Hi Michel Soares, I apologize for not putting the right instance files. I updated the link with the files containing the models. This is the confguration with Gurobi 11.0.0 Gurobi Optimizer versio...

Hi Michel, Here is the link to the two .lp models which are distinctive by their names. I got from Gurobi the cost function value of the returned solution by the relaxed model which is later not fe...

Hi Riley, In which format do you want to the model ? Do you need access to the python code as well ? Laaziz

Hi Riley, Got it ! I fixed the issue finally as it was a mistake in the indices of one of the constraints of the model. However, I am not sure why Gurobi is saying that a solution for the relaxed m...

Hi Michel, Sure! The following file relax-RAPEC is recorded before calling the optimize() method. The next one is after calling the computeIIS() which means that the model was found being infeasibl...

Model becomes infeasible after relaxation
AnsweredHi all, I have an optimization problem for which I am able to get the optimal solution in which I have binary variables. When I relax the variable to take values between 0 and 1, the model becomes ...

Hi Simran, Actually, I am getting a negative cost function value. In fact, the decision variables are binary so I am not sure why it does not work as I expected. What do you mean by the default low...

Hi Simran, Thank you for your proposition. I tried it but I am facing a KeyError: 'Missing constraint index' issue.Please check out this implementation and let me know what I need to fix.Actually, ...

issue with Model.addGenConstrMax()
AnsweredI have a mathematical model \(P\) for which I optimize two cost functions say \(F_1\) and \(F_2\) subject to a set of constraints. In \(F_2\), I want it to be included only when its expression vio...
