Public Instance methods

crossover(crossover_rate)

Perform the crossover step in a population, giving a new population

make_next_generation(tournament_winner_success_rate = 0.8, game_length = 1000, crossover_rate = 0.7, mutation_rate = 0.05)

mutation(mutation_rate)

Perform the mutation step in a population, giving a new population

tournament_select_one(winner_success_chance = 0.8, max_game_length= 1000, verbose = false)

Use tournament selection to pick an individual for the next generation

tournament_select_population(winner_success_chance = 0.8, max_game_length = 1000, verbose = false)

Select a new population the same size as the current population
