International Research Visitors

Visits of International Scientists

• Ilina Stoilkovska

  • Date: 1 September – 31 October

  • Institution: TU Wien (Austria)

  • Host: Stephan Merz

  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

  • Date: 1 May 2016 – 30 April 2017

  • Institution: JAIST

  • Host: Pascal Fontaine

  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 Olav Candasamy

  • Date: 1 March – 31 July

  • Institution: Université de Lorraine (Erasmus Mundus DESEM)

  • Host: Dominique Méry

  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

  • Date: 1 March – 31 July

  • Institution: École Polytechnique

  • Host: Stephan Merz

  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

  • Date: 1 March – 31 August

  • Institution: Université de Lorraine (Erasmus Mundus DESEM)

  • Host: Stephan Merz

  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.
