| SelectUniformP {xegaSelectGene} | R Documentation |
Selection with uniform probability without replacement.
Description
SelectUniformP implements selection
by choosing a gene with equal probability without
replacement.
Usage:
-
To specify mating behavior in crossover operators.
-
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.
