Detailed Description

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

"Domain consistent" circuit propagator

Propagates domain consistent distinct, checks that the induced variable value graph is stronlgy connected, and prunes too shot cycles.

Requires

Member Function Documentation

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

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 56 of file dom.hpp.

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

Cost function.

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

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

Definition at line 62 of file dom.hpp.

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 71 of file dom.hpp.

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.
