Member Function Documentation

template<class VA , class VB >
ExecStatus Gecode::Int::Arithmetic::SqrPlusDom< VA, VB >::post ( Home  home,
VA  x0,
VB  x1 
) [inline, static]

Post propagator $x_0\cdot x_0=x_1$.

Definition at line 212 of file sqr.hpp.

template<class VA , class VB >
Actor * Gecode::Int::Arithmetic::SqrPlusDom< VA, VB >::copy ( Space &  home,
bool  share 
) [virtual]

Copy propagator during cloning.

Implements Gecode::Actor.

template<class VA , class VB >
PropCost Gecode::Int::Arithmetic::SqrPlusDom< VA, VB >::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< VA, PC_INT_DOM, VB, PC_INT_DOM >.

Definition at line 231 of file sqr.hpp.

template<class VA , class VB >
ExecStatus Gecode::Int::Arithmetic::SqrPlusDom< VA, VB >::propagate ( Space &  home,
const ModEventDelta &  med 
) [virtual]

Perform propagation.

Implements Gecode::Propagator.
