java.lang.Object

pl.edu.agh.age.compute.stream.emas.reproduction.SexualReproductionPipeline<S>

Type Parameters:

S - type of the solution.

public final class SexualReproductionPipeline<S extends Solution<?>>
extends java.lang.Object

Method Detail

on

public static <S extends Solution<?>> SexualReproductionPipeline<S> on(EmasAgent firstParent,
                                                                       EmasAgent secondParent)

Create a pipeline for two given parents.

Type Parameters:

S - type of the solution

Parameters:

firstParent -

secondParent -

recombine

public SexualReproductionPipeline<S> recombine(Recombination<S> recombination)

mutate

public SexualReproductionPipeline<S> mutate(Mutation<S> mutation)

transferEnergy

public SexualReproductionPipeline<S> transferEnergy(EnergyTransfer energyTransfer)

extract

public io.vavr.Tuple2<io.vavr.collection.Seq<EmasAgent>,EmasAgent> extract()

Extracts agents from this pipeline.

Returns:

a tuple of agents: two new parents and a child.

Throws:

java.lang.IllegalStateException - if the child was not generated (usually transferEnergy was not called).
