pbx: Position-Based Crossover (PBX)

In adana: Adaptive Nature-Inspired Algorithms for Hybrid Genetic Optimization

Position-Based Crossover (PBX)

Description

The Position-Based Crossover (PBX) operator inserts a different number of randomly selected genes in one parent into the same position in Offspring1, then rounds off the other genes in sequence according to their positions in the other parent (Syswerda, 1991). Other offspring are generated similarly if desired or necessary. PBX is an operator that tries to ensure diversity in recombination while taking care to preserve position.

Usage

pbx(x1, x2, cxon, ...)

Arguments

x1	A vector. It contains the chromosomal information of parent-1.
x2	A vector. It contains the chromosomal information of parent-2.
cxon	Number of offspring to be generated as a result of crossover
...	Further arguments passed to or from other methods.

Value

A matrix containing the generated offsprings.
