IARCS Verification Seminar Series -- Talk by Thejaswini Raghavan on Jan. 23 at 1900 hrs IST

by VSS IARCS

Dear all, The next talk in the IARCS Verification Seminar Series will be given by Thejaswini Raghavan, a postdoctoral researcher at IST Austria. The talk is scheduled on Tuesday, Jan. 23, at 1900 hrs IST (add to Google calendar <https://calendar.google.com/calendar/event?action=TEMPLATE&tmeid=MjQxam5sb2…> ). 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. Best regards, Akash, Deepak, Madhukar, Srivathsan ============================================================= Title: Solving Rabin games using Colourful Universal Trees Meeting Link: https://us02web.zoom.us/j/89164094870?pwd=eUFNRWp0bHYxRVpwVVNoVUdHU0djQT09 (Meeting ID: 891 6409 4870, Passcode: 082194) Abstract: To solve Church's synthesis problem for omega-regular specifications, represented by non-deterministic Buechi automata, there are two polynomial-time equivalent approaches: either reduce it to the emptiness problem for Rabin tree automata or solve a Rabin game. In this talk, we will see how one can solve Rabin games faster with an improvement by a super quadratic dependence on the number of Rabin pairs from the currently best known run time obtained by converting a Rabin game into a parity game, while simultaneously improving its exponential space requirement. Our main technical ingredient is a characterisation of progress measures for Rabin games using colourful trees and a combinatorial construction of succinctly-represented, universal colourful trees. Colourful universal trees are generalisations of universal trees used by Jurdzinski and Lazic (2017) to solve parity games, as well as of Rabin progress measures of Klarlund and Kozen (1991). Further, we will also discuss lower bounds for solving Rabin games that show that our algorithm is tight subject to the exponential time hypothesis, reproving a result of Calude et al. (2022). The first part of the talk is based on joint work with Rupak Majumdar and Irmak Saglam, accepted at TACAS 2024 and the last part about the lower bounds is based on joint work with Antonio Casares, Marcin Pilipczuk, Michal Pilipczuk, Ueverton S. Souza, published at SOSA 2024. Bio: Thejaswini Raghavan is a postdoctoral researcher at IST Austria in the group headed by Thomas A. Henzinger. She did her Ph.D. under the supervision of Marcin Jurdzinski at the University of Warwick. Prior to that, she did her B.Sc. (Hons.) in Mathematics and Computer Science and M.Sc. in Computer Science from Chennai Mathematical Institute (CMI). Her research interests broadly lie in Logic, Automata, Games, and Verification.

Internship opportunity for formal methods PhD students at GE Aerospace India

by Supratik Chakraborty

I am posting this on behalf of Samhitha Palanganda Poonacha (GE Aerospace) <samhitha.poonacha(a)ge.com>. Please contact Samhitha directly for any queries. ===================== The current V&V process we have for our aircraft engine controls software is fairly involved and manual. The European regulating agencies have mandated a change GE’s V&V process which means much more manual effort for us going forward each time we want to certify our engine controls software. The Research team at Bangalore is currently involved in one such V&V exercise and have identified many opportunities where we can find the right balance between innovation and deploying formal methods that can significantly improve the productivity for the team. We are looking for an intern with a formal methods background who is curious to see what happens to automation in a very complex set up, an aircraft engine, and some of the real-world challenges we need to deal with when designing solutions. To give you an idea: Number of requirements in thousands and written up by a wide variety of people where for many, English is not the primary language, this alone can make things very challenging. The work would involve both supporting some of the V&V activities as well as designing proof-of-concepts for proposed process refinements. Exposure to engineering challenges while being part of a multi-disciplinary unit will be some things the intern can stand to gain. The team itself has folks from a variety of technical backgrounds and additionally solving an array of AI/NLP applications for GE Aerosapce. Ideally we would like someone who can work with us for ~6 months. Job Posting: https://ge.wd5.myworkdayjobs.com/GE_ExternalSite/job/Bengaluru/Research-Int… We can also make the option of a post-doc possible in case someone is interested to see what applied research at GE Aerospace looks like.
