Detailed Description

template<class View>
class Gecode::Int::Rel::NaryEqDom< View >

Constructor & Destructor Documentation

◆ NaryEqDom() [1/2]

template<class View>
Gecode::Int::Rel::NaryEqDom< View >::NaryEqDom ( Space & home,
NaryEqDom< View > & p )
inlineprotected

Constructor for cloning p.

Definition at line 292 of file eq.hpp.

◆ NaryEqDom() [2/2]

template<class View>
Gecode::Int::Rel::NaryEqDom< View >::NaryEqDom ( Home home,
ViewArray< View > & x )

Member Function Documentation

◆ copy()

template<class View>
Actor * Gecode::Int::Rel::NaryEqDom< View >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 297 of file eq.hpp.

◆ cost()

template<class View>
PropCost Gecode::Int::Rel::NaryEqDom< 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 linear. Otherwise it is high linear.

Reimplemented from Gecode::NaryPropagator< View, PC_INT_DOM >.

Definition at line 303 of file eq.hpp.

◆ propagate()

template<class View>
ExecStatus Gecode::Int::Rel::NaryEqDom< View >::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 313 of file eq.hpp.

◆ post()

template<class View>
ExecStatus Gecode::Int::Rel::NaryEqDom< View >::post ( Home home,
ViewArray< View > & x )
static

Post domain consistent propagator $ x_0 = x_1=\ldots =x_{|x|-1}$.
