An In-Out Approach to Disjunctive Optimization
Cutting plane methods are widely used for solving convex optimization problems and are of fundamental importance, e.g., to provide tight bounds for Mixed-Integer Programs (MIPs). T...

Repairing MIP infeasibility through local branching
Finding a feasible solution to a generic Mixed-Integer Program (MIP) is often a very difficult task. Recently, two heuristic approaches called Feasibility Pump and Local Branching...

Lot-sizing with production and delivery time windows
We study two different lot-sizing problems with time windows that have been proposed recently. For the case of production time windows, in which each client specific order must be ...
