Order-based crossover (OX2)

Description

Order-based crossover (OX2) is a crossover operator for permutation encoded chromosomes. It is an operator that forces the order of several randomly selected positions in one parent to the other parent (Syswerda, 1991).

Usage

ox2(x1, x2, cxon, cxoxk, ...)

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
cxoxk	Number of genes to be changed
...	Further arguments passed to or from other methods.

Value

A matrix containing the generated offsprings.
