Hi, Sir or Madam,
I was working on a MILP design&UC model(bi-level MILP), which is not that large, but now it took ages to obtain the optimal results(3-4 days), too long to wait, the MIPgap, best bound and incumbent all moved slowly. I have tried several methods based on a guideline online, like:
1. check model formulation, but from my knowledge, it is good.
2. parameters tuning, tried several parameters combination:
ops.gurobi.MIPGap = 0.02;
ops.gurobi.Threads = 4;
ops.gurobi.NormAdjust = 1;
ops.gurobi.Cuts = 2;
ops.gurobi.MIPFocus = 1;
ops.gurobi.Heuristics = 0.1;
ops.gurobi.Method = 3;
The log was shown as following, could you please help look at it and give some suggestions?
Thanks a lot, and looking forward to your reply.
