Hi. Thanks for your prompt reply. By time per incumbent, referring back to the image above, incumbent 1264.00000 took 87s before going to incumbent 1177.000000. My question was whether I could limi...

Hi. Is there a way to set a time limit per Incumbent (as per image)? Or can you only set a time limit using Params.TimeLimit? ThanksOleg

Hi. Thanks for your reply. If going with the MIP start approach, you first have to produce a MIP start (.mst) or a solution (.sol) file. My questions are: Can a model be optimised more than once? ...

Hi. Thanks for your help! Worked like a charm. Wish I knew this beforehand.

Hi. Thank you for the suggestion. But I am still getting that the model is infeasible. Here is my updated code with another constraint: # Constraints 4.13max_valCA1SH = grb_model.addVar(lb=-GRB.IN...

Hi after doing what you suggested, it is still giving me the same issue when looking at the ilp file

Hi again. Upon inspection, I noticed that the model is being infeasible because of the following constraints: grb_model.addConstr((ca1sh.min - quicksum(x[i,j,s] for s in ca1sh.slots for j in team_...

When doing what you suggested, it is giving me the following error: Any ideas?

So it would be along the lines of this: i_CA1SH = [] for ca1sh in CA1SH: for i in ca1sh.teams: i_CA1SH.append((i,ca1sh)) di_CA1SH = grb_model.addVars(i_CA1SH) for ca1sh in CA1SH: fo...
