This module implements a Genetic Algorithm (GA) in pure Perl. Other Perl
|
|
modules that achieve the same thing (perhaps better, perhaps worse) do
|
|
exist. Please check CPAN. I mainly wrote this module to satisfy my own
|
|
needs, and to learn something about GAs along the way.
|
|
|
|
I will not go into the details of GAs here, but here are the bare basics.
|
|
Plenty of information can be found on the web.
|
|
|
|
In a GA, a population of individuals compete for survival. Each individual
|
|
is designated by a set of genes that define its behaviour. Individuals
|
|
that perform better (as defined by the fitness function) have a higher
|
|
chance of mating with other individuals. When two individuals mate, they
|
|
swap some of their genes, resulting in an individual that has properties
|
|
from both of its "parents". Every now and then, a mutation occurs where
|
|
some gene randomly changes value, resulting in a different individual. If
|
|
all is well defined, after a few generations, the population should
|
|
converge on a "good-enough" solution to the problem being tackled.
