Lifted Tableaux Inequalities for 0--1 Mixed-Integer Programs: A Computational Study

We describe families of inequalities for 0--1 mixed-integer programming problems that are obtained by lifting cover and packing inequalities. We show that these inequalities can be separated from single rows of the simplex tableaux of their linear programming relaxations. We present the results of a computational study comparing their performance with that of Gomory mixed-integer cuts on a collection of MIPLIB and randomly generated 0--1 mixed-integer programs. The computational study shows that these cuts yield better results than Gomory mixed-integer cuts.
