Watson-Crick D0L Systems
D0L systems constitute the simplest and most widely studied type of Lindenmayer systems. They have the remarkable property of generating their language as a (word) sequence and, consequently, are very suitable for modeling growth properties. In this paper a new type of D0L systems is introduced, where the parallelism presented in L systems is combined with the paradigm of (Watson-Crick) complem...
متن کاملRestricted deterministic Watson-Crick automata
In this paper, we introduce a new model of deterministic Watson-Crick automaton namely restricted deterministic WatsonCrick automaton which is a deterministic Watson-Crick automaton where the complementarity string in the lower strand is restricted to a language L. We examine the computational power of the restricted model with respect to L being in different language classes such as regular, u...
متن کاملMulti-head Watson-Crick automata
Inspired by multi-head finite automata and Watson-Crick automata in this paper, we introduce a new structure namely multi-head Watson-Crick automata where we replace the single tape of multi-head finite automaton by a DNA double strand. The content of the second tape is determined using a complementarity relation similar to Watson-Crick complementarity relation. We establish the superiority of ...
متن کاملWatson-Crick Quantum Finite Automata
one-way quantum finite automata are reversible in nature, which greatly reduces its accepting property. In fact, the set of languages accepted by one-way quantum finite automata is a proper subset of regular languages. In this paper, we replace the tape head of one-way quantum finite automata with DNA double strand and name the model Watson-Crick quantum finite automata. The noninjective comple...
متن کاملModularized Context-Free Grammars
Given two context-free grammars (CFGs), G 1 and G 2 , the language generated by the union of the grammars is not the union of the languages generated by each grammar: L(G 1 G 2) 6 = L(G 1) L(G 2). In order to account for mod-ularity of grammars, another way of deening the meaning of grammars is needed. This paper adapts results from the semantics of logic programming languages to CFGs. We discu...
