Allopatric Selection

Allopatric selection

A mechanism of µGP's that loosely replicates a separate evolution happening in a closed niche. See allopatric speciation on Wikipedia for more information on the original phenomenon.

In practice, when a genetic operator is applied to an individual, among all the offspring produced, only the child with the best fitness will survive. This methodology allows the existence of operators with a considerable number of children (see for example the ScanMutation family in Genetic operators) without the risk of a colonization of the population by closely related offspring of a good parent individual.
