I have a question about presolve and cutting planes in gurobi. In the gurobi documentation, the following is stated:
" The idea of cutting planes is that they tighten the formulation by removing undesirable fractional solutions, as in the case of MIP presolve, but that they do this during the solution process and without the undesirable side-effect of creating additional sub-problems (unlike branching). "
From this I understand that cuts in gurobi are generated during the branch and bound (the solution process) and not (solely) in the presolve section.
However, in one of the requests on the forum, the following is stated in an answer:
"Gurobi generates these cuts in the presolved model space. " (https://support.gurobi.com/hc/en-us/community/posts/360057921811-Extract-cutting-planes)
I am therefore a bit lost: where exactly are cutting planes generated? Only in the presolve section, or also dynamically during the branch and bound procedure?
