Computing with Multi-row Gomory Cuts
Recent advances on the understanding of valid inequalities from the infinite group relaxation has opened the possibility of finding a computationally effective extension to GMI cu...

On optimizing over lift-and-project closures
The lift-and-project closure is the relaxation obtained by computing all lift-and-project cuts from the initial formulation of a mixed integer linear program or equivalently by co...

Improved Strategies for Branching on General Disjunctions
Abstract Within the context of solving Mixed-Integer Linear Programs by a Branch-andCut algorithm, we propose a new strategy for branching. Computational experiments show that, on ...

Runway sequencing with holding patterns
We study a scheduling problem, motivated by air-traffic control, in which a set of aircrafts are about to land on a single runway. When coming close to the landing area of the air...

Approximate extended formulations
Mixed integer programming (MIP) formulations are typically tightened through the use of a separation algorithm and the addition of violated cuts. Using extended formulations involv...
