Hi Joshua, We are definitely looking at the new hardware. As these chips have just been released we also just got the hardware. So far, we don't have a native version of Gurobi for the M1 CPUs and ...

Hi, I would try each of the following parameters on its own first MIPFocus=1Presolve=2Method=2Cuts=1CutPasses=3 to see if there is any improvement in the runtime. I would then probably combine a fe...

Hi, There are different ways of doing this. It depends a bit on how you are creating the constraints and which programming language you use. For example, if you are using Python and you are adding ...

Hi Nicolas, This is probably a problem with the import of the Gurobi Python module. In our examples we do the following: import gurobipy as gpfrom gurobipy import GRB If these lines are present bef...

Hi May, If this is a Free Academic license then the only connection to one of our servers is done when installing the license. Gurobi will not communicate again and cause your license to fail. I wi...

Hi, So what you mean is you not just have one constraint \( \texttt{y=tan(x)} \) but you have \( \texttt{m} \) such constraints? Then why not just add that many and use a for loop around the \( \te...

Hi Vicent, Can you share (if they are not too long) the full log files of these runs? It would be interesting to understand a bit more about the model structure and how Gurobi works on it. Thanks, ...

To be able to use Gurobi with GAMS you need a link license. There are two possibilities: You can use OSIGUROBI. You can add the Gurobi-Link via a paid license to your GAMS installation. You can f...

Hi, Sorry, I don't understand your question. Gurobi can only handle vector type of variables. If you have a variable matrix (like in semidefinite programming) you have to find a way to write this a...

Hi Luca, It is definitely possible to do this, we have other users doing it. We at Gurobi don't have experience with Spark. However, the setup can be a bit tricky. We had another user reporting thi...
