      static StoppingCriteria.Factory getCombined​(StoppingCriteria.Factory[] subCriteria)
      A stopping criteria that is a composite of a set of criteria, stops when at least one sub criteria wants to stop
      static StoppingCriteria.Factory getIterationCount​(int maxIterationCount)
      A stopping criteria that stops after a set number of iterations
      static StoppingCriteria.Factory getNonExactUnchangedScore​(int maxIterationCountAtCurrentScore, boolean matchBestScore, double tolerance)
      A stopping criteria that works by counting how many iterations occur at a given score (either the best score or the current score) and stopping when score does not change after a set number of generations

      • getIterationCount

        public static final StoppingCriteria.Factory getIterationCount​(int maxIterationCount)
        A stopping criteria that stops after a set number of iterations
        Parameters:
        maxIterationCount - the maximum number of iterations.

      • getUnchangedScore

        public static final StoppingCriteria.Factory getUnchangedScore​(int maxIterationCountAtCurrentScore,
                                                               boolean matchBestScore)
        A stopping criteria that works by counting how many iterations occur at a given score (either the best score or the current score) and stopping when score does not change after a set number of generations
        Parameters:
        maxIterationCountAtCurrentScore - the number of iterations to wait at the current score before stopping
        matchBestScore - if true will examine the best score so far, else will examine the current score so far.

        A stopping criteria that works by counting how many iterations occur at a given score (either the best score or the current score) and stopping when score does not change after a set number of generations
        Parameters:
        maxIterationCountAtCurrentScore - the number of iterations to wait at the current score before stopping
        matchBestScore - if true will examine the best score so far, else will examine the current score so far.

      • getCombined

        public static final StoppingCriteria.Factory getCombined​(StoppingCriteria.Factory[] subCriteria)
        A stopping criteria that is a composite of a set of criteria, stops when at least one sub criteria wants to stop
        Parameters:
        subCriteria - an array of StoppingCriteria to combine
