Thank you Eli for your response. It was very helpful. P.S: For others that might see this post later, it is important to note the difference between X and x in the above codes.

Hello Sonja,Thanks for your helpful answer. 1. Does a regular for loop in Gurobi act exactly in the same way as when we incorporate it into a constraint? For example, are the below cases exactly th...

Hello Eli, Here is the content of my .ilp file. Obviously, SC[11] is a decimal value and it cannot satisfy R423. It is also not possible to relax SE[11]. At most I can change the value of SE[11] wh...

Dear Eli,I found the problem using the method you suggested. The problem is that SE and consequently SC take float values. While on the right-hand side of constraint5, it only takes integer values....

Thank you Eli, it was modified. Now, constraints 5,6,7 cause the infeasibility.

Dear Eli,Your comment was very helpful. I changed my code and modified the typos of the below code. The error was resolved. However, now constraints 4-7 have made the problem infeasible. Even if I ...

Dear Eli,Thank you very much for your reply. As you mentioned, since the relationship between SC and K in my code is nonlinear and cannot be included as a constraint, I think I have to take one of ...

Thanks again and your explanation was very helpful. However, when I implement the way you mentioned, I get an error saying : TypeError: unhashable type: 'tupledict' That's probably because  i  is a...

Dear Greg,I really appreciate your response. But in order to clear up the problem for myself let me explain a bit more. K is not a decision variable. But, SC, SE and DE are. K is a parameter that d...

Thank you Greg for your response.if you mean to calculate K[SC[i]] in a loop similar to the below code, it leads to the same "power" error. As you can see there is non-integer power in the K equati...
