چکیده

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) complementarity characteristic for DNA computing. The new Watson-Crick D0L systems are still deterministic and generate their language as a sequence. However, the capability of modeling growth is greatly enhanced: the new growth functions are not necessarily even Z -rational. TUCS Research Group Mathematical Structures of Computer Science

The phenomenon known as Watson-Crick complementarity is basic both in the experiments and theory of DNA computing. While the massive parallelism of DNA strands makes exhaustive searches possible, complementarity constitutes a powerful computational tool. It is also very fruitful to view complementarity as a language-theoretic operation: \bad" words obtained through a generative process are repl...

Universal computation with Watson-Crick D0L systems

Watson-Crick D0L systems, introduced in 1997 by V. Mihalache and A. Salomaa, arise from two major principles: the Lindenmayer rewriting and the Watson-Crick complementarity principle. Complementarity can be viewed as a purely language-theoretic operation. Majority of a certain type of symbols in a string (purines vs. pyrimidines) triggers a transition to the complementary string. The paper deal...

Iterated Morphisms with Complementarity on the DNA Alphabet

Watson-Crick complementarity can be viewed as a language-theoretic operation: \bad" words obtained through a generative process are replaced by their complementary ones. This idea seems particularly suitable for Lindenmayer systems. D0L systems augmented with a speci c complementarity transition, Watson-Crick D0L systems, have turned out to be a most interesting model and have already been exte...
