| Résumé: |
Hacking Nondeterminism with Induction and Coinduction |
| Description: |
Damien Pous Finite automata are used in a wide range of verification problems.
We introduce "bisimulation up to congruence" as a technique for
proving language equivalence of non-deterministic finite automata.
Exploiting this technique, we devise an optimisation of the classical
algorithm by Hopcroft and Karp which, as we show, is exploiting a
weaker "bisimulation up to equivalence" technique. The resulting
algorithm can be exponentially faster than the recently introduced
"antichain algorithms". |
