org.uma.evolver.parameter.factory.MOPSOParameterFactory

All Implemented Interfaces:

ParameterFactory<org.uma.jmetal.solution.doublesolution.DoubleSolution>

public class MOPSOParameterFactory
extends Object
implements ParameterFactory<org.uma.jmetal.solution.doublesolution.DoubleSolution>

Factory class for creating and configuring categorical parameters specific to the MOPSO algorithm. This factory implements the ParameterFactory interface to provide type-safe creation of various MOPSO-specific components and their parameters.

The factory supports the creation of parameters for different MOPSO components including:

• Archive management (leader and external archives)
• Swarm initialization and velocity computation
• Mutation and perturbation strategies
• Inertia weight computation
• Velocity and position update mechanisms
• Local and global best management

This implementation is specifically designed for the MOPSO algorithm working with double-encoded solutions and provides appropriate parameter types that are compatible with the DoubleSolution interface.

Method Details

createParameter

public CategoricalParameter createParameter(String parameterName,
 List<String> values)

Creates and returns a specific CategoricalParameter instance based on the provided parameter name. This factory method centralizes the creation of all parameter types used in the MOPSO algorithm.

The following parameter types are supported:

Specified by:

createParameter in interface ParameterFactory<org.uma.jmetal.solution.doublesolution.DoubleSolution>

Parameters:

parameterName - the name of the parameter to create (case-sensitive)

values - the list of possible string values for the parameter (must not be null or empty)

Returns:

an instance of CategoricalParameter corresponding to the specified parameter name

Throws:

IllegalArgumentException - if the values list is null or empty
