Detailed Description

template<class View0, class View1>
class Gecode::Int::Rel::EqDom< View0, View1 >

Binary domain consistent equality propagator.

Uses staging by first performing bounds propagation and only then domain propagation.

Requires 

 #include <gecode/int/rel.hh>

Member Function Documentation

template<class View0 , class View1 >
Actor * Gecode::Int::Rel::EqDom< View0, View1 >::copy ( Space &  home,
bool  share 
) [virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 150 of file eq.hpp.

template<class View0 , class View1 >
PropCost Gecode::Int::Rel::EqDom< View0, View1 >::cost ( const Space &  home,
const ModEventDelta &  med 
) const [virtual]

Cost function.

If a view has been assigned, the cost is low unary. If in stage for bounds propagation, the cost is low binary. Otherwise it is high binary.

Reimplemented from Gecode::MixBinaryPropagator< View0, PC_INT_DOM, View1, PC_INT_DOM >.

Definition at line 156 of file eq.hpp.

template<class View0 , class View1 >
ExecStatus Gecode::Int::Rel::EqDom< View0, View1 >::propagate ( Space &  home,
const ModEventDelta &  med 
) [virtual]

Perform propagation.

Implements Gecode::Propagator.

template<class View0 , class View1 >
ExecStatus Gecode::Int::Rel::EqDom< View0, View1 >::post ( Home  home,
View0  x0,
View1  x1 
) [static]

Post domain consistent propagator $ x_0 = x_1$.
