Eli Towle commented,
Are you using WSL2? If so, have you tried following the instructions for "Using a singlemachine individual Gurobi license" described in the How do I set up Gurobi in WSL2 (Windows Subsystem for Li...

Eli Towle commented,
From the FarkasDual documentation: These attributes are only available when parameter InfUnbdInfo is set to 1. Have you set the InfUnbdInfo parameter to 1?

Eli Towle commented,
Like Xavier mentioned, the MIPGap parameter is what you are trying to set. It is a termination criterion  Gurobi will stop solving a model (or multiobjective step) after reaching the specified re...

Eli Towle commented,
The norm() function is used to set one variable equal to the norm of other variables. This means your constraint must be of the form m.addConstr(y == gp.norm(x, 2)) where: \(\texttt{y}\) is a Var ...

Eli Towle commented,
The norm general constraint was not added until Gurobi version 9.5. Please upgrade your Python version (3.6 is endoflife and not supported by recent versions of Gurobi), then upgrade to the lates...

Eli Towle commented,
1) It looks like gp.GRB.MAXIMIZE is set for all objectives. Is there a way to maximize the first objective, and then to minimize each agent's value of AgentShare? One can multiply by 1, but maybe...

Eli Towle commented,
The documentation for Python's Model.setObjectiveN() describes its usage. For your use case, you should pass the method three arguments: The linear expression to optimize The index of the objectiv...

Eli Towle commented,
Can you please post a minimal, selfcontained code snippet that reproduces those errors? Is it somehow possible to run an additional optimization problem where the groups are defined like in the s...

Eli Towle commented,
1. Gurobi 10.0.3 constructs piecewiselinear approximations of the nonlinear \(cos\) functions. By default, Gurobi 11 does the same. However, you can ask Gurobi 11 to model these nonlinear function...

Eli Towle commented,
The current version of YALMIP does not support solving general nonlinear models with Gurobi. If you are interested in using Gurobi's general constraints through MATLAB, you can use Gurobi's native ...
