    Hi Vladimir,

     

    Can you please share your model? I Think I know where the issue is coming from.

     

    Best,

    Hi Vladimir,

     

    I am sorry to say that we did find an issue with PoolObjVal and quadratic or piece-wise linear objectives, the issue has been fixed in the code and the fix will be part of any upcoming release (either technical or mayor), unfortunately we don't have a time frame for that.

    Hello,

    Quite a puzzling issue indeed. I guess this fix has not made it to a release yet. I came across the same problem in a model with a quadratic objective. I'm using Gurobi 9.1.0 through the Pyomo persistent solver interface. 

    Thanks, 
    Nikos

    This issue was fixed last year with the release of Gurobi 9.0.0. Can you verify in the Gurobi log/output that Pyomo is using version 9.1.0 of Gurobi and not an older version?

    That was the problem indeed. Thanks a lot.
