Detailed Description

template<class Val, class A, class B>
class Gecode::Int::Linear::EqBin< Val, A, B >

Propagator for bounds consistent binary linear equality

The type Val can be either long long int or int, defining the numerical precision during propagation. The types A and B give the types of the views.

The propagation condition pc refers to both views.
