I am trying to speed up the solving process of a pretty big scheduling problem.
I had the idea of using lazy constraints so that the most restrictive constraints are added later in the solving process.
My problem is that the presolve does not work as well with the lazy constraints and so the model solved with the lazy constraints is a lot bigger than the one without.
Is there any way I could still use lazy constraints with a full presolve or other ways around this problem?
