Module: Evolvable::Gene::ClassMethods

Defined in:

lib/evolvable/gene.rb

Overview

Class methods added to classes that include Evolvable::Gene. These methods enable gene-level behaviors like combination during evolution.

Instance Method Summary

• #combine(gene_a, gene_b) ⇒ Evolvable::Gene

  Combines two genes to produce a new gene during the combination phase.

• #key ⇒ Symbol

  Returns the unique key for this gene type.

• #key=(val) ⇒ Object

  Sets the unique key for this gene type.

Instance Method Details

#combine(gene_a, gene_b) ⇒ Evolvable::Gene

Combines two genes to produce a new gene during the combination phase. By default, randomly picks one of the two parent genes.

Override this method in your gene class to implement custom combination behavior.

Parameters:

• gene_a (Evolvable::Gene) —

  The first gene to combine

• gene_b (Evolvable::Gene) —

  The second gene to combine

Returns:

• (Evolvable::Gene) —

  A new gene resulting from the combination

# File 'lib/evolvable/gene.rb', line 141

def combine(gene_a, gene_b)
  [gene_a, gene_b].sample
end

#key ⇒ Symbol

Returns the unique key for this gene type.

Returns:

• (Symbol) —

  The key that identifies this gene type

# File 'lib/evolvable/gene.rb', line 127

def key
  @key
end

#key=(val) ⇒ Object

Sets the unique key for this gene type. The key is typically set automatically when using the gene macro.

Parameters:

• val (Symbol) —

  The key to identify this gene type

# File 'lib/evolvable/gene.rb', line 118

def key=(val)
  @key = val
end
