International Research Visitors
Visits of International Scientists
-
Ilina is a PhD student at TU Wien, Austria, and works on tailored abstractions for the parameterized verification of fault-tolerant distributed algorithms. During her stay in Nancy, she worked on a formal soundness proof of her abstractions in the TLA+ Proof System.
-
Tung Vu Xuan is a PhD student at JAIST, Japan. He is visiting VeriDis in the context of the KANASA project. He works mainly on Interval Constraint Propagation (ICP), a heuristic but powerful method for satisfiability checking of non-linear arithmetic (NLA) constraints. During his stay, we investigate techniques to combine ICP with decision procedures for NLA within an SMT context.
Internships
-
Anders Candasamy analyzed a hemodialysis case study using Event-B. Besides developing the formal model, he also reflected on the modeling process and proposed several methodological improvements.
-
Matthieu Lequesne worked on translating formulas in a core sublanguage of TLA+ to the input format of Nunchaku (section 6.1), with the aim of producing (counter)models for TLA+ proof obligations.
-
Weichung Shaw worked on formalizing a correctness proof of the Raft consensus algorithm [50] in TLA+. He proved several fundamental lemmas and documented several methodological issues with the use of TLAPS.
