Thank you, Maliheh. I'm glad to receive your message. Yes, I am running Gurobi via Python. The model has been written the model into an MPS file and run by reading it from the MPS file. But the pro...

How to ensure consistent values of .PI when the dual problem has multiple optimal solutions?
進行中Hello, I'm encountering an issue while using .PI to obtain the values of dual variables. I ran the same code multiple times without making any changes, yet the results of .PI turned out to be diffe...

Thank you, sir. The problem is, I have to keep the bounds in variable definitions, and I want to find a way that I don't have to use m.RC for adjustments. Any solutions?

Hello sir, I hope you don't mind me adding some more details to the question I asked earlier. I followed your advice and used .RC to get the reduced cost for each variable. I noticed that the VBas...

Thank you, Riley. I have a further question. When there are degenerate bounds, is there a way to reflect the values of m.RC into m.Pi so that I don't have to use m.RC for adjustments and can just u...

Why do the dual cost obtained by .pi seem incorrect, when the upper and lower bounds of variables are defined using "model.addVar"?
回答済みHello, I have defined a model called RMP with the following form: The upper and lower bounds of the variables (lb=0 and ub=1) are defined using "model.addVar" rather than constraints. After optimi...
