Method Detail

• 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.

• getNonExactUnchangedScore

  public static final 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

  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
