Code: alias (m,n); Positive variables AI(p,m) quantity sold Q(p,m) quanitity produced Equations AMP(p,m) Restriction: AMP(...

Thanks for your answer.

But as I said, Im not confused by receiving a solution that is not optimal. I'm confused by the fact that the best possible solution in the output changes.

best possible - final solution = gap (=optca)
