I have a minimization problem, that is modeled to be solved in Gurobi, via python.
Besides, I can calculate a "good" initial solution for the problem separately, that can be used as an upper bound for the problem.
What I want to do is to set Gurobi use this upper bound, to enhance its efficiency. I mean, if this upper bound can help Gurobi for its search. The point is that I just have the objective value, but not a complete solution.
Can anybody help me how to set this upper bound in the Gurobi?
Thanks.
I think that if you can calculate a good solution, you can also know some bound for your variable even you dont have the solution exactly ?
How to set an start solution in Gurobi, when only objective function is known?
