#find_count_gene(key) ⇒ <Type>

Parameters:

  • key (<Type>)

Returns:

  • (<Type>)

def find_count_gene(key)
  @config.dig(key, :count_gene)
end

#find_gene(key) ⇒ <Type>

Returns the first gene with the given key. In the Melody example above, the instrument gene has the key :instrument so we might write something like: instrument_gene = melody.find_gene(instrument)

Parameters:

  • key (<Type>)

Returns:

  • (<Type>)

# File 'lib/evolvable/genome.rb', line 28

def find_gene(key)
  @config.dig(key, :genes, 0)
end

#find_genes(*keys) ⇒ <Type>

Returns an array of genes that have the given key. Gene keys are defined in the EvolvableClass.search_space method. In the Melody example above, the key for the note genes would be :notes. The following would return an array of them: note_genes = melody.find_genes(:notes)

Parameters:

  • *keys (<Type>)

Returns:

  • (<Type>)

  @config.values_at(*keys).flat_map { _1&.fetch(:genes, []) || [] }
end

#find_genes_count(key) ⇒ <Type>

Parameters:

  • key (<Type>)

Returns:
