How to ensure consistent values of .PI when the dual problem has multiple optimal solutions?
OngoingHello, 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...

Why do the dual cost obtained by .pi seem incorrect, when the upper and lower bounds of variables are defined using "model.addVar"?
AnsweredHello, 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...
