On basic properties of jumping finite automata

V Vorel - International Journal of Foundations of Computer …, 2018 - World Scientific
We complete the initial study of jumping finite automata, which was started in a former article
of Meduna and Zemek [7]. The open questions about basic closure properties are solved …

Matrix insertion–deletion systems

I Petre, S Verlan - Theoretical Computer Science, 2012 - Elsevier
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 …

Random context and semi-conditional insertion-deletion systems

S Ivanov, S Verlan - Fundamenta Informaticae, 2015 - content.iospress.com
In this article we introduce the operations of insertion and deletion working in random
context and semi-conditional modes. We show that conditional application of insertion and …

Two results on discontinuous input processing

V Vorel - Descriptional Complexity of Formal Systems: 18th IFIP …, 2016 - Springer
First, we show that universality and other properties of general jumping finite automata are
undecidable, which answers questions asked by Meduna and Zemek in 2012 [12]. Second …

About one-sided one-symbol insertion-deletion P systems

S Ivanov, S Verlan - International Conference on Membrane Computing, 2013 - Springer
In this article we consider insertion-deletion P systems inserting or deleting one symbol in
one or two symbol (s) left context (more precisely of size (1, 2, 0; 1, 1, 0) and (1, 1, 0; 1, 2, 0)) …

Adding matrix control: insertion-deletion systems with substitutions III

M Vu, H Fernau - Algorithms, 2021 - mdpi.com
Insertion-deletion systems have been introduced as a formalism to model operations that
find their counterparts in ideas of bio-computing, more specifically, when using DNA or RNA …

Insertion-deletion systems with substitutions I

M Vu, H Fernau - Beyond the Horizon of Computability: 16th Conference …, 2020 - Springer
With good biological motivation, we add substitutions as a further type of operations to (in
particular, context-free) insertion-deletion systems. This way, we obtain new …

Insertion-deletion with substitutions II

M Vu, H Fernau - Descriptional Complexity of Formal Systems: 22nd …, 2020 - Springer
We discuss substitutions as a further type of operations, added to (in particular, one-sided)
insertion-deletion systems. This way, we obtain new characterizations of classes of context …

Random context and semi-conditional insertion-deletion systems

S Ivanov, S Verlan - arXiv preprint arXiv:1112.5947, 2011 - arxiv.org
In this article we introduce the operations of insertion and deletion working in a random-
context and semi-conditional manner. We show that the conditional use of rules strictly …

Synchronization, Road Coloring, and Jumps in Finite Automata

V Vorel - 2015 - dspace.cuni.cz
Multiple original results in the theory of automata and formal languages are presented,
dealing mainly with combinatorial problems and complexity questions related to reset words …
