Synchronization of finite automata

MV Volkov - 2022 - elar.urfu.ru
A survey of the state-of-the-art of the theory of synchronizing automata is given in its part
concerned with the case of complete deterministic automata. Algorithmic and complexity …

Reduced checking sequences using unreliable reset

GV Jourdan, H Ural, H Yenigün - Information Processing Letters, 2015 - Elsevier
The length of a checking sequence (CS) generated from a deterministic, minimal, and
completely specified finite state machine model M of a system under test which does not …

Forward and backward synchronizing algorithms

A Roman, M Szykuła - Expert Systems with Applications, 2015 - Elsevier
Abstract Automata synchronization has many important applications, mostly in conformance
testing of electrical circuits, self-correcting codes and protocol testing. Finding a shortest …

A machine learning approach to synchronization of automata

I Podolak, A Roman, M Szykuła, B Zieliński - Expert Systems with …, 2018 - Elsevier
We present a novel method to predict the length of the shortest synchronizing words of a
finite automaton by applying the machine learning approach. We introduce several so-called …

Flushgeist: Cache leaks from beyond the flush

P Vila, A Abel, M Guarnieri, B Köpf… - arXiv preprint arXiv …, 2020 - arxiv.org
Flushing the cache, using instructions like clflush and wbinvd, is commonly proposed as a
countermeasure against access-based cache attacks. In this report, we show that several …

Synchronizing automata with extremal properties

A Kisielewicz, M Szykuła - … Foundations of Computer Science 2015: 40th …, 2015 - Springer
We present a few classes of synchronizing automata exhibiting certain extremal properties
with regard to synchronization. The first is a series of automata with subsets whose shortest …

[PDF][PDF] Attainable values of reset thresholds

M Dzyga, R Ferens, VV Gusev… - … Foundations of Computer …, 2017 - drops.dagstuhl.de
An automaton is synchronizing if there exists a word that sends all states of the automaton to
a single state. The reset threshold is the length of the shortest such word. We study the set …

Preimage problems for deterministic finite automata

MV Berlinkov, R Ferens, M Szykuła - Journal of Computer and System …, 2021 - Elsevier
Given a subset of states S of a deterministic finite automaton and a word w, the preimage is
the subset of all states mapped to a state in S by the action of w. We study three natural …

Complexity of preimage problems for deterministic finite automata

MV Berlinkov, R Ferens, M Szykula - … International Symposium on …, 2018 - drops.dagstuhl.de
Given a subset of states S of a deterministic finite automaton and a word w, the preimage is
the subset of all states that are mapped to a state from S by the action of w. We study the …

ˇCerny-Starke conjecture from the sixties of XX century

AN Trahtman - arXiv preprint arXiv:2003.06177, 2020 - arxiv.org
A word $ s $ of letters on edges of underlying graph $\Gamma $ of deterministic finite
automaton (DFA) is called synchronizing if $ s $ sends all states of the automaton to a …
