Hi Riley,Thanks for the reply. I’ve created a small, self-contained example that reproduces the issue. Since the code is part of an unpublished research project, I’d prefer to share it privately. C...

addCut ignored despite PreCrush=1 in Branch-and-Cut implementation
回答済みHello,I'm implementing a Branch-and-Cut algorithm for my problem using Gurobi, and I'm trying to add problem-specific user cuts through the callback. I have set the following parameters: PreCrush =...

A likely explanation could be that multiple heuristics applied to the same LP relaxation solution found solutions that violate the same lazy constraint. Does this mean that disabling the Gurobi h...

Thank you Maliheh for your quick answer. I understand your point. Due to multi-threading and the time it takes for newly added lazy constraints to sync among all threads, you might encounter solut...

Redundant Cuts using Lazy
回答済みHello, I'm working on a branch-and-cut algorithm. Through my analysis of the algorithm's efficiency, I noticed that many of the lazy constraints are redundant. Specifically, even after cutting a so...
