Implements an equivalence check by complete exploration up to a given depth, i.e.,
by testing all possible sequences of a certain length within a specified range.
Implements an equivalence test by applying the W-method test on the given
hypothesis automaton, as described in "Testing software design modeled by finite state machines"
by T.S.
Implements an equivalence test by applying the Wp-method test on the given hypothesis automaton,
as described in "Test Selection Based on Finite State Models" by S.
