[Help-glpk] Intersection of two sets is empty

[esma mehiaoui]

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
