Dear all, The next talk in the IARCS Verification Seminar Series will be given by Jan Křetínský, a professor for Formal Methods for Software Reliability at the Technical University of Munich. The talk is scheduled on Tuesday, October 15, at 1900 hrs IST (add to Google calendar <https://calendar.google.com/calendar/event?action=TEMPLATE&tmeid=NWN0OWYwcTk3dmZkcjQ1bWp2cDJsYXM2ZjMgdnNzLmlhcmNzQG0&tmsrc=vss.iarcs%40gmail.com> ). The details of the talk can be found on our webpage ( https://fmindia.cmi.ac.in/vss/), and also appended to the body of this email. The Verification Seminar Series, an initiative by the Indian Association for Research in Computing Science (IARCS), is a monthly, online talk-series, broadly in the area of Formal Methods and Programming Languages, with applications in Verification and Synthesis. The aim of this talk-series is to provide a platform for Formal Methods researchers to interact regularly. In addition, we hope that it will make it easier for researchers to explore newer problems/areas and collaborate on them, and for younger researchers to start working in these areas. All are welcome to join.

Its applications range from cases where the game's huge size prohibits rigorous approaches, over increasing scalability of rigorous synthesis, to explainability of synthesized controllers. We discuss the advantages and caveats of these new avenues in synthesis. On the technical level, we describe (i) how to reflect the highly structured logical information in game's states, the so-called semantic labelling, coming from the recent LTL-to-automata translations, and (ii) to do so by learning from previously solved games, bringing the solution process closer to human-like reasoning. Bio: After PhD from Technical University of Munich in 2013 and from Masaryk University Brno in 2014, Jan Křetínský was a research fellow at IST Austria and since 2015 a professor at TU Munich, getting tenure there. While still affiliated, he has recently moved to MU Brno. His main focus is basic research in verification, control and explainability of complex systems. Since 2013 he has been advocating and pioneering the use of AI and ML in verification.
