Arsalan Modirkhazeni commented,
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...

Arsalan Modirkhazeni commented,
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...

Infeasible constraints: flow_1[110,310,110]
AnsweredI want to implement the new constraint called solenoidality constraint in my Gurobi code and explain it in the following section: set E within {N,N} := B union setof{(i,j) in B} (j,i); set D within...

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...

"out of memory" error for defining variable and constraint
AnsweredThere is a constraint that I should implement in my project which is x[i, j, s, t] + x[j, k, s, t] ) <= 1 for (i, j) in E0 for (j, k) in E0 for (s, t) in D_s_t, for this constraint, I define a vari...
