Lattice Based Extended Formulations for Integer Linear Equality Systems

Aardal, Karen; Wolsey, Laurence A. - 2007

We study different extended formulations for the set X = {x E Zn | Ax = Ax0} in order to tackle the feasibility problem for the set X+ = X N Zn+. Here the goal is not to find an improved polyhedral relaxation of conv(X+), but rather to reformulate in such a way that the new variables introduced...
