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...

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...

When I start to solve the file from https://drive.google.com/file/d/1sN2f3QfLpuFkjwrBT9knYejXJRosgxp2/view?usp=sharing, I get a different model fingerprint: 0xf11e235e vs 0xbf1c0f3c in your log. T...

Dear Pablo, We're glad to read that NoRel helps on your models, and would be interested in looking at them, if you can share them. Some details about the NoRel heuristic appear at https://...

You mentioned that your solution should be feasible. As stated at e.g. https://www.gurobi.com/documentation/10.0/refman/java_cb_usesolution.html, the value "1e+100" may be returned when the solutio...

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.

Dear Shouyuan, What Jue wrote is correct. Yet, we would be interested in reproducing the issue whereby setting the InfUnbdInfo parameter already changes the path for the first solve. Could you plea...
