SelectLRSelective: Linear rank selection with selective pressure.

In xegaSelectGene: Selection of Genes and Gene Representation Independent Functions

Linear rank selection with selective pressure.

Description

SelectLRSelective() implements selection by Whitley's linear rank selection with selective pressure for the GENITOR algorithm. See Whitley, Darrell (1989), p. 121.

Usage

SelectLRSelective(fit, lF, size = 1)

Arguments

fit	Fitness vector.
lF	Local configuration.
size	Size of return vector (default: 1).

Details

The selection pressure is configured by the constant function lF$SelectionBias(). Its values should be strictly larger than 1 and preferably below 2. The default is set to 1.5. A value of 1.0 means uniform random selection.

Value

The index vector of selected genes.
