Given a reduced deterministic finite state machine, there always exists a homing sequence of length polynomial with respect to the number of states of the machine. For nondeterministic reduced finite state machines, a homing sequence may not exist, and moreover, if it exists, its length can be exponential. We show that the problem of deriving a homing sequence cannot be reduced to deriving a synchronizing word for underlying automata and should be studied independently. We also propose a novel class of (n−1)-input finite state machines with n states whose shortest homing sequence is of length 2n−1−1.
