Hello guys you can ignore my previous post, the time was for parameter setting. My question is now on this run why don't I get the percentile gap per time on the log? I see the below Is there anyt...

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...

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....

Hello guys, I have a model and when I do model.write() the created file contains the binary variables plenty of times and a constraint 2 times. I do not create the variables or the constraint 2 tim...

Hello guys, I am working on the Benders algorithm. I am wondering if I have a problem with a variable x with an upper bound of 1. Does that create a constraint of x<=1 on the solver? Because if tha...

Hello guys, I have a problem that all its extreme rays are 0. Do you have any idea of what could be the case? Can we check if there are numerical issues with a problem solution that produce this re...
