Convergence Properties of Evolution Strategies with the Derandomized Covariance Matrix Adaptation: T

The intermediate (center of mass) recombination of object parameters is introduced in the evolution strategy with derandomized covariance matrix adaptation (CMA-ES). On various (unimodal) real space tness functions convergence properties and robustness against distorted selection are tested for diierent parent numbers. Introducing (== I ;)-selection signiicantly improves robustness and has comparatively minor innuence on the convergence speed of the CMA-ES.
