Edge Recombination Crossover (ERX)

Description

The Edge Recombination Crossover (ERX) operator ignores outbound directions, that is, it evaluates a chromosome with an undirected edge loop (Whitley et.al., 1989). This operator is based on the concept of neighborhood, as the main idea is to prioritize the edges common to both parents when creating offspring.

Usage

erx(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.
