Deterministic Set Automata [chapter]

Martin Kutrib, Andreas Malcher, Matthias Wendlandt
2014 Lecture Notes in Computer Science  
We consider the model of deterministic set automata which are basically deterministic finite automata equipped with a set as an additional storage medium.  ...  In this paper, we consider deterministic set automata (DSA) that extend deterministic finite automata by adding the storage medium of a set which, in contrast to bag automata, allows words to be stored  ...  Introduction In this section, we study the computational power of deterministic set automata. Hence, we compare the model with the known models of pushdown automata and queue automata.  ...

Minimization of Deterministic Fuzzy Tree Automata

S. Moghari, M. M. Zahedi
2014 Journal of Fuzzy Set Valued Analysis  
Until now, some methods for minimizing deterministic fuzzy finite tree automata (DFFTA) and weighted tree automata have been established by researchers.  ...  The second step is refinement of MDG and making minimization equivalency set (MES).  ...  Current studies on minimizing DFFTA 0 and deterministic weighted tree automata 0, focus on the second relation for similarity measure between the language of original automaton and its minimal version.  ...

We define a special class of hybrid automata, called Deterministic and Transversal Linear Hybrid Automata (DTLHA), whose continuous dynamics in each location are linear time-invariant (LTI) with a constant  ...  set, called a bounded epsilon-reach set, through sampling and polyhedral over-approximation of sampled states.  ...  CONCLUSION We have defined a special class of hybrid automata, called Deterministic and Transversal Linear Hybrid Automata (DTLHA), for which we can address the problem of bounded -reach set computation  ...

This paper compares various methods for constructing minimal, deterministic, acyclic, finite-state automata (recognizers) from sets of words.  ...  Motivation During last 12 years, one could see emergence of construction methods specialized for minimal, acyclic, deterministic, finite-state automata.  ...  Experiments Data sets for evaluation were taken from the domain of Natural language Processing (NLP). Acyclic automata are widely used as dictionaries.  ...

Restricted deterministic Watson-Crick automata [article]

Kingshuk Chatterjee, Kumar Sankar Ray
2016 arXiv   pre-print
We also show that computational power of restricted deterministic Watson- Crick automata with L in regular languages is same as that of deterministic Watson-Crick automata and that the set of all languages  ...  accepted by restricted deterministic Watson-Crick automata with L in unary regular languages is a proper subset of context free languages.  ...  Thus the set of all languages accepted by restricted deterministic Watson-Crick automata where L is regular contains the set of all languages accepted by deterministic Watson-Crick automata.  ...

Seminator 2 Can Complement Generalized Büchi Automata via Improved Semi-determinization [chapter]

František Blahoudek, Alexandre Duret-Lutz, Jan Strejček
2020 Lecture Notes in Computer Science  
In connection with the state-of-the-art LTL to TGBAs translator Spot, Seminator 2 produces smaller (on average) semi-deterministic automata than the direct LTL to semi-deterministic automata translator  ...  We present the second generation of the tool Seminator that transforms transition-based generalized Büchi automata (TGBAs) into equivalent semi-deterministic automata.  ...  Fig. 4 . 4 Comparison of the sizes of the semi-deterministic automata produced by Seminator 2 and Owl for the not semideterministic random set.  ...

The Hanoi Omega-Automata Format [chapter]

Tomáš Babiak, František Blahoudek, Alexandre Duret-Lutz, Joachim Klein, Jan Křetínský, David Müller, David Parker, Jan Strejček
2015 Lecture Notes in Computer Science  
The format allows acceptance conditions that are either state-based or transition-based, and also supports alternating automata.  ...  We propose a flexible exchange format for ω-automata, as typically used in formal verification, and implement support for it in a range of established tools.  ...  LTL into state-and transition-based variants of deterministic Rabin automata and generalized deterministic Rabin automata.  ...

The first result is a machineindependent characterization of languages of deterministic timed automata.  ...  We use a variant of Fraenkel-Mostowski sets (known also as nominal sets) as a framework suitable for stating and proving the following two results on timed automata.  ...  We prove that, unlike for deterministic timed automata, deterministic timed register automata are closed under minimization.  ...
