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 …

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 …

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 …

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 …

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 …

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 …

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 …

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 …
