Abstract

Abstract

En 中文
In this article, we propose a Lagrangian smoothing algorithm for quadratic assignment problems, where the continuation subproblems are solved by the truncated Frank-Wolfe algorithm. We establish practical stopping criteria and show the algorithm finitely terminates at a KKT point of a continuation subproblem. The quality of the returned solution is studied in detail. Finally, limited numerical results are provided. (C) 2009 Elsevier Ltd. All rights reserved.
