Defined in:

Overview

This class manages fixed gene counts in evolvable instances. Unlike the CountGene, the RigidCountGene maintains a constant number of genes that doesn't change during evolution. This is used when a gene is defined with a fixed integer for count: (e.g., count: 5).

Examples:

Define a chord with exactly 4 notes

class Chord
  include Evolvable

  gene :notes, type: NoteGene, count: 4

  # The number of notes will always be 4, never changing during evolution
  def play
    puts "Playing chord with #{notes.count} notes"
  end
end

Class Method Details

.combine(gene_a, _gene_b) ⇒ RigidCountGene

Combines two rigid count genes by always returning the first one. This ensures the count remains constant during evolution.

Parameters:
