The 16th International Conference on Automata and Formal Languages (AFL 2023) was held in Eger, September 5-7, 2023. It was organized by the Eszterházy Károly Catholic University o…
On the number of useful objects in P systems with active membranes
Zsolt Gazdag, Károly Hajagos, Szabolcs Iván
In this paper we investigate the number of objects actually used in the terminating computations of a certain variant of polarizationless P systems with active membranes. The P sys…
Scattered one-counter languges have rank less than
Szabolcs Ivan
A linear ordering is called context-free if it is the lexicographic ordering of some context-free language and is called scattered if it has no dense subordering. Each scattered or…
On the Order Type of Scattered Context-Free Orderings
Kitti Gelle, Szabolcs Iván
We show that if a context-free grammar generates a language whose lexicographic ordering is well-ordered of type less than , then its order type is effectively computable.
The order type of scattered context-free orderings of rank one is computable
Kitti Gelle, Szabolcs Ivan
A linear ordering is called context-free if it is the lexicographic ordering of some context-free language and is called scattered if it has no dense subordering. Each scattered or…
The ordinal generated by an ordinal grammar is computable
Kitti Gelle, Szabolcs Ivan
A prefix grammar is a context-free grammar whose nonterminals generate prefix-free languages. A prefix grammar is an ordinal grammar if the language is well-ordered with…
