Valentin Montmirail: "A Recursive Shortcut for CEGAR: Application to the Modal Logic K Satisfiability Problem"
Counter-Example-Guided Abstraction Refinement (CEGAR) has been very successful in model checking.
Since then, it has been applied to many different problems. It is especially proved to be a highly successful practical approach for solving the PSPACE complete QBF problem. In this paper, we propose a new CEGAR-like approach for tackling PSPACE complete problems that we call RECAR (Recursive Explore and Check Abstraction Refinement). We show that this generic approach is sound and complete. Then we propose a specific implementation of the RECAR approach to solve the modal logic K satisfiability problem. We implemented both CEGAR and RECAR approaches for the modal logic K satisfiability problem within the solver MoSaiC. We compared experimentally those approaches to the state-of-the-art solvers for that problem. The RECAR approach outperforms the CEGAR one for that problem and also compares favorably against the state-of-the-art on the benchmarks considered.

Emmanuel Filliot, Université Libre de Bruxelles: "Automata, Logic and Algebra for Word Transductions"

This talk will survey old and recent results about word transductions, i.e. functions mapping (finite) words to words. Connections between automata models (transducers), logic and algebra will be presented. Starting with rational functions, defined by (one-way) finite transducers, and the canonical model of bimachines introduced by Reutenauer and Schützenberger, the talk will also target the more expressive class of functions defined by two-way transducers and their equivalent MSO-based formalism.
