  author={Ilya Loshchilov and Marc Schoenauer and Mich{\`e}le Sebag and Nikolaus Hansen},
The Covariance Matrix Adaptation Evolution Strategy (CMAES) is widely accepted as a robust derivative-free continuous optimization algorithm for non-linear and non-convex optimization problems. CMA-ES is well known to be almost parameterless, meaning that only one hyper-parameter, the population size, is proposed to be tuned by the user. In this paper, we propose a principled approach called selfCMA-ES to achieve the online adaptation of CMA-ES hyper-parameters in order to improve its overall… CONTINUE READING
