CoVeCe

A project funded by the ERC, about Coinduction for Verification and Certification.

Code

Formal proofs and libraries

• Graph theory: K4-free = TW2 (Christian Doczkal and Guillaume Combette as main authors).
• Chebyshev rigorous approximations (with Florent Bréhard and Assia Mahboubi).
• Coinduction all the way up: a new library for -impredicative- coinduction in Coq.
• Relation Algebra and KAT in Coq (includes a tactic for deciding Kleene algebras with Tests).
• Certification of robust reconfiguration algorithms (joint work with Fabienne Boyer and Olivier Gruber).
• Algebraic Tools for Binary Relations (includes a tactic for deciding Kleene algebras---joint work with Thomas Braibant).
• Plugin for rewriting modulo associativity and commutativity (joint work with Thomas Braibant).
• Formalisation of the entire ICALP'05 article.
• Certified compiler from recursive functions to Minski machines.

Algorithms

• Symbolic Algorithms for Language Equivalence and Kleene Algebra with Tests (KAT).
• A new algorithm for NFA language equivalence.
• Checking must testing using bisimulations up to congruence.
• Optimised proof search algorithm for cyclic linear logic.

Abstract Machines

• Distributed implementation of an abstract machine for Safe Ambient.
• Graphical machine for interpreting various notions of Mobile Ambients in a funny way.
