Great to read that the callbacks may work. Thanks for posting the .NET references!

Hi Christoph, Maybe you could use a MESSAGE callback to retrieve the log lines programmatically and then log this into a buffer from your code.  If you are using Gurobi Instant Cloud, you could als...

Hi Kewei, It looks like you are calling Model.optimize() after computing the IIS, is this correct? This results in Status code 3 (infeasible) because the IIS is by definition an infeasible set of c...

Yes, p and m are independent objects, so modifying one will not affect the other. Best, Elisabeth

Hi Liu, If you optimize p, this will not affect the original model object m.  Concerning the modification of variable bounds on p, this also does not affect the original model object m. However, pl...

Hi Assia, Even if the optimal value is 19.0279979 and Gurobi finds it at 692s, it doesn't stop there because it has to prove that this is indeed the optimal value. Quoting What is the MIP Gap? Some...

Hi Assia, I agree with Riley, my original comment  As explained in Does using more threads make Gurobi faster? using more threads does not always speed up solve times. In your log we can see that ...

Hi Assia, As explained in Does using more threads make Gurobi faster? using more threads does not always speed up solve times. In your log we can see that the Gurobi spends all the time in the root...

Hi Gianmarco, The NoRelHeurTime parameter defines a time limit during which the No Relaxation heuristic works. This heuristic runs before the actual branch-and-bound: first the heuristic runs durin...

Hi Gianmarco,  The "infeasible" in the third column of the log means that the corresponding node was pruned by infeasibility (the constraints imposed by the branching path of that node together wit...
