gaussmut {adana}

Gauss Mutation

Description

Gauss Mutation is an operator made by adding randomly selected values from a normal distribution with a mean of 0 and a standard deviation of sigma to a randomly selected gene in the chromosome (Michalewicz, 1995; Back et.al., 1991; Fogel, 1995).

This operator is used for value encoded (integer or real number) chromosomes.

Usage

gaussmut(y, mutsdy, ...)

Arguments

y

A vector. Chromosome of the offspring

mutsdy

A vector. Vector of standard deviations of genes

...

Further arguments passed to or from other methods.

Value

mutant

A vector. Chromosome of the offspring

mutgen

The number of the mutated gene.
