      public EpsilonProgressCollector()
      Constructs an unattached collector for recording the number of ε-progress improvements detected in an EpsilonBoxEvolutionaryAlgorithm.

    • EpsilonProgressCollector

      public EpsilonProgressCollector(EpsilonBoxEvolutionaryAlgorithm algorithm)
      Constructs a collector for recording the number of ε-progress improvements detected in the specified EpsilonBoxEvolutionaryAlgorithm.
      Parameters:
      algorithm - the algorithm this collector records data from

  • Method Details

    • collect

      public void collect(Observation observation)
      Description copied from interface: Collector
      Collects the requested information from the object, storing the data to the specified observation. This method must only be invoked after this collector has been attached to an appropriate object.
      Specified by:
      collect in interface Collector
      Parameters:
      observation - the observation to which the collected data is stored

    • getAttachPoint

      public AttachPoint getAttachPoint()
      Description copied from interface: Collector
      Returns the attach point describing where this collector is attached. The matched object should be unique.
      Specified by:
      getAttachPoint in interface Collector
      Returns:
      the attach point describing where this collector is attached

    • attach

      public Collector attach(Object object)
      Description copied from interface: Collector
      Returns a new instance of this collector which has been attached to the specified object as identified by the attach point returned through Collector.getAttachPoint().
      Specified by:
      attach in interface Collector
      Parameters:
      object - the matching object
      Returns:
      a new instance of this collector which has been attached to the specified object

    • getNumberOfImprovements

      public static int getNumberOfImprovements(Observation observation)
      Reads the number of improvements from the observation.
      Parameters:
      observation - the observation
      Returns:
      the number of improvements

    • getNumberOfDominatingImprovements

      public static int getNumberOfDominatingImprovements(Observation observation)
      Reads the number of dominating improvements from the observation.
      Parameters:
      observation - the observation
      Returns:
      the number of dominating improvements
