Detailed Description

template<class Val, class P, class N>
class Gecode::Int::Linear::Nq< Val, P, N >

Propagator for bounds consistent n-ary linear disequality

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

The propagation condition pc refers to both views.
