RandomGaussianSF: Random Gaussian scale factor (RGSF).

In xegaDfGene: Gene Operations for Real-Coded Genes

Random Gaussian scale factor (RGSF).

Description

The scale factor is drawn randomly from one of the two Gaussian distributions abs(rnorm(1, 0.3, 0.3)) or abs(rnorm(1, 0.7, 0.3)).

Usage

RandomGaussianSF(lF)

Arguments

lF	Local configuration.

Details

For details, see section 5 of Sharma et al. (2019), p. 932 or Li and Yin (2016), p. 555. Note that the range given in both papers is false.

Value

A scale factor.
