Avoiding Shared Clocks in Networks of Timed Automata [PDF]
Networks of timed automata (NTA) are widely used to model distributed real-time systems. Quite often in the literature, the automata are allowed to share clocks, i.e.

Connector algebras for C/E and P/T nets' interactions [PDF]
A quite flourishing research thread in the recent literature on component-based systems is concerned with the algebraic properties of different classes of connectors.

Watson-Crick conjugates of words and languages [PDF]
In this work, we explore the concept of Watson-Crick conjugates, also known as $θ$-conjugates (where $θ$ is an antimorphic involution), of words and languages.

Distributed Graph Automata and Verification of Distributed Algorithms [PDF]
Combining ideas from distributed algorithms and alternating automata, we introduce a new class of finite graph automata that recognize precisely the languages of finite graphs definable in monadic second-order logic.

A prolog toolkit for formal languages and automata [PDF]
This paper describes the first version of PFLAT (read "P flat"), a collection of Prolog predicates that aims to provide a pedagogical implementation of concepts and algorithms taught in Formal Languages and Automata Theory (FLAT) courses. By ``pedagogical implementation'' we mean on the one hand that students should be able to easily map the ...

Minimisation of Multiplicity Tree Automata [PDF]
We consider the problem of minimising the number of states in a multiplicity tree automaton over the field of rational numbers. We give a minimisation algorithm that runs in polynomial time assuming unit-cost arithmetic.

Regular tree languages in low levels of the Wadge Hierarchy [PDF]
In this article we provide effective characterisations of regular languages of infinite trees that belong to the low levels of the Wadge hierarchy. More precisely we prove decidability for each of the finite levels of the hierarchy; for the class of the ...

Characterizations of recognizable picture series [PDF]
The theory of two-dimensional languages as a generalization of formal string languages was motivated by problems arising from image processing and pattern recognition, and also concerns models of parallel computing.

Computing the Width of Non-deterministic Automata [PDF]
We introduce a measure called width, quantifying the amount of nondeterminism in automata. Width generalises the notion of good-for-games (GFG) automata, that correspond to NFAs of width 1, and where an accepting run can be built on-the-fly on any ...

Supervisory Control of (max,+) Automata: A Behavioral Approach [PDF]
A behavioral framework for control of (max,+) automata is proposed. It is based on behaviors (formal power series) and a generalized version of the Hadamard product, which is the behavior of a generalized tensor product of the plant and controller (max,+)
