Controlling population size and mutation strength by Meta-ES under fitness noise
Hans-Georg Beyer, Michael Hellwig · 2013
This paper investigates strategy parameter control by Meta-ES using the noisy sphere model. The fitness noise considered is normally distributed with constant noise variance. An asymptotical analysis concerning the mutation strength and the population size is presented. It allows for the prediction of the Meta-ES dynamics. An expression describing the asymptotical growth of the normalized mutation strength is calculated. Finally, the theoretical results are evaluated empirically.
