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
