Subject:  [Helpglpk] Intersection of two sets is empty 
Date:  Sun, 7 Jul 2013 11:56:28 +0100 (BST) 
Hello everyone, Is it possible to express a condition based on the intersection of two sets, the idea is to express if A[i] intersection A[j] is empty then V[i] = c[j]. i.e {i in I, j in j : A[i] inter A[j] == Empty }: V[i] = c[j]; Any suggestion to do that? Thank you Esma
