Abstract

This paper proposes a novel modification to the covariance matrix adaptation evolution strategy (CMA-ES) introduced by (Hansen and Ostermeier, 1996) under a special problem setting. In this paper the case is considered when the function which has to be optimized takes a matrix as input. Here an approach is presented where without vectorizing directly matrices are sampled and column and row-wise covariance matrices are adapted in each iteration of the proposed evolution strategy to adapt the mutation distribution. The method seems to be able to capture correlations in the entries of the considered matrix and adapt the corresponding covariance matrices accordingly. Numerical tests are performed on the proposed method to show advantages and disadvantages.
