Hi, Steve, The problem is solved. You are right that I actually put MIPGap attribute setting after optimize... I should've thought of that as I use MIPFocus and put it in the right place. Anyway, t...

Hi, Gwyneth, I don't think I changed any MIPGap parameter, at least I don't recall. As I said, the only places I did something about the Gap are the two line of code I have sent: Gap=m.setParam('MI...

Hi, Gwyneth, The only code I have about the log is the code to change the name of log when I export the log to a txt file. I rerun the model without exporting the log file (so in this way there is ...

Or do you mean this: Gap=max(0, abs(m.ObjVal-m.ObjBound)/abs(m.ObjVal)) The one above and the one I sent in the previous email:Gap=m.setParam('MIPGap', 0), are the only two lines about gap I have i...

How to have a solution with 0 gap
回答済みHi, Is there a way to force Gurobi to generate solution with 0 gap? I got optimal solution with positive gap for a MIP model that minimize cost. I found a solution with lower objective function val...

CPU time of first time to reach optimal solution
回答済みDear community, I am wondering how to get the CPU time of first time to reach optimal solution. I use python API. Use the example below, in this case, the wall clock time of first found optimal sol...
