Detailed Description
template<class View>
class Gecode::Set::Channel::ChannelInt< View >
Propagator for channelling between variable-value-dual models
Implements channelling constraints between IntVars and SetVars. For IntVars and SetVars it propagates the constraint .
Can be used to implement the "channelling constraints" for disjoint with cardinalities from "Disjoint, Partition and Intersection Constraints for Set and Multiset Variables" Christian Bessiere, Emmanuel Hebrard, Brahim Hnich, Toby Walsh CP 2004
