Hi Zahra. What exactly is the error that is raised when you try and add the feasibility cut?

Hi Johan, Apologies for the delay. It's an interesting idea. Do you mean like an automated tool for advanced user-scaling? If so, I have been playing around with an idea that could be useful for th...

Hi Vadim, I had a quick look and I don't believe there is a way to remove the z variables completely (I might be wrong). Given the equality constraints in    solver.addConstr(z[time_interval + 1] =...

Hi Vadim, Thanks for the clarification. Yes, it should be possible to express the model just in terms of the x and y variables. Well really, you only need the first of the x variables, x[0]. From x...

Hi Vadim, Glad to hear you resolved the issue :-). It isn't clear to me what you mean by "define z to be a dictionary and not a variable, Gurobi tells me the model is infeasible". I would encourage...

Hi Vadim, Thanks for reaching out. I tried running that code you sent through and I get a feasible solution, although slightly different from the one you mention; mine has X=3. It is not clear to m...

Hi Sean, Thanks for reaching out. That is quite peculiar. I notice that you are using 9.1.1 and also that a Compute Server Worker is involved. Can you first try upgrading to 9.1.2 and seeing whethe...

Apologies, the typesetting was confused. That line should be, print(m.Params.MIPGap)

Hi Deanna, This really is strange. Although it appears you are setting the MIPGap parameter with m.setParam('MIPGap', 0), the log file suggests that this update is not coming through. Gwyneth, was ...
