Method Detail

maxSearchIndex

protected int maxSearchIndex(int ceLength)

Specified by:

maxSearchIndex in class AbstractOptimalTTT<DFA<?,I>,I,Boolean>

getState

protected DTLeaf<I,Boolean> getState(Word<I> prefix)

Specified by:

getState in class AbstractOptimalTTT<DFA<?,I>,I,Boolean>

getHypothesisModel

public DFA<?,I> getHypothesisModel()

Description copied from interface: LearningAlgorithm

Returns the current hypothesis model.

N.B.: By the contract of this interface, the model returned by this method may not be modified (i.e., M generally should refer to an immutable interface), and its validity is retained only until the next invocation of LearningAlgorithm.refineHypothesis(DefaultQuery). If older hypotheses have to be maintained, a copy of the returned model must be made.

Please note that it should be illegal to invoke this method before an initial invocation of LearningAlgorithm.startLearning().

Specified by:

getHypothesisModel in interface LearningAlgorithm<DFA<?,I>,I,Boolean>

Returns:

the current hypothesis model.

dtree

Specified by:

Specified by:

isCanonical in class AbstractOptimalTTT<DFA<?,I>,I,Boolean>

hypOutput

protected Boolean hypOutput(Word<I> word,
                            int length)
