Abstract

Metaheuristic (and other) methods are often implemented using standardized parameter values. This is most often seen when comparing a favorite method with competing methods, but also when inexperienced researchers implement a method for the first time. Often the (hidden) correlations between the search method components and parameters are neglected or ignored, using only standardized templates. This paper looks at some of these pitfalls or hidden correlations, using the mechanisms of tabu search (TS) as examples. The points discussed are illustrated by examples from the authors experience.
