This paper investigates the accepting powers of one-way alternating and deterministic multi-counter automata operating in realtime. We partially solve the open problem posed in , and show that for each k1, there is a language accepted by a realtime one-way deterministic (k+3)-counter automaton, but not accepted by any realtime one-way alternating k-counter automaton.
