Detailed Description

template<class Val, class P, class N, PropCond pc>
class Gecode::Int::Linear::Lin< Val, P, N, pc >

Base-class for n-ary linear propagators.

The type Val can be either long long int or int, defining the numerical precision during propagation. Positive views are of type P whereas negative views are of type N.

The propagation condition pc refers to all views.
