Get Gurobi to use pure cutting plane method for MIP?

    Unfortunately, the answer to both of your questions is "no". You can tell Gurobi to use pretty much all cuts it finds by setting the "CutPasses" parameter to a very large number. But still, Gurobi won't necessarily generate all cuts required to get the convex hull of the integer feasible points. It discards cuts due to numerical reasons, it separates only cuts that are "violated enough", it may not generate all Gomory cuts due to performance reasons, and so on.

    The cuts are generated in terms of the presolved model. Because Gurobi does not allow access to the presolved model, you also cannot extract the cuts that were generated.


    Best regards,
