Package org.uma.evolver.algorithm.base

Class ParticleSwarmOptimizationBuilder

java.lang.Object

org.uma.evolver.algorithm.base.ParticleSwarmOptimizationBuilder

public class ParticleSwarmOptimizationBuilder
extends Object

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

Example usage:

 Algorithm<List<DoubleSolution>> algorithm = new ParticleSwarmOptimizationBuilder()
     .build(
         "MOPSO",
         initialSwarmCreation,
         evaluation,
         termination,
         velocityInitialization,
         localBestInitialization,
         globalBestInitialization,
         inertiaWeightStrategy,
         velocityUpdate,
         positionUpdate,
         perturbation,
         globalBestUpdate,
         localBestUpdate,
         globalBestSelection,
         globalBestArchive,
         externalArchive  // can be null if no external archive is needed
     );

Builds an instance of ParticleSwarmOptimizationAlgorithm with the specified components.

Parameters:

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

solutionsCreation - component responsible for creating the initial swarm

evaluation - component that handles solution evaluation

termination - condition that determines when the algorithm should stop

velocityInitialization - strategy for initializing particle velocities

localBestInitialization - strategy for initializing local best solutions

globalBestInitialization - strategy for initializing global best solutions

inertiaWeightStrategy - strategy for computing inertia weight during the search

velocityUpdate - operator for updating particle velocities

positionUpdate - operator for updating particle positions

perturbation - operator for applying perturbations to solutions

globalBestUpdate - strategy for updating the global best solution

localBestUpdate - strategy for updating local best solutions

globalBestSelection - strategy for selecting the global best solution

globalBestArchive - archive for storing global best solutions

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

Returns:

a configured instance of ParticleSwarmOptimizationAlgorithm

Throws:

NullPointerException - if any required parameter is null (except externalArchive)
