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.

Requires 

 #include <gecode/int/linear.hh>

Member Function Documentation

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

Create copy during cloning.

Implements Gecode::Actor.

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

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

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

Perform propagation.

Implements Gecode::Propagator.

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

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

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