Package org.uma.evolver.algorithm.meta

Class MetaSMPSOBuilder

java.lang.Object

org.uma.evolver.algorithm.meta.MetaSMPSOBuilder

public class MetaSMPSOBuilder
extends Object

Builder for creating SMPSO (Speed-constrained Multi-objective Particle Swarm Optimization) instances configured for meta-optimization tasks. This builder provides a convenient way to configure and instantiate SMPSO with appropriate settings for meta-optimization scenarios.

Key features:

• Configurable swarm size and maximum evaluations
• Parallel evaluation support
• Sensible defaults for meta-optimization tasks

Example usage:

 MetaSMPSOBuilder builder = new MetaSMPSOBuilder(metaOptimizationProblem)
     .setSwarmSize(100)
     .setMaxEvaluations(10000)
     .setNumberOfCores(4);
 ParticleSwarmOptimizationAlgorithm smpso = builder.build();

Constructor Details

MetaSMPSOBuilder

public MetaSMPSOBuilder(MetaOptimizationProblem<?> problem)

Creates a new builder with the specified meta-optimization problem.

Parameters:

problem - the meta-optimization problem to be solved (must not be null)

Throws:

org.uma.jmetal.util.errorchecking.JMetalException - if the problem is null

Method Details

setSwarmSize

public MetaSMPSOBuilder setSwarmSize(int swarmSize)

Sets the swarm size for the SMPSO algorithm.

Parameters:

swarmSize - the number of particles in the swarm (must be positive)

Returns:

this builder instance for method chaining

Throws:

org.uma.jmetal.util.errorchecking.JMetalException - if swarmSize is not positive

setMaxEvaluations

public MetaSMPSOBuilder setMaxEvaluations(int maxEvaluations)

Sets the maximum number of evaluations for the SMPSO algorithm.

Parameters:

maxEvaluations - the maximum number of function evaluations (must be positive)

Returns:

this builder instance for method chaining

Throws:

org.uma.jmetal.util.errorchecking.JMetalException - if maxEvaluations is not positive

setNumberOfCores

public MetaSMPSOBuilder setNumberOfCores(int numberOfCores)

Sets the number of cores to use for parallel evaluation.

Parameters:

numberOfCores - the number of CPU cores to use (1 for sequential execution)

Returns:

this builder instance for method chaining

Throws:

org.uma.jmetal.util.errorchecking.JMetalException - if numberOfCores is not positive

build

public org.uma.jmetal.component.algorithm.ParticleSwarmOptimizationAlgorithm build()

Builds and configures an SMPSO instance with the specified parameters.

The returned SMPSO instance is configured with:

• Default velocity constraint handling
• Multi-threaded evaluation
• Specified termination condition
• Configured swarm size

Returns:

a fully configured SMPSO instance ready for execution

Throws:

org.uma.jmetal.util.errorchecking.JMetalException - if the problem is not a DoubleProblem or configuration is invalid

ClassCastException - if the problem cannot be cast to DoubleProblem
