Member Function Documentation

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

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 206 of file sqrt.icc.

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 222 of file sqrt.icc.

template<class View>
PropCost Gecode::Int::Arithmetic::SqrtDom< View >::cost ( ModEventDelta  med  )  const [inline, 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::BinaryPropagator< View, PC_INT_DOM >.

void Gecode::Int::Arithmetic::SqrtDom< View >::post ( Space *  home,
Reflection::VarMap &  vars,
const Reflection::ActorSpec &  spec 
) [inline, static]

Post propagator for specification.

template<class View>
Reflection::ActorSpec Gecode::Int::Arithmetic::SqrtDom< View >::spec ( const Space *  home,
Reflection::VarMap &  m 
) const [inline, virtual]

Specification for this propagator.

Reimplemented from Gecode::Actor.
