randmut2 {adana}R Documentation

Random mutation 2

Description

For each gene, if a random number is less than the mutation rate, the gene's value is modified by adding a random value selected from the normal distribution with a mean of zero and a standard deviation of 0.1x(ub-lb).

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

Usage

randmut2(y, lb, ub, mutpm, ...)

Arguments

y

A vector. Chromosome of the offspring

lb

A vector. Lower bounds of genes

ub

A vector. Upper bounds of genes

mutpm

Mutation rate

...

Further arguments passed to or from other methods.

Value

mutant

A vector. Chromosome of the offspring

mutgen

The number of the mutated gene.
