Thank you Simran, so on the above cases to get the solution gap can I apply callbacks or the gap is not available before a specific point of the solution? I do not know if I can get the solution ga...

Variable bound
回答済みHello guys, I have an optimization model and It is feasible. It has one variable bound though that if I remove it it makes the problem infeasible without making any other change. Does that make sen...

infeasible model has objective function value
ユーザーの入力を待っています。I am solving a model sequentially and it is feasible in the first iteration. In the second iteration the model becomes infeasible but I get an objective function value when I run subproblem.objVal....

Thanks Kaur. This was the case as I was using the code: for i in ["I","E"]: for r,s in drs.keys(): MPmodel.addGenConstrPWL(Rirs[i,r,s], lRirs[i,r,s], horizPoints, verticalPoints, "log_approxima...
