Hi Eylül, I suspect that there is some issue with the Excel file. Could you please try to read your Excel data with some other tool to check whether there aren't any weird encodings/characters pres...

This thread is continued over here. Cheers,Matthias

Hi! Please excuse us for not responding to your first post. Did you follow the instructions about adding cuts? Could you please also share the final statistics of the optimization run? There should...

Hi Zahraa, Gurobi also supports Java, so you don't need to switch your programming language.See here for more information. Cheers,Matthias

Hi Ozgur, Could you elaborate on how and where Gurobi "gets stuck"? Does the execution of your code not proceed beyond the optimize() call? Are you using any callbacks in your code? Thanks,Matthias

Hi Mohammad, There is virtually no limit on how large a model can be. There are models with millions of variables and constraints that are reduced to just a handful during presolving and can be sol...

Hi Yauhen, I just updated our Getting started guide and added how to write multi-line formulas. We're using MathJax, so all common LaTeX commands should work. Concerning your second question: Using...

Hi Yauhen, You could enforce the optimal value from the first objective \(c^*\) as a new constraint when solving for the second objective function. \[\begin{align}\ & \min & d^T x  \\ &\text{s. t.}...

Hmm, this looks like an issue on Pyomo's side. Can you try writing the problem to MPS format and then solving it with Gurobi directly to see whether there is something wrong. Cheers,Matthias

Hi Leandro, I saw that you started a small Twitter discussion around this topic, so I'd like to link this here: https://twitter.com/leandro_cc/status/1248436643461283840 Cheers,Matthias
