randmut3: Random mutation 3

Description

For each gene, if a random number is less than the mutation rate, the gene's mean value is zero and its standard deviation is |ub-lb| The random value selected from the normal distribution is changed by adding it (Yoon & Kim, 2012).

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

Usage

randmut3(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.
