I know if I want to make 2 index inequal in ampl I have to use the following term:
s.t. b2{s in S, p in P1, j in D1, i in P1, k in D1, r in R:p!=i}
But if I have to make also j!=k what I have to do? I tried the following options but non of them worked!
s.t. b2{s in S, p in P1, j in D1, i in P1, k in D1, r in R:p!=i , j!=k}
s.t. b2{s in S, p in P1, j in D1, i in P1, k in D1, r in R:p!=i : j!=k}
s.t. b2{s in S, p in P1, j in D1, i in P1, k in D1, r in R:p!=i j!=k}
