    public class WekaGeneticAlgorithm
extends AbstractArrayProvider
implements GeneticFitnessChangeListener, CallableActorUser, OptionalCallableActor, FlowPauseStateListener, Pausable
    Applies the genetic algorithm to the incoming dataset.
    Forwards the best setup(s) after the algorithm finishes.
    A callable sink can be specified for receiving intermediate performance results.

    Input/output:
    - accepts:
       weka.core.Instances
       adams.flow.container.WekaGeneticAlgorithmInitializationContainer
    - generates:
       adams.flow.container.WekaGeneticAlgorithmContainer


    Container information:
    - adams.flow.container.WekaGeneticAlgorithmInitializationContainer: Algorithm, Data
    - adams.flow.container.WekaGeneticAlgorithmContainer: Setup, Measure, Fitness, WeightsStr, Weights 

    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: WekaGeneticAlgorithm
 
    -annotation <adams.core.base.BaseAnnotation> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this
    actor encounters an error; the error gets propagated; useful for critical
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing
    actor handler must have this enabled as well.
    default: false
 
    -output-array <boolean> (property: outputArray)
    If enabled, outputs the containers as array rather than one-by-one.
    default: false
 
    -algorithm <adams.opt.genetic.AbstractClassifierBasedGeneticAlgorithm> (property: algorithm)
    The genetic algorithm to apply to the dataset.
    default: adams.opt.genetic.DarkLord -stopping-criterion adams.opt.genetic.stopping.MaxIterations -initial-setups-provider adams.opt.genetic.initialsetups.EmptyInitialSetupsProvider -generator weka.classifiers.DefaultCrossValidationFoldGenerator -classifier weka.classifiers.rules.ZeroR -setup-upload adams.opt.genetic.setupupload.Null
 
    -callable <adams.flow.core.CallableActorReference> (property: callableName)
    The name of the callable sink to forward to the adams.flow.container.WekaGeneticAlgorithmContainer 
    containers.
    default: unknown
 
    -optional <boolean> (property: optional)
    If enabled, then the callable sink is optional, ie no error is raised if 
    not found, merely ignored.
    default: false
 
    -test-data <adams.flow.control.StorageName> (property: testData)
    The storage item with the test data; cross-validation is performed if not 
    present or the algorithm doesn't support test data handling.
    default: storage
