MULTI-STACK-COUNTER LANGUAGES,
Abstract
A stack-counter acceptor is a stack acceptor in which the storage alphabet is just one letter. The present paper discusses multi-stack-counter acceptors operating in quasi-realtime, i.e., acceptors in which each storage tape is a stack counter and in which there are only a bounded number of consecutive E-moves. It is shown that the quasi-real-time k-stack-counter acceptor is equivalent to one operating in nondeterministic real-time. Lastly, it is shown that acceptance by final state of a k-stack-counter acceptor is equivalent to acceptance by empty tape and final state. (Author)
