Detailed Description

Propagator for domain consistent n-ary linear equality

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

Constructor & Destructor Documentation

Gecode::Int::Linear::DomEq::DomEq ( Space home,
bool  share,
DomEq p 
) [protected]

Constructor for cloning p.

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

Constructor for creation.

Member Function Documentation

Actor * Gecode::Int::Linear::DomEq::copy ( Space home,
bool  share 
) [virtual]

Create copy during cloning.

Definition at line 380 of file int-dom.hpp.

PropCost Gecode::Int::Linear::DomEq::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.

ExecStatus Gecode::Int::Linear::DomEq::propagate ( Space home,
const ModEventDelta med 
) [virtual]

Perform propagation.

Definition at line 395 of file int-dom.hpp.

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

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