Reformulation and decomposition of integer programs [PDF]

In this survey we examine ways to reformulate integer and mixed integer programs. Typically, but not exclusively, one reformulates so as to obtain stronger linear programming relaxations, and hence better bounds for use in a branch-and-bound based ...

Isometric Cylinder Method for Strict Mixed-integer Linear Programming

, 2009
In this paper, we solve strict mixed-integer linear programming not including integer linear programming by isometric cylinder method under the MATLAB environment. The algorithm considers the optimization problems for both whole and real variables of the

A note on the split rank of intersection cuts [PDF]

In this note, we present a simple geometric argument to determine a lower bound on the split rank of intersection cuts. As a first step of this argument, a polyhedral subset of the lattice-free convex set that is used to generate the intersection cut is ...

Convex approximations for a class of mixed-integer recourse models [PDF]

We consider mixed-integer recourse (MIR) models with a single recourse constraint.We relate the secondstage value function of such problems to the expected simple integer recourse (SIR) shortage function.
