A New Selection Ratio for Large Population Sizes

Part of the Lecture Notes in Computer Science book series (LNCS, volume 6024)


Motivated by parallel optimization, we study the Self-Adaptation algorithm for large population sizes. We first show that the current version of this algorithm does not reach the theoretical bounds, then we propose a very simple modification, in the selection part of the evolution process. We show that this simple modification leads to big improvement of the speed-up when the population size is large.
