SelectUniformP: Selection with uniform probability without replacement.

In xegaSelectGene: Selection of Genes and Gene Representation Independent Functions

Selection with uniform probability without replacement.

Description

SelectUniformP() implements selection by choosing a gene with equal probability without replacement. Usage:

1. To specify mating behavior in crossover operators.

2. For computer experiments without selection pressure.

Usage

SelectUniformP(fit, lF, size = 1)

Arguments

fit	Fitness vector.
lF	Local configuration.
size	Number of selected genes. Default: 1.

Details

Selection without replacement guarantees that vectors of different indices are selected. A vector of the size of the population is a permutation of indices. This property is needed for the classic variant of differential evolution.

Value

The index vector of the selected genes.
