Module: Evolvable::Gene

Included in:
CountGene, RigidCountGene
Defined in:
lib/evolvable/gene.rb

Overview

For evolution to be effective, an evolvable's genes must be able to influence its behavior. Evolvables are composed of genes that can be used to run simple functions or orchestrate complex interactions. The level of abstraction is up to you.

Defining gene classes requires encapsulating some "sample space" and returning a sample outcome when a gene attribute is accessed. For evolution to proceed in a non-random way, the same sample outcome should be returned every time a particular gene is accessed with a particular set of parameters. Memoization is a useful technique for doing just this. The memo_wise gem may be useful for more complex memoizations.

Examples:

# This gene generates a random hexidecimal color code for use by evolvables.

require 'securerandom'

class ColorGene
  include Evolvable::Gene

  def hex_code
    @hex_code ||= SecureRandom.hex(3)
  end
end
