The two indicator constraints model.addConstrs((check_v[i]==0) >> (v[i] >= IntFeasTol) for i in range(3))model.addConstrs((check_v[i]==0) >> (absVar[i] >= IntFeasTol) for i in range(3)) make sure t...

Hi Purnima, You can print the objective values as follows for w in range(m.SolCount):    m.Params.SolutionNumber = w   # consider all objectives for this solution    for i in range(2):        m.Pa...

To work with general expressions, you may need to add intermediate decision variables, see How do I model logical and general expressions? This is not only the case for constraints but also for con...

Hi Purnima, You need to set the parameter for each objective. If you have 2 objectives, you can access the environment for both objectives and then set parameters as follows env0 = m.getMultiobjEnv...

Which Gurobi Version do you use? Could you please also add the log file?

Hi Ankan, Thanks for pointing out this issue! Our developers fixed the bug. The fix will be part of the release 10.0.2 available probably in Q2 or Q3 of this year.As a workaround for the time being...

I cannot reproduce the issue. You probably need to share the complete reproducible example.

This is still not enough information to help you. Your problem is probably not defined properly.Could you explain a bit more about what you exactly want to solve? Why do you have variables vars and...

This is not a reproducible example. If I understand you correctly you started with the Gurobi example tsp_c++.cpp. But why do you change something in the code if you want to get more feasible solut...

I think your error is in init_x() when declaring the variables. The second for-loop should be for (int k = 0; k < customers; k++) instead of for (int k = 0; k < vehicles; k++)
