I just tested this and found that you'll have to re-add the lazy constraints, for every reoptimization. To answer your questions: Gurobi "forgets" lazy constraints right after the optimization The...

Thanks for the explanation. This matches my understanding. With my original post I wanted to gain a better understanding of the Distributed MIP algorithms in Gurobi. The parts which I don't quite u...

Hi Matthias Hmm... I think you misread my original post? In my example I ran Gurobi on a *single* node, not on a cluster. Best regards,Simon

No, unfortunately I haven't been able to do more experiments. I have only used 9.1 without DistributedMIP.

Hi Mathias Barrier=2 probably helps to give you a quicker root node solution. But this will not do anything to accelerate the search. For that you could see whether "NoRelHeurTime=3600" (or so) hel...
