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.

◆ EqDom() [1/3]

template<class View0, class View1>
Gecode::Int::Rel::EqDom< View0, View1 >::EqDom ( Space & home,
EqDom< View0, View1 > & p )

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

Constructor for posting.

template<class View0, class View1>
Gecode::Int::Rel::EqDom< View0, View1 >::EqDom ( Space & home,

Member Function Documentation

◆ copy()

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

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 206 of file eq.hpp.

◆ cost()

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 212 of file eq.hpp.

◆ propagate()

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 223 of file eq.hpp.

◆ post()

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$.
