History−Register Automata [PDF]

open access: yes, 2013
Programs with dynamic allocation are able to create and use an unbounded number of fresh resources, such as references, objects, files, etc. We propose History-Register Automata (HRA), a new automata-theoretic formalism for modelling such programs. HRAs

Multi-Head Finite Automata: Characterizations, Concepts and Open Problems [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2009
Multi-head finite automata were introduced in (Rabin, 1964) and (Rosenberg, 1966). Since that time, a vast literature on computational and descriptional complexity issues on multi-head finite automata documenting the importance of these devices has been ...

A Formal Model for Semantic Computing Based on Generalized Probabilistic Automata

open access: yesEntropy, 2019
In most previous research, “semantic computing” refers to computational implementations of semantic reasoning. It lacks support from the formal theory of computation.

Robust Controller Synthesis in Timed Automata [PDF]

open access: yes, 2013
We consider the fundamental problem of Büchi acceptance in timed automata in a robust setting. The problem is formalised in terms of controller synthesis: timed automata are equipped with a parametrised game-based semantics that models the possible ...

Efficient Multistriding of Large Non-deterministic Finite State Automata for Deep Packet Inspection [PDF]

open access: yes, 2012
Multistride automata speed up input matching because each multistriding transformation halves the size of the input string, leading to a potential 2x speedup.

An Easy to Check Characterization of Positive Expansivity for Additive Cellular Automata Over a Finite Abelian Group

open access: yesIEEE Access, 2023
Additive cellular automata over a finite abelian group are a wide class of cellular automata (CA) that are able to exhibit most of the complex behaviors of general CA and they are often exploited for designing applications in different practical contexts.

Generalized Results on Monoids as Memory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
We show that some results from the theory of group automata and monoid automata still hold for more general classes of monoids and models. Extending previous work for finite automata over commutative groups, we demonstrate a context-free language that ...

On the Existence of Universal Finite or Pushdown Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We investigate the (non)-existence of universal automata for some classes of automata, such as finite automata and pushdown automata, and in particular the influence of the representation and encoding function.

Efficient Equivalence Checking Technique for Some Classes of Finite-State Machines

open access: yesМоделирование и анализ информационных систем, 2020
Finite transducers, two-tape automata, and biautomata are related computational models descended from the concept of Finite-State Automaton. In these models an automaton controls two heads that read or write symbols on the tapes in the one-way mode.
