On the landscape ruggedness of the quadratic assignment problem

Published: 28 July 2001 Publication History

Abstract

Local-search-based heuristics have been demonstrated to give very good results to approximately solve the quadratic assignment problem (QAP). In this paper, following the works of Weinberger and Stadler, we introduce a parameter, called the ruggedness coeffcient, which measures the ruggedness of the QAP landscape which is the union of a cost function and a neighborhood. We give an exact expression, and a sharp lower bound for this parameter. We are able toderive from it that the landscape of the QAP is rather flat, and so it gives a theoretical justification of the effectiveness of local-search-based heuristics for this problem. Experimental results with simulated annealing are presented which con8rm this conclusion and also the influence of the ruggedness coe5cient on the quality of results obtained.
