Thank you Simran.

My ultimate goal is to produce a graph like that. Is this possible through the log file or callbacks? or that is not something that we can always obtain? Kind regardsIason

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...

Another log that I get sometimes isIteration Objective Primal Inf. Dual Inf. Time 12317 9.4324848e+06 5.097459e+02 5.788624e+08 5s 16557 1.1036289e+07 4.582912...

After restarting python this stopped happening. Thanks Mattias, it could be a bug or something else.Kind regardsIason

one thing that I suspect is that my model is within a function that I call in the below code: subproblem = SP_define(K,number_of_nodes,nodes,links,arcs,arcs_numeric,capacities, cap...

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...

Thanks Mario.

Another way just for future reference is: where subproblem is the name of the model. # Define the prefix to match your variable naming pattern# This should match the variable name pattern used when...

I want to add some context. I am applying the Benders Decomposition algorithm. And I have a Master problem and a Subproblem. It happens depending on my starting point (initial feasible solution) in...
