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

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 122 of file eq.icc.

template<class View0, class View1>
PropCost Gecode::Int::Rel::EqDom< View0, View1 >::cost ( void   )  const [virtual]

Cost function.

If a view has been assigned, the cost is PC_UNARY_LO. If in stage for bounds propagation, the cost is PC_BINARY_LO. Otherwise it is PC_BINARY_HI.

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

ExecStatus Gecode::Int::Rel::EqDom< View0, View1 >::propagate ( Space *  home  )  [virtual]

Perform propagation.

Implements Gecode::Propagator.

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

Post domain-consistent propagator $ x_0 = x_1$.
