Hi Boyu, Before trying to run in parallel, I recommend testing your models one after the other. They are very small and even sequentially, Gurobi should solve all 48 of them in just a few seconds. ...

Hi Mike, I suppose this is not possible without a proper license. There is no "dummy" or "shallow" Model class for this purpose. To get around using too many licenses, you could just keep the curre...

Hi Buddi, In case you don't have enough memory for both Gurobi and matplotlib at the same time, I recommend cleaning up the Gurobi model after the optimization is finished and you have stored the s...

Hi Parisa, The Cuts parameter controls how many cutting planes are generated and are added to strengthen the LP relaxation. More cuts (Cuts=2 or 3) in the problem also means that solving every sing...

Hi Buddi, Could you please share some more details on this issue? It would be best if you could provide us with a (minimal) reproducible example that we can run ourselves. At the moment, I suppose ...

Hi Lee, Every interface is a wrapper of the C API, so this behavior is the same for all programming languages. See also here: https://www.gurobi.com/documentation/9.0/refman/index.html Cheers,Matthias

Hi Lee, During a parallel optimization, all threads are communicating with each other. This includes new incumbents. They will all be reported to your callback. While your callback is executed, the...

Running Gurobi on a Jenkins server or some other CI implementation is not different than running it locally. You just need to make sure that a valid license is available and accessible from the ser...

Due to license restrictions, this is not possible with an academic license - except if your CI is running locally and can for example access a site license or is within the academic domain.

Hi Ebru, In general, you want to avoid writing a NodeFile at all. You should try to utilize your available memory (RAM) as much as possible and only use the nodefile as a fallback. It doesn't matte...
