Detailed Description

template<class View, class Offset>
class Gecode::Int::Circuit::Dom< View, Offset >

"Domain consistent" circuit propagator

Member Function Documentation

◆ copy()

template<class View , class Offset >
Actor * Gecode::Int::Circuit::Dom< View, Offset >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 52 of file dom.hpp.

◆ cost()

template<class View , class Offset >
PropCost Gecode::Int::Circuit::Dom< View, Offset >::cost ( const Space & home,

◆ reschedule()

template<class View , class Offset >
void Gecode::Int::Circuit::Dom< View, Offset >::reschedule ( Space & home)
virtual

Schedule function.

Reimplemented from Gecode::NaryPropagator< View, Int::PC_INT_DOM >.

Definition at line 67 of file dom.hpp.

◆ propagate()

template<class View , class Offset >
ExecStatus Gecode::Int::Circuit::Dom< View, Offset >::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 78 of file dom.hpp.

◆ post()

template<class View , class Offset >
ExecStatus Gecode::Int::Circuit::Dom< View, Offset >::post ( Home home,
ViewArray< View > & x,
Offset & o )
static

Post propagator for circuit on x.
