Using quadratic constraint(s) with multi-objective function (python)

    What type of license are you using? There is only one version of Gurobi, but certain license types may restrict how large of problems you are able to solve. The \( \texttt{gurobipy} \) pip installation includes such a size-restricted license (which cannot be used in production).

    It could be that Gurobi's presolve handles the single-objective and multi-objective models differently. As a result, it's possible that the presolved multi-objective model has more quadratic terms than allowed by your license.

    I see one of my colleagues has opened a ticket for you in our online support portal to discuss this further.

    Hi Eli,

    I am using online course license that Gurobi offers ( I think this license type has an upper cap of having max 2000 decision variables and 2000 constraints. It's free to use.

    If your could pls confirm that the license type is a limiting factor here.
