Hi Pim, Thanks for sharing the code and sorry for getting back longer than I expected. After looking into the code, you have created many redundant constraints. Specifically, cons7 and cons9. Pleas...

Hi Pim, Thanks posting. Let me see if I can help. Let me start with a question: the memory error you encountered (for 365 days) happened during model building, or during model solving? Assuming it ...

Hi Eunseok, I am very happy to hear that you are able to resolve the issue. Thanks you for participating in the forum and sharing the question/issue/and resolution. Best regards,

Hmm. Not sure why my logs are shown in just one-line. You may modify the model, run it from your side, and confirm.

Hi Eunseok, Thanks for sharing your numerical example. It shows this model instance is in the "numerical wonderland". While dealing with non-linear functions (e.g., EXP, LOG,..), a common approach ...

Hi Eunseok, Yes, you can set the values, as you wish, to satisfy that single constraint. This pdf file contains a definition of a "feasible solution". I hope it can clarify your question. Best rega...

Hi Eunseok, Thanks for providing your model and log file. I am able to repeat with similar results. With respect to your questions: 1. "My question is why Gurobi limits the magnitude of gLogTerm_S_...

Hi Eunseok, Thanks for providing your updated model, run details, and log file. I can confirm the execution results are similar on my side. wrt. your "3. Gurobi claims that this model is infeasible...

Hi Eunseok I am happy that you find the post which explains why your bounded variables are shown as "free" in the IIS instance. Now, let us focus on your needs: 1. what to do in presence of an IIS...

Hi Eunseok, My understanding is that you have a different question at this point. Namely why "free was added" to the model while you have modeled them to be bounded. I will recommend you create a d...
