Sorry, we didn't get to this question. Glad some experts were able to help in linear programming - Non-convergence in lexicographic column generation - Operations Research Stack ExchangeCheers, David

You can simply remove the files in  /usr/local/bin/gurobi* /usr/local/bin/grb* Using sudo Cheers, David

That is a lot indeed! Please provide a way for us to reproduce this. Does it happen when you run the MPS file? Or only in your code? Cheers, David

Hi Eman, How much is the time limit exceeded? If it is a lot, can you provide some code for us to run? Cheers, David

However, this method is not yet documented for public API usage. Instead, users typically need to analyze the .lp file manually or reconstruct expressions based on constraint structure. To correc...

Hi Botan, This could be the effects of performance variability: What is performance variability? But a few ingredients are missing from the script: Setting the Seed parameter for every iteration D...

Hi Botan, These runtimes are so very small. Have you tried running the same experiment without solving the model? Also, what version of Gurobi are you using? We resolved a related issue in version ...

Hi Jisoon, You can start with a subset of columns (e.g., the solution from a heuristic), but I'm confused because it sounds like you're starting with all of them.Won't fixing variables affect the d...

Hi Jisoon, How are you generating the variables beforehand, and how are you choosing which ones are set to 0? You need to solve the intermediate RMP to get the duals that are used in the pricing pr...

Hi Alessandra, The syntax is model.getVarByName new_model.getVarByName("x") Of course you only need to get the variables you want to use in the new constraint. Or the ones you want to query solutio...
