Webb26 juni 2024 · Crossover operators can be classified into three types, asexual, sexual and multi-recombination. Asexual means that an offspring is generated from one parent, Sexual means two parents produce one or two children, and then Multi-Recombination where more than two parents are used to produce one or more offspring.

Webb2 jan. 2010 · Moreover, this crossover generates holes in the input individuals. A hole is created when an attribute of an individual is between the two crossover points of the other individual. Then it rotates the element so that all holes are between the crossover points and fills them with the removed elements in order. For more details see [Goldberg1989].
