

Member Function Documentation

template<class View , bool shared>

ExecStatus Gecode::Int::Extensional::Basic< View, shared >::propagate	(	Space &	home,
		const ModEventDelta &	med
	)			[inline, virtual]

Perform propagation.

Implements Gecode::Propagator.

Definition at line 92 of file basic.hpp.

template<class View , bool shared>

PropCost Gecode::Int::Extensional::Basic< View, shared >::cost	(	const Space &	home,
		const ModEventDelta &	med
	)			const [inline, virtual]

Cost function.

If in stage for naive value propagation, the cost is high quadratic. Otherwise it is high cubic.

Reimplemented from Gecode::Int::Extensional::Base< View >.

Definition at line 77 of file basic.hpp.

template<class View , bool shared>

Actor * Gecode::Int::Extensional::Basic< View, shared >::copy	(	Space &	home,
		bool	share
	)			[inline, virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 86 of file basic.hpp.

template<class View , bool shared>

ExecStatus Gecode::Int::Extensional::Basic< View, shared >::post	(	Home	home,
		ViewArray< View > &	x,
		const TupleSet &	t
	)			[inline, static]

Post propagator for views x.
