Dear Riley, Thank you for your reply. I mean that in the following constraint: s.t. flow_1 {(s,t) in D, i in N: i=s}:     sum{(i,j) in E} x[i,j,s,t] - sum{(j,i) in E} x[j,i,s,t] = pr[s,t]; should w...

This is an ample version of the constraint which is like the following section: s.t. flow_1 {(s,t) in D, i in N: i=s}: sum{(i,j) in E} x[i,j,s,t] - sum{(j,i) in E} x[j,i,s,t] = pr[s,t]; s.t. flow...

Thank you for your comment. It perfectly works.

Thank you for your comment, it works well. However, I have another question that is related to the previous question. I have several constraints related to x an example: I have two constraints on x...
