◆ NrootPlusDom() [1/2]

template<class Ops , bool minus>
Gecode::Int::Arithmetic::NrootPlusDom< Ops, minus >::NrootPlusDom ( Space & home,
NrootPlusDom< Ops, minus > & p )

Constructor for cloning p.

Definition at line 311 of file nroot.hpp.

◆ NrootPlusDom() [2/2]

template<class Ops , bool minus>
Gecode::Int::Arithmetic::NrootPlusDom< Ops, minus >::NrootPlusDom ( Home home,

Member Function Documentation

◆ copy()

template<class Ops , bool minus>
Actor * Gecode::Int::Arithmetic::NrootPlusDom< Ops, minus >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 318 of file nroot.hpp.

◆ propagate()

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 335 of file nroot.hpp.

◆ cost()

template<class Ops , bool minus>
PropCost Gecode::Int::Arithmetic::NrootPlusDom< Ops, minus >::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 324 of file nroot.hpp.

◆ post()

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

Post propagator.

Definition at line 296 of file nroot.hpp.
