MILP: values that are constrained to be equal, have a 0.000001 difference
回答済みThis fact affects the solution time a lot, as I guess the solver tries to optimize in such a small scale the variables. any ideas?

Thank you very much for your response. I guess you mean continuous variables that are used (auxiliary) in big-M expressions ? By saying expression bounded do you mean something different than just ...

MILP solution taking too long, while the incumbent obj value is at the optimal level from early on
Using GUROBI with python. When solving a MILP, I notice that the incumbent is very early (25sec) at the optimal point but the best bound is so slow to fall (maximization problem) that it takes ages...
