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

Member Function Documentation

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

Create copy during cloning.

Implements Gecode::Actor.

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 386 of file int-dom.hpp.

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

Perform propagation.

Implements Gecode::Propagator.

ExecStatus Gecode::Int::Linear::DomEq< Val, View >::post ( Home  home,
ViewArray< View > &  x,

)
static

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