Hi Jaromił, I think I could share the model with you privately. Is there any method I can send an link to you directly? Appreciated,EK

Gurobi worsen the coefficient ranges while it handles non-convex quadratic constraints and cause numerical issue
進行中Hi, I'm having trouble to solve my model due to numerical issue, so I'm wandering any method mitigate this numerical issue. 1) My model contains some non-convex bi-linear constraints and genera...

Warm start approach gives suboptimal solution
ユーザーの入力を待っています。Hi, I use a warm-start approach to solving MIP problems because Gurobi takes too long to solve them if I don't provide an initial feasible solution.The problem is that the results of the warm-start...

Hi Maliheh, Thanks for your prompt response. According to the log, it seems like Gurobi converted general constraints into SOS constraints. 1) Does it mean that Gurobi converted the general constra...

How to handle SOS type 1 and SOS type 2 constraints?
回答済みHello, Some constraints of my model involve general constraints: A = min[B, x] & B = piecewise linear function of x So, Gurobi converts these constraints into SOS type 1 and type 2 constraints d...

The IIS of infeasible model is feasible when I run it separately
回答済みHello, I have a question about infeasible models. Currently, Gurobi claims my model is infeasible. So after m.feasRelaxS(0, False, False, True), m.optimize() presents that the best objective is 0. ...

Hi Jue, I was able to resolve the issue by adjusting the FuncMaxVal parameter.Although I'm having another issue, I will make a separate post for it. Once again, I genuinely appreciate your help. B...

Hi Jue, I know feasible solutions satisfy all constraints. From the model, I've found a feasible solution presented below. As this solution satisfies all constraints and bounds, this solution shou...

Hi Jue, Thanks for your comments. As you mentioned, Gurobi claims that the model is infeasible, and we can find a feasible solution by violating the constraint; gLogTerm_S_mul_I[2,0,1,0] = gLogTer...

Hi Jue, Thanks for sharing your thoughts. Although I was not able to access your Jupyter Notebook, I've fixed the model and the code as follows: Model: I've adjusted parameters for general constrai...
