Detailed Description

template<class VX, class VY>
class Gecode::Int::Count::GqInt< VX, VY >

Propagator for counting views (greater or equal integer to number of equal views)

Not all combinations of views are possible. The types VX and VY must be either equal, or VY must be ConstIntView, ZeroIntView, or IntSet.
