Using constraint techniques for a safe and fast implementation of optimality-based reduction

Published: 11 March 2007 Publication History

Abstract

Optimality-based reduction attempts to take advantage of the known bounds of the objective function to reduce the domain of the variables, and thus to speed up the search of a global optimum. However, the basic algorithm is unsafe, and thus, the overall process may no longer be complete and may not reach the actual global optimum. Recently, Kearfott has proposed a safe implementation of optimality-based reduction. Unfortunately, his method suffers from some limitations and is rather slow. In this paper, we show how constraint programming filtering techniques can be used to implement optimality-based reduction in a safe and efficient way.
