multiple scenario model running time
AnsweredI am using GUROBI multiplescenario model to solve a MIP with small perturbations from a base model. I know the solution to the base model. So I use var.VarHintVal or var.Start (not both) to guide ...

MIP with infinite number of feasible solutions
AnsweredI have a MIP where two continuous variables x and y are equivalent. So in the solution the sum (denoted by s) of x and y is determined/fixed, but there are infinite many choices of feasible solutio...
