On the Exact Separation of Mixed Integer Knapsack Cuts
During the last decades, much research has been conducted deriving classes of valid inequalities for single-row mixed integer programming polyhedrons. However, no such class has ha...

Two-Step MIR Inequalities for Mixed Integer Programs
Two-step MIR inequalities are valid inequalities derived from a facet of a simple mixedinteger set with three variables and one constraint. In this paper we investigate how to eff...

An Augment-and-Branch-and-Cut Framework for Mixed 0-1 Programming
In recent years the branch-and-cut method, a synthesis of the classical branch-and-bound and cutting plane methods, has proven to be a highly successful approach to solving large-s...

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...

Lifting, superadditivity, mixed integer rounding and single node flow sets revisited
In this survey we attempt to give a unified presentation of a variety of results on the lifting of valid inequalities, as well as a standard procedure combining mixed integer roun...
