Thanks to your recommendation, I upgraded my Gurobi from version 10 to 11.0.0. However, I have issues with the updated version, and it is not functioning as expected, even for problems that worked ...

fix_num = 4 * 1000  # numeratorfix_den = 3.6 * 3.14 * ro * V_max  # denominatorfor edge in df_edges.index:     model.addConstr(fix_den * D_edge_2[edge] * D_edge_2[edge] == fix_num * mass_edge[edge])

Thank you very much for your assistance; I have implemented all of your suggestions. However, I have a challenge in finding the Incumbent of the objective function. I believe this issue may be a...

Thank you. I have a question about the method that Gurobi employs to find the best objective function. In many of my optimization models, the Best Bound of Objective Bounds is not feasible, especia...

Yes, i guess it too. Thanks a lot. 

Yes, but it is very weird because when i want to limit some variables it takes more time. in this special problem when i set this heuristics solver parameter model.setParam(GRB.Param.Heuristics, 0....

I tried it but it doesn't work (it's same as before). i have a constraint such as:  model.addConstr(aux1[edge] == fix * mass_edge[edge] * Bp[edge])model.addConstr(D_edge[edge] * D_edge[edge] >= (au...

 I think it is better I use the root 2 in objective function for that. Can i implement it by  Model.addGenConstrPow()? 

Thanks.https://app.box.com/s/0n6wu03jh4xmof86rltg1vlsm4u4ut86
