A Short Survey on Watson-Crick Automata
نویسندگان
چکیده
This paper surveys some known results in Watson-Crick automata theory. In particular, we concentrate on the computational power, complexity measures, decidability problems, and systems of Watson-Crick automata working together on the same input. This selection of topics is not exhaustive, reflecting the research interests of the authors. A series of open problems and questions is also included.

Equivalence of Subclasses of Two-Way Non-Deterministic Watson Crick Automata
Watson Crick automata are finite automata working on double strands. Extensive research work has already been done on non deterministic Watson Crick automata and on deterministic Watson Crick automata. Parallel Communicating Watson Crick automata systems have been introduced by E. Czeziler et al. In this paper we discuss about a variant of Watson Crick automata known as the two-way Watson Crick...
متن کاملOn the power of parallel communicating Watson-Crick automata systems
Parallel communicating Watson-Crick automata systems were introduced in [2] as possible models of DNA computations. This combination of Watson-Crick automata and parallel communicating systems comes as a natural extension due to the new developments in DNA manipulation techniques. It is already known, see [5], that for Watson-Crick finite automata, the complementarity relation plays no active r...
متن کاملParallel Communicating Watson-Crick Automata Systems
Watson-Crick automata are finite state automata working on doublestranded tapes, introduced to investigate the potential of DNA molecules for computing. In this paper we introduce the concept of parallel communicating Watson-Crick automata systems. It consists of several Watson-Crick finite automata parsing independently the same input and exchanging information on request, by communicating sta...
متن کاملWatson-Crick automata: determinism and state complexity
Watson-Crick automata are finite state automata working on double-stranded tapes, introduced to investigate the potential of DNA molecules for computing. In this paper, we continue the investigation of descriptional complexity of Watson-Crick automata initiated in [9]. In particular, we show that any finite language as well as any unary regular language can be recognized by a Watson-Crick autom...
متن کاملSome Relationships between Classes of Reverse Watson-Crick Finite Automata
A Watson-Crick automaton is recently introduced as a computational model of DNA computing framework. It works on tapes consisting of double stranded sequences of symbols. Symbols placed on the corresponding cells of the double-stranded sequences are related by a complimentary relation. In this paper, we investigate a variation of Watson-Crick automata in which both heads read the tape in revers...
