Hierarchies and Characterizations of Stateless Multicounter Machines
Abstract. We investigate the computing power of stateless multicounter machines with reversal-bounded counters. Such a machine can be deterministic, nondeterministic, realtime (the...

On Stateless Multicounter Machines
We investigate the computing power of stateless multicounter machines with reversal-bounded counters. Such a machine has m-counters operating on a one-way input delimited by left a...

On Stateless Automata and P Systems
We introduce the notion of stateless multihead two-way (respectively, oneway) NFAs and stateless multicounter systems and relate them to P systems and vector addition systems. In ...

On Stateless Multihead Finite Automata and Multihead Pushdown Automata
A stateless k-head two-way deterministic finite automaton (k-head 2DFA), has only one state, hence the designation stateless. Its transitions depends solely on the symbols currentl...

Dense Counter Machines and Verification Problems
We generalize the traditional definition of a multicounter machine (where the counters, which can only assume nonnegative integer values, can be incremented/decremented by 1 and te...
