Apply LazyConstraintGenerator if and only if an improved integral solution is found for cbc

Perhaps related to this, but I have a situation (using CBC with mip-python) where it seems like the solver is ignoring my lazy constraints. For example, at some point in...

Apply LazyConstraintGenerator if and only if an improved integral solution is found for cbc

@sebheger It will be difficult to produce a minimal example since the particular cut being violated is part of a larger MILP, but I will see if I can come...
