Constructor & Destructor Documentation

◆ NrootDom() [1/2]

template<class Ops>
Gecode::Int::Arithmetic::NrootDom< Ops >::NrootDom ( Space & home,
NrootDom< Ops > & p )
inlineprotected

Constructor for cloning p.

Definition at line 418 of file nroot.hpp.

◆ NrootDom() [2/2]

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

Constructor for posting.

Member Function Documentation

◆ copy()

template<class Ops>
Actor * Gecode::Int::Arithmetic::NrootDom< Ops >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 424 of file nroot.hpp.

◆ propagate()

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 441 of file nroot.hpp.

◆ cost()

template<class Ops>
PropCost Gecode::Int::Arithmetic::NrootDom< 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::BinaryPropagator< IntView, PC_INT_DOM >.

Definition at line 430 of file nroot.hpp.

◆ post()

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

Post propagator.

Definition at line 371 of file nroot.hpp.
