Abstract
The cumulative step-size adaptation (CSA) based on path length control is regarded as a robust alternative to the standard mutative self-adaptation technique in evolution strategies (ES), guaranteeing an almost optimal control of the mutation operator. In this short paper it is shown that the underlying basic assumption in CSA -- the perpendicularity of expected consecutive steps -- does not necessarily guarantee optimal progress performance for (=I ; ) intermediate recombinative ES.
