The reading of data that are used to construct the model is the same. I read data from an Excel file, the latest version has two additional sheets compared to the older. These additional data are u...

Hi Marika, Thank you for your quick reply! Checking both models would be extremely time-consuming as the model has 200k variables and 11k constraints. Maybe I will check when I find some free time....

Thanks Jaromil! Indeed, that makes sense. Best regards, Yaroslav

Hi Jaromil, I just wanted to report to you something odd that I noticed regarding gurobi's performance between pulp and gurobipy. It seems that gurobi's performance is better when using pulp, inste...

Hi Jaromil, Yes, I found which constraints were responsible for infeasibility. By the way, for instance 10 I am not using Lagrangian relaxation as the model is feasible. However, the solver gets st...

Hi Jaromil, Thank you for your reply and the resources provided. Yes, I tried without Lagrangian relaxation but it gives an infeasible solution. That is why I use it actually, to relax some hard co...
