Method Detail

maxSearchIndex

protected int maxSearchIndex(int ceLength)

Specified by:

maxSearchIndex in class AbstractTTTLambda<net.automatalib.automaton.fsa.DFA<?,I>,I,Boolean>

getState

protected DTLeaf<I,Boolean> getState(net.automatalib.word.Word<I> prefix)

Specified by:

getState in class AbstractTTTLambda<net.automatalib.automaton.fsa.DFA<?,I>,I,Boolean>

getHypothesisModel

public net.automatalib.automaton.fsa.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 should not be modified by external code (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<net.automatalib.automaton.fsa.DFA<?,I>,I,Boolean>

Returns:

the current hypothesis model.

dtree

protected AbstractDecisionTree<I,Boolean> dtree()

Specified by:

dtree in class AbstractTTTLambda<net.automatalib.automaton.fsa.DFA<?,I>,I,Boolean>

size

public int size()

Specified by:

size in interface net.automatalib.automaton.concept.FiniteRepresentation
