Graph-controlled insertion-deletion systems
In this article, we consider the operations of insertion and deletion working in a graph-
controlled manner. We show that like in the case of context-free productions, the …

[PDF][PDF] On minimal context-free insertion-deletion systems
S Verlan - J. Autom. Lang. Comb., 2007 - researchgate.net
We investigate the class of context-free insertion-deletion systems. It is known that such
systems are universal if the length of the inserted/deleted string is at least three. We show …

Insertion-deletion systems with one-sided contexts
It was shown in (Verlan, 2005) that complexity measures for insertion-deletion systems need
a revision and new complexity measures taking into account the sizes of both left and right …

Computational power of insertion–deletion (P) systems with rules of size two
This article investigates insertion–deletion systems of small size, where at most two symbols
can be used in the description of insertion or deletion rules in a context-free or contextual …

Matrix insertion–deletion systems
We investigate in this article the operations of insertion and deletion working in a matrix-
controlled manner. We show that this allows to us strictly increase the computational power …

[PDF][PDF] DNA computing: Models and implementations
As the fabrication of integrated circuits continues to take place on increasingly smaller
scales, we grow closer to several fundamental limitations on electronic computers. For many …

P systems with minimal insertion and deletion
In this paper, we consider insertion–deletion P systems with priority of deletion over
insertion. We show that such systems with one-symbol context-free insertion and deletion …

Further results on insertion-deletion systems with one-sided contexts
In this article we continue the investigation of insertion-deletion systems having a context
only on one side of insertion or deletion rules. We show a counterpart of the results obtained …

On the weight of universal insertion grammars
We study the computational power of pure insertion grammars. We show that pure insertion
grammars of weight 3 can characterize all recursively enumerable languages. This is …
