 Abstract: The \Same\ constraint takes two sets of variables $X$ and $Z$ such that $|X|=|Z|$ and assigns values to them such that the multiset of values assigned to the variables in $X$ is equal to the multiset of values assigned to the variables in $Z$. In this paper we extend the \Same\ constraint in a GCC-like manner by adding cardinality requirements on the values. That is, for each value we have a lower and upper bound on the number of variables that can be assigned this value. We show an algorithm that achieves arc-consistency for this constraint and a faster algorithm that achieves bound-consistency for a restricted case of it.
