Xavier Nodet commented,
Not a direct answer to your question, but are you aware that Gurobi 12 can handle nonlinear models and solve them to global optimality. This webinar presents how to do so in Python, and the documen...

Xavier Nodet commented,
This section of the documentation refers to attributes, not parameters. Attributes are used "for querying and modifying properties of a Gurobi model", while "parameters control the operation of th...

With Multi-Objective Environments, you can specify parameters for each optimisation pass in a multi-objective model. This is described at https://www.gurobi.com/documentation/11.0/refman/additiona...

You mentioned that your solution should be feasible. As stated at e.g. https://docs.gurobi.com/projects/optimizer/en/10.0/reference/java/callback.html#java-method-GRBCallback-useSolution, the value...

Xavier Nodet commented,
Your understanding that "InfUnbdInfo will only take effects after finding the model is infeasible or unbounded" is correct. And you can see that the logs with both InfUnbdInfo values are similar u...

Thanks for the model. I was able to reproduce the issue, and we're looking into this.
