this wiki is not completed…and now a bit out of date
This GA was written with the intention of making a flexible framework which could easily be extended to include many variations on the theme of algorithmic evolution. This is my first object oriented GA, and being OO this has enabled functionality to be parcelled in a manor consistent with natural systems. Instead of the usual notion of a population being just an Array of genomes and these being either a String or an Array, the population here is an object which provides population centric functions that act on a group of Individuals. Individuals, also objects contain Genome objects and each type of object is responsible for actions relevant to its type. E.g. Genomes perform the actions of recombination and mutation, whilst Populations perform the actions of selection Individuals etc. Evolution is also an object in its own right, one which is passed a population and arguments and coordinates the actions of evolution.
- class Population => A collection of Individuals
- class Individual => The Container for Genomes
- module Fitness => returns value for an individuals fitness
- Genome => Genetic Material
- module GeneInitializer => defines how a new genome should be created
- module Recombination => defines how genomes are combined to form new genomes
- module Mutator => defines how genomes will mutate
- class Evolution => Takes population a coordinates evolution for that population
This is still a work in progress. At some point I want to package it up into a gem for ease of use.
I would like to have feed back on this, let me know if you spot any typos, conceptos or dyslexisums, or just genneral suggestions.
