Detailed Description

template<class Val, class A, class B, PropCond pc>
class Gecode::Int::Linear::LinBin< Val, A, B, pc >

Base-class for binary linear propagators.

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.
