Detailed Description

template<class Val, class View>
class Gecode::Int::Linear::DomEq< Val, View >

Propagator for domain consistent n-ary linear equality

The type Val can be either long long int or int, defining the numerical precision during propagation. The types View give the type of the view.

◆ DomEq() [1/2]

template<class Val, class View>
Gecode::Int::Linear::DomEq< Val, View >::DomEq ( Space & home,
DomEq< Val, View > & p )
protected

Constructor for cloning p.

◆ DomEq() [2/2]

template<class Val, class View>
Gecode::Int::Linear::DomEq< Val, View >::DomEq ( Home home,
ViewArray< View > & x,
ViewArray< View > & y,

Member Function Documentation

◆ copy()

template<class Val, class View>
Actor * Gecode::Int::Linear::DomEq< Val, View >::copy ( Space & home)
virtual

Create copy during cloning.

Implements Gecode::Actor.

Definition at line 376 of file int-dom.hpp.

◆ cost()

template<class Val, class View>
PropCost Gecode::Int::Linear::DomEq< Val, View >::cost ( const Space & home,
const ModEventDelta & med ) const
virtual

Cost function.

If in stage for bounds propagation, the cost is low linear. Otherwise it is high crazy.

Reimplemented from Gecode::Int::Linear::Lin< Val, View, View, PC_INT_DOM >.

Definition at line 382 of file int-dom.hpp.

◆ propagate()

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

Perform propagation.

Implements Gecode::Propagator.

Definition at line 391 of file int-dom.hpp.

◆ post()

template<class Val, class View>
ExecStatus Gecode::Int::Linear::DomEq< Val, View >::post ( Home home,
ViewArray< View > & x,
ViewArray< View > & y,
Val c )
static

Post propagator for $\sum_{i=0}^{|x|-1}x_i-\sum_{i=0}^{|y|-1}y_i=c$.
