Fast Implementations of Automata Computationssequence in a parallel way, using bit operations readily available in processors..In this paper, we generalize the technique, and characterize a class of automata for which there exists equivalent parallel, or vector, algorithms. As an application, we extend Myers result to arbitrary weighted edit d

Regularly Extended Two-Way Nondeterministic Tree Automataed nondeterministic tree automata with unranked alphabets. We obtain this result by establishing regularly extended versions of a congruence on trees and of a congruence on, so called, views. Our motivation for the study of these tree models is the Extensible Markup Language (XML), a metalanguage fo

Implicit Structures to Implement NFA’s from Regular Expressions-structure and the .-structure, an optimization of the .-structure. These representations are linear w.r.t. the sizes of the expression, since their construction is in . space and time, as well as the computation of the set δ(.) of the targets of the transitions by a of any subset . of states. The c

New Finite Automaton Constructions Based on Canonical Derivativesposition of a symbol in an expression, introduced by Glushkov and McNaugthon-Yamada, leads to an efficient computation of the position automaton (there exist quadratic space and time implementations w.r.t. the size of the expression), whereas the notion of derivative of an expression w.r.t. a word,

Experiments with Automata Compressionrature. However, their impact on the size of automata has not been described yet. We fill that gap, presenting results of experiments carried out on automata representing German, and Dutch morphological dictionaries.

A Basis for Looping Extensions to Discriminating-Reverse Parsingark is virtually pushed onto the parsing stack. Then, locally-canonical DR parsing resumes until sufficient right context is read to resolve the initial conflict. Marks code coverings of the right contexts that are compatible with the actions in conflict. A suboptimal solution for such a coding is p

Automata for Pro-V Topologiesced for the free group by M. Hall, Jr. and by Reutenauer for the free monoid. It is the initial topology defined by all the monoid morphisms from the free monoid into a discrete finite group. For a variety of finite groups ., the pro-. topology is defined in the same way by replacing “group” by “gro

Reachability and Safety in Queue Systemsction) takes one time unit. There is no central control. Note that since . is nondeterministic there are, in general, many computation paths starting from a given initial configuration. We investigate the decidable properties of queue systems. For example, we show that it is decidable to determine,
