Abstract:

In the context of functions optimization, self-adaptation features of evolutionary search algorithms have been explored only with evolution strategies (ES) and evolutionary programming (EP). In this paper, we demonstrate the self-adaptive feature of real-parameter genetic algorithms (GAs) using the simulated binary crossover (SBX) operator. The connection between the working of self-adaptive ESs and real-parameter GAs with SBX operator is also discussed. The self-adaptive behavior of real parameter GAs is demonstrated on a number of test problems commonly-used in the ES literature. The remarkable similarity in the working of real-parameter GAs and self-adaptive ESs shown in the study suggests the need of emphasizing further studies on self-adaptive GAs.
