Class FitnessEvaluationWorker


  • public class FitnessEvaluationWorker
    extends Object
    This is the class that actually runs the fitness evaluation tasks created by a EvolutionEngine. This responsibility is abstracted away from the evolution engine to permit the possibility of creating multiple instances across several machines, all fed by a single shared work queue, using Terracotta (http://www.terracotta.org) or similar.
    • Method Detail

      • submit

        public <T> Future<EvaluatedCandidate<T>> submit​(org.uncommons.watchmaker.framework.FitnessEvalutationTask<T> task)
      • main

        public static void main​(String[] args)
        Entry-point for running this class standalone, as an additional node for fitness evaluations. If this method is invoked without using Terracotta (or similar) to share the work queue, the program will do nothing.
        Parameters:
        args - Program arguments, should be empty.
      • finalize

        protected void finalize()
                         throws Throwable
        A FitnessWorker cannot be garbage-collected if its thread pool has not been shutdown. This method, invoked on garabage collection (or maybe not at all), shuts down the thread pool so that the threads can be released.
        Overrides:
        finalize in class Object
        Throws:
        Throwable - Any exception or error that occurs during finalisation.
