Package org.uma.evolver.algorithm.base

Class EvolutionaryAlgorithmBuilder<S extends org.uma.jmetal.solution.Solution<?>>

java.lang.Object

org.uma.evolver.algorithm.base.EvolutionaryAlgorithmBuilder<S>

Type Parameters:

S - the type of solutions handled by the algorithm

public class EvolutionaryAlgorithmBuilder<S extends org.uma.jmetal.solution.Solution<?>>
extends Object

A builder class for creating instances of EvolutionaryAlgorithm with optional archive support. This builder provides a flexible way to configure and instantiate evolutionary algorithms, with or without an external archive for storing non-dominated solutions.

Example usage:

 EvolutionaryAlgorithm<DoubleSolution> algorithm = new EvolutionaryAlgorithmBuilder<DoubleSolution>()
     .build(
         "NSGA-II",
         initialSolutionsCreation,
         evaluation,
         termination,
         selection,
         variation,
         replacement,
         archive  // can be null if no archive is needed
     );

build

public org.uma.jmetal.component.algorithm.EvolutionaryAlgorithm<S> build(String name,
 org.uma.jmetal.component.catalogue.common.solutionscreation.SolutionsCreation<S> initialSolutionsCreation,
 org.uma.jmetal.component.catalogue.common.evaluation.Evaluation<S> evaluation,
 org.uma.jmetal.component.catalogue.common.termination.Termination termination,
 org.uma.jmetal.component.catalogue.ea.selection.Selection<S> selection,
 org.uma.jmetal.component.catalogue.ea.variation.Variation<S> variation,
 org.uma.jmetal.component.catalogue.ea.replacement.Replacement<S> replacement,
 org.uma.jmetal.util.archive.Archive<S> archive)

Builds an instance of EvolutionaryAlgorithm with the specified components.

Parameters:

name - the name of the algorithm (used for identification and logging)

initialSolutionsCreation - component responsible for creating the initial population

evaluation - component that handles solution evaluation

termination - condition that determines when the algorithm should stop

selection - operator for selecting parent solutions

variation - operator for creating new solutions through recombination and mutation

replacement - strategy for updating the population with new solutions

archive - optional archive for storing non-dominated solutions (can be null)

Returns:

a configured instance of EvolutionaryAlgorithm

Throws:

IllegalArgumentException - if any required parameter is null (except archive)
