bsearchmut2: Boundary Search Mutation 2

Description

Boundary Search Mutation-2 is an algorithm based on searching the convenience region boundaries in constraint processing for NLP optimization (Michalewicz & Schoenauer, 1996). Two genes are randomly selected from the chromosome and one is multiplied by the random value p, while the other gene is multiplied by the q value calculated using p.

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

Usage

bsearchmut2(y, ...)

Arguments

y

A vector. Chromosome of the offspring

…

Further arguments passed to or from other methods.

Value

mutant

A vector. Chromosome of the offspring

mutgen

A vector. The numbers of the mutated genes.
