Abstract: | Representation techniques are important issues when designing successful evolutionary algorithms. Within this field the use
of neutrality plays an important role. We examine the use of bit-wise neutrality introduced by Poli and López (2007) from a theoretical point of view and show that this mechanism only enhances mutation-based evolutionary algorithms if not
the same number of genotypic bits for each phenotypic bit is used. Using different numbers of genotypic bits for the bits
in the phenome we point out by rigorous runtime analyses that it may reduce the optimization time significantly. |
