 You could also check the Model Attributes, for example, MaxRHS. The threshold for the warning is 1e+09 for rhs, bounds, and obj coefficients. It is 1e+08 for matrix coefficients.But we recommend t...

Hi Josh, Using gurobipy the default lower bounds for the variables are 0, see Model.addMVar().If you change the lower bound for the D variables to -Infinity, the model becomes feasible. Cheers,Marika

Your code is not directly reproducible but so far I cannot see anything suspicious. Could you explain why you think that your code does not find a maximum weighted matching? If you know an optimal ...

Hi Tomáš,Your interpretation is right. In the MIP and MIPSOL callback, the processing of the provided solution is delayed until the next possible point in the solution process, while in the MIPNODE...

You can check the status of the model, see for example this python script

You could set the PoolSearchMode parameter s.t. the MIP search will continue after a feasible solution was found and set the PoolSolutions parameter to a very high value. In the end, you could chec...

Does it really show “nan” or are the x values simply 0? Please note that the default lower bound for all variables created in Gurobi is 0.I would recommend to write and check the LP-file. You can u...

Can you give more details about what exactly is unclear to you?

Yes, we are currently releasing version 13.0. The Python package is one of the first to be updated. The website's Download Center and the ability to generate Version 13 licenses will be available s...

Hi Krisitna,You can directly type the name of the university in the field.Best regards,Marika
