Abstract

Estimation of Distribution Algorithms are a class of evolutionary algorithms characterized by the use of probabilistic models. These algorithms have been applied successfully to a wide set of artificial and real-world problems, achieving competitive results in most scenarios. Nevertheless, there are some problems whose solutions can be naturally represented as a permutation, for which EDAs have not been extensively developed. Although some work has been done in this area, most of the approaches are adaptations of EDAs designed for problems based on integer or real domains, and only a few algorithms have been specifically designed to deal with permutation-based problems. In this paper, we present an EDA that learns probability distributions over permutations. Particularly, our approach is based on the use of k-order marginals. In addition, we carry out some preliminary experiments over classical permutation-based problems in order to study the performance of the proposed k-order marginals EDA.
