Integer programming is a crucial branch of mathematical optimisation that focuses on problems where some or all decision variables are constrained to be integers. This field underpins many practical ...

The Journal of the Operational Research Society, Vol. 52, No. 5 (May, 2001), pp. 567-575 (9 pages) Several preprocessing rules to reduce integer programming problem size are proposed and examined for ...

Abstract: Let P be a set of 3k points in the Euclidean plane. A 3-matching is a partition of P into k subsets of 3 points each, called triplets. The cost of each triplet {a, b, c} is given by min{|ab| ...

Abstract: This paper is about the primal-dual relationship in a mixed integer programming problem (MIP) in which integer variables are binary. It shows how the primal-dual relationship of a linear ...

Formulations of mathematical programs often require that some of the decision variables take only integer values. Consider the formulation You can follow the same steps to identify binary variables.
