Method Detail

refineHypothesisInternal

protected void refineHypothesisInternal(DefaultQuery<I,D> ceQuery)

Overrides:

refineHypothesisInternal in class AbstractAutomatonLStar<A,I,D,S,T,SP,TP,AI extends MutableDeterministic<S,I,T,SP,TP> & SupportsGrowingAlphabet<I>>

initialPrefixes

protected final List<Word<I>> initialPrefixes()

Overrides:

initialPrefixes in class AbstractLStar<A,I,D>

initialSuffixes

protected final List<Word<I>> initialSuffixes()

Description copied from class: AbstractLStar

Returns the list of initial suffixes which are used to initialize the table.

Specified by:

initialSuffixes in class AbstractLStar<A,I,D>

Returns:

the list of initial suffixes.

selectClosingRows

protected List<Row<I>> selectClosingRows(List<List<Row<I>>> unclosed)

Description copied from class: AbstractLStar

This method selects a set of rows to use for closing the table. It receives as input a list of row lists, such that each (inner) list contains long prefix rows with (currently) identical contents, which have no matching short prefix row. The outer list is the list of all those equivalence classes.

Overrides:

selectClosingRows in class AbstractLStar<A,I,D>

Parameters:

unclosed - a list of equivalence classes of unclosed rows.

Returns:

a list containing a representative row from each class to move to the short prefix part.
