Adapting the Covariance Matrix in Evolution Strategies

Silja Meyer-Nieberg, Erik Kropat

Abstract

Evolution strategies belong to the best performing modern natural computing methods for continuous optimization. This paper addresses the covariance matrix adaptation which is central to the algorithm. Nearly all approaches so far consider the sample covariance as one of the main factors for the adaptation. However, as known from modern statistics, this estimate may be of poor quality in many cases. Unfortunately, these cases are encountered often in practical applications. This paper explores the use of different previously unexplored estimates.
