powmut2: Power Mutation 2

Description

Power Mutation is an operator that generates a mutation in a random gene at a certain power of a random number. In this operator, a different exponent parameter can be given for each gene.

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

Usage

powmut2(y, lb, ub, mutpow, ...)

Arguments

y

A vector. Chromosome of the offspring

lb

A vector. Lower bounds of genes

ub

A vector. Upper bounds of genes

mutpow

A vector of exponent parameter

…

Further arguments passed to or from other methods.

Value

mutant

A vector. Chromosome of the offspring

mutgen

The number of the mutated gene.
