Instance Method Details

#call(population) ⇒ Evolvable::Population

Performs the combination operation on the population. Creates new evolvables by combining parent genomes.

Parameters:

def call(population)
  new_evolvables(population, population.size)
  population
end

#combine_genomes(genome_1, genome_2) ⇒ Evolvable::Genome

Combines two parent genomes to create a new genome. For each gene key, combines the count genes and individual genes.

def combine_genomes(genome_1, genome_2)
  new_config = {}
  genome_1.each do |gene_key, gene_config_1|
    gene_config_2 = genome_2.config[gene_key]
    count_gene = combine_count_genes(gene_config_1, gene_config_2)
    genes = combine_genes(count_gene.count, gene_config_1, gene_config_2)
    new_config[gene_key] = { count_gene: count_gene, genes: genes }
  end
  Genome.new(config: new_config)
end

#new_evolvables(population, count) ⇒ Array<Evolvable>

Creates new evolvable instances by combining parent genomes. For each new evolvable, selects parent genomes and combines them.

Parameters:

  • population (Evolvable::Population) —

    The population containing parent evolvables

  • count (Integer) —

    The number of new evolvables to create

Returns:

  • (Array<Evolvable>) —

    The newly created evolvables
