[HTML][HTML] On the computational completeness of graph-controlled insertion–deletion systems with binary sizes

H Fernau, L Kuppusamy, I Raman - Theoretical Computer Science, 2017 - Elsevier
A graph-controlled insertion–deletion (GCID) system is a regulated extension of an insertion–
deletion system. Such a system has several components and each component has some …

Universal matrix insertion grammars with small size

H Fernau, L Kuppusamy, S Verlan - … 2017, Fayetteville, AR, USA, June 5-9 …, 2017 - Springer
We study matrix insertion grammars (MIS) towards representation of recursively enumerable
languages with small size. We show that pure MIS of size (3; 1, 2, 2)(ie, having ternary …

Investigations on the power of matrix insertion-deletion systems with small sizes

H Fernau, L Kuppusamy, I Raman - Natural Computing, 2018 - Springer
Matrix insertion-deletion systems combine the idea of matrix control (a control mechanism
well established in regulated rewriting) with that of insertion and deletion (as opposed to …

Single semi-contextual insertion-deletion systems

S Ivanov, S Verlan - Natural Computing, 2021 - Springer
In this paper we consider the model of single insertion-deletion systems that at each step
insert or delete a single symbol in a context-free manner (ie at any position in the word). The …

Parikh images of matrix ins-del systems

H Fernau, L Kuppusamy - Theory and Applications of Models of …, 2017 - Springer
Matrix insertion-deletion systems combine the idea of matrix control (as established in
regulated rewriting) with that of insertion and deletion (as opposed to replacements). We …

On homomorphic images of the Szilard languages of matrix insertion–deletion systems with matrices of size 2

P Paul, G Zhang, D Guo, M Zhu - Journal of Membrane Computing, 2022 - Springer
A Szilard language is a well-known tool in formal language theory to express the derivation
process in a grammar system or grammar. Matrix InsDel (insertion–deletion) system is a well …

[PDF][PDF] BONDED SEQUENTIAL AND PARALLEL INSERTION-DELETION SYSTEMS IN FORMAL LANGUAGE THEORY

AF YOSMAN - 2022 - eprints.utm.my
Insertion and deletion are set operations that act upon structures in a predetermined fashion
to create language generating devices in formal language theory, a field that involves the …

On describing super-linear languages by matrix insertion–deletion systems

I Raman, L Kuppusamy - International Journal of Advances in Engineering …, 2019 - Springer
Matrix insertion–deletion (matrix ins–del) systems combine the idea of matrix control (as
established in regulated rewriting) with that of insertion and deletion operations (as opposed …
