    From determinism, non-determinism and alternation to recursion schemes for P, NP and Pspace (Invited Talk)

    No full text
    Our goal is to approach the classes of computational complexity P, NP, and Pspace in a recursion-theoretic manner. Here we emphasize the connection between the structure of the recursion schemes and the underlying models of computation

    Logic and Automata

    Get PDF
    Mathematical logic and automata theory are two scientific disciplines with a fundamentally close relationship. The authors of Logic and Automata take the occasion of the sixtieth birthday of Wolfgang Thomas to present a tour d'horizon of automata theory and logic. The twenty papers in this volume cover many different facets of logic and automata theory, emphasizing the connections to other disciplines such as games, algorithms, and semigroup theory, as well as discussing current challenges in the field

    Arrows for knowledge-based circuits

    No full text
    Knowledge-based programs (KBPs) are a formalism for directly relating agents' knowledge and behaviour in a way that has proven useful for specifying distributed systems. Here we present a scheme for compiling KBPs to executable automata in finite environments with a proof of correctness in Isabelle/HOL. We use Arrows, a functional programming abstraction, to structure a prototype domain-specific synchronous language embedded in Haskell. By adapting our compilation scheme to use symbolic representations we can apply it to several examples of reasonable size

    This open access book constitutes the proceedings of the 25th International Conference on Foundations of Software Science and Computational Structures, FOSSACS 2022, which was held during April 4-6, 2022, in Munich, Germany, as part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2022. The 23 regular papers presented in this volume were carefully reviewed and selected from 77 submissions. They deal with research on theories and methods to support the analysis, integration, synthesis, transformation, and verification of programs and software systems

    26. Theorietag Automaten und Formale Sprachen 23. Jahrestagung Logik in der Informatik: Tagungsband

    Get PDF
    Der Theorietag ist die Jahrestagung der Fachgruppe Automaten und Formale Sprachen der Gesellschaft fĂŒr Informatik und fand erstmals 1991 in Magdeburg statt. Seit dem Jahr 1996 wird der Theorietag von einem eintĂ€gigen Workshop mit eingeladenen VortrĂ€gen begleitet. Die Jahrestagung der Fachgruppe Logik in der Informatik der Gesellschaft fĂŒr Informatik fand erstmals 1993 in Leipzig statt. Im Laufe beider Jahrestagungen finden auch die jĂ€hrliche Fachgruppensitzungen statt. In diesem Jahr wird der Theorietag der Fachgruppe Automaten und Formale Sprachen erstmalig zusammen mit der Jahrestagung der Fachgruppe Logik in der Informatik abgehalten. Organisiert wurde die gemeinsame Veranstaltung von der Arbeitsgruppe ZuverlĂ€ssige Systeme des Instituts fĂŒr Informatik an der Christian-Albrechts-UniversitĂ€t Kiel vom 4. bis 7. Oktober im Tagungshotel Tannenfelde bei NeumĂŒnster. WĂ€hrend des Tre↔ens wird ein Workshop fĂŒr alle Interessierten statt finden. In Tannenfelde werden ‱ Christoph Löding (Aachen) ‱ TomĂĄs Masopust (Dresden) ‱ Henning Schnoor (Kiel) ‱ Nicole Schweikardt (Berlin) ‱ Georg Zetzsche (Paris) eingeladene VortrĂ€ge zu ihrer aktuellen Arbeit halten. DarĂŒber hinaus werden 26 VortrĂ€ge von Teilnehmern und Teilnehmerinnen gehalten, 17 auf dem Theorietag Automaten und formale Sprachen und neun auf der Jahrestagung Logik in der Informatik. Der vorliegende Band enthĂ€lt Kurzfassungen aller BeitrĂ€ge. Wir danken der Gesellschaft fĂŒr Informatik, der Christian-Albrechts-UniversitĂ€t zu Kiel und dem Tagungshotel Tannenfelde fĂŒr die UnterstĂŒtzung dieses Theorietags. Ein besonderer Dank geht an das Organisationsteam: Maike Bradler, Philipp Sieweck, Joel Day. Kiel, Oktober 2016 Florin Manea, Dirk Nowotka und Thomas Wilk
