Local Optima Networks, Landscape Autocorrelation and Heuristic Search Performance

Free registration required

Executive Summary

Recent developments in fitness landscape analysis include the study of Local Optima Networks (LON) and applications of the Elementary Landscapes theory. This paper represents a first step at combining these two tools to explore their ability to forecast the performance of search algorithms. The authors base their analysis on the Quadratic Assignment Problem (QAP) and conduct a large statistical study over 600 generated instances of different types. Their results reveal interesting links between the network measures, the autocorrelation measures and the performance of heuristic search algorithms.
