On Stateless Automata and P Systems

چکیده
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 particular, we investigate the decidability of the emptiness and reachability problems for these stateless automata and show that the results are applicable to similar questions concerning certain variants of P systems, namely, token systems and sequential tissue-like P systems.

On Globally Deterministic CD-Systems of Stateless R-Automata with Window Size One
It is known that cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 accept a class of semi-linear languages that properly includes all rational trace languages. Although the component automata of such a CD-system are all deterministic, the CD-system itself is not, as in each of its computations, the initial component and the successor ...
متن کاملCD-systems of stateless deterministic R(1)-automata governed by an external pushdown store
We study cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 that are governed by an external pushdown store. In this way we obtain an automata-theoretical characterization for the class of context-free trace languages.
متن کاملOn 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 currently scanned by its k heads, and in every such transition each head can move one cell left, right, or remain stationary. An input, which is delimited by end markers, is accepted if the machine, when started with all head...
متن کاملOn CD-systems of stateless deterministic R-automata with window size one
Here we study cooperating distributed systems (CD-systems) of restarting automata that are very restricted: they are deterministic, they cannot rewrite, but only delete symbols, they restart immediately after performing a delete operation, they are stateless, and they have a read/write window of size 1 only, that is, these are stateless deterministic R(1)-automata. We study the expressive power...
متن کاملHierarchy Results on Stateless Multicounter 5′ → 3′ Watson-Crick Automata
We consider stateless counter machines which mix the features of one-head counter machines and a special type of two-head Watson-Crick automata (WK-automata). Our biologically motivated machines have heads that read the input starting from the two extremes. The reading process is finished when there are no more symbols between the heads. Depending on whether the heads are required to advance at...
