Member Function Documentation

template<class View >
Actor * Gecode::Int::Arithmetic::SqrtDom< View >::copy ( Space home,
bool  share 
)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 174 of file sqrt.hpp.

template<class View >
ExecStatus Gecode::Int::Arithmetic::SqrtDom< View >::propagate ( Space home,
const ModEventDelta med 
)
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 191 of file sqrt.hpp.

template<class View >
PropCost Gecode::Int::Arithmetic::SqrtDom< View >::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::BinaryPropagator< View, PC_INT_DOM >.

Definition at line 180 of file sqrt.hpp.

template<class View >
ExecStatus Gecode::Int::Arithmetic::SqrtDom< View >::post ( Home  home,
View  x0,
View  x1 
)
inlinestatic

Post propagator $\lfloor\sqrt{x_0}\rfloor=x_1$.

Definition at line 155 of file sqrt.hpp.
