Evolutionary Algorithm¶

class jmetal.algorithm.singleobjective.evolutionaryalgorithm.ElitistEvolutionStrategy(problem: jmetal.core.problem.Problem[S], mu: int, lambd_a: int, max_evaluations: int, mutation: jmetal.core.operator.Mutation[S])¶

Bases: jmetal.core.algorithm.EvolutionaryAlgorithm

create_initial_population() → typing.List[S]¶

evaluate_population(population: typing.List[S]) → typing.List[S]¶

get_name() → str¶

get_result() → R¶

init_progress()¶

is_stopping_condition_reached() → bool¶

replacement(population: typing.List[S], offspring_population: typing.List[S]) → typing.List[S]¶

reproduction(population: typing.List[S]) → typing.List[S]¶

selection(population: typing.List[S]) → typing.List[S]¶

update_progress()¶

class jmetal.algorithm.singleobjective.evolutionaryalgorithm.GenerationalGeneticAlgorithm(problem: jmetal.core.problem.Problem[S], population_size: int, max_evaluations: int, mutation: jmetal.core.operator.Mutation[S], crossover: jmetal.core.operator.Crossover[S, S], selection: jmetal.core.operator.Selection[typing.List[S], S], evaluator: jmetal.component.evaluator.Evaluator[S])¶
