[Lrde Annonce] New publication: Generic Emptiness Check for Fun and Profit (ATVA'19)

I'm happy to announce the the following article has been accepted in to the 17th International Symposium on Automated Technology for Verification and Analysis (ATVA'19), to be held on October 27-31, 2019 in Taipei, Taiwan. Generic Emptiness Check for Fun and Profit Christel Baier (1), František Blahoudek (2), Alexandre Duret-Lutz (3), Joachim Klein (1), David Müller (1), and Jan Strejček (4) (1) Technische Universität Dresden, Germany (2) University of Mons, Belgium (3) LRDE, EPITA, Le Kremlin-Bicêtre, France (4) Masaryk University, Brno, Czech Republic We present a new algorithm for checking the emptiness of ω-automata with an Emerson-Lei acceptance condition (i.e., a positive Boolean formula over sets of states or transitions that must be visited infinitely or finitely often). The algorithm can also solve the model checking problem of probabilistic positiveness of MDP under a property given as a deterministic Emerson-Lei automaton. Although both these problems are known to be NP-complete and our algorithm is exponential in general, it runs in polynomial time for simpler acceptance conditions like generalized Rabin, Streett, or parity. In fact, the algorithm provides a unifying view on emptiness checks for these simpler automata classes. We have implemented the algorithm in Spot and PRISM and our experiments show improved performance over previous solutions. https://www.lrde.epita.fr/wiki/Publications/baier.19.atva -- Alexandre Duret-Lutz
