template<class VA, class VB, class Ops>
Gecode::Int::Arithmetic::PowPlusDom< VA, VB, Ops >::PowPlusDom ( Home home,
VA x0,
VB x1,
const Ops & ops )
inlineprotected

Constructor for posting.

Definition at line 306 of file pow.hpp.

◆ PowPlusDom() [2/2]

template<class VA, class VB, class Ops>
Gecode::Int::Arithmetic::PowPlusDom< VA, VB, Ops >::PowPlusDom ( Space & home,

Member Function Documentation

◆ copy()

template<class VA, class VB, class Ops>
Actor * Gecode::Int::Arithmetic::PowPlusDom< VA, VB, Ops >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 331 of file pow.hpp.

◆ cost()

template<class VA, class VB, class Ops>
PropCost Gecode::Int::Arithmetic::PowPlusDom< VA, VB, Ops >::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 337 of file pow.hpp.

◆ propagate()

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 348 of file pow.hpp.

◆ post()

template<class VA, class VB, class Ops>
ExecStatus Gecode::Int::Arithmetic::PowPlusDom< VA, VB, Ops >::post ( Home home,
VA x0,
VB x1,
Ops ops )
inlinestatic

Post propagator.

Definition at line 312 of file pow.hpp.
