I need some advice, any hints will be appreciated.
I have a MILP and I am using Gurobi to solve it. I have a feasible integer solution. When I use
mipstart, after 30 min of execution the gap is extremely high (100%). It advances a little.
However, when I do not provide the known integer feasible solution, after 30 min an integer solution is found.
So, should I use the feasible solution? If not, are there any parameters in Gurobi that I can adjust and make the lower bound better?
