Fenchel Cutting Planes for Integer Programs

Operations Research, 1994
A technique for generating cutting planes for integer programs is introduced that is based on the ability to optimize a linear function on a polyhedron rather than explicit knowledge of the underlying polyhedral structure of the integer program. The theoretical properties of the cuts and their relationship to Lagrangian relaxation are discussed, the ...

T-space and cutting planes

Mathematical Programming, 2003
The T-space [\textit{R. E. Gomory}, Some polyhedra related to combinatorial problems. Combinat. Struct. Appl., Proc. Calgary internat. Conf. combinat. Struct. Appl., Calgary 1969), 117 (1970; Zbl 0245.90019)] associated to an integer programming problem IP is the ambient space of integer coefficients of group elements of the group relaxation of IP.

Cutting Planes from Wide Split Disjunctions

2017
In this paper, we discuss an extension of split cuts that is based on widening the underlying disjunctions. That the formula for deriving intersection cuts based on splits can be adapted to this case has been known for a decade now. For the first time though, we present applications and computational results.

Cancelling cuts in the regge plane

Physics Letters, 1963
The application of the unitary condition in crossed channels suggests the possibility of cuts in the Regge plane. An example from perturbation theory is given in which cancellations between separate terms in the unitary sum removes unwelcome singularities. (C.E.S.)

Cutting-Plane Theory: Disjunctive Methods

1977
This paper is a survey, with new results, of the disjunctive methods of cutting-plane theory, which were devised by Balas, Glover, Owen, Young, and other researchers, over the past half decade. The basic disjunctive cut principle is derived, its interrelations with the other cut-producing procedures are discussed, and applications of it are given. Many
