    Mixed-Integer Cuts from Cyclic Groups
    Download  www.dei.unipd.it
    We analyze a separation procedure for Mixed-Integer Programs related to the work of Gomory and Johnson on interpolated subadditive functions. This approach has its roots in the Go...

    Can Pure Cutting Plane Algorithms Work?
    Download  www2.isye.gatech.edu
    We discuss an implementation of the lexicographic version of Gomory's fractional cutting plane method and of two heuristics mimicking the latter. In computational testing on a...

    On optimizing over lift-and-project closures
    Download  www.optimization-online.org
    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...

    On Using Cutting Planes in Pseudo-Boolean Optimization
    Download  sat.inesc.pt
    Cutting planes are a well-known, widely used, and very effective technique for Integer Linear Programming (ILP). However, cutting plane techniques are seldom used in PseudoBoolean...
