This article surveys fundamental and applied aspects of symmetry in system models, and of
symmetry reduction methods used to counter state explosion in model checking, an …

In this paper, we provide a survey of the different analysis techniques that are provided for
the modeling language Rebeca. Rebeca is designed as an imperative actor-based …

The size of formal models is steadily increasing and there is a demand from industrial users
to be able to use expressive temporal query languages for validating and exploring high …

TLA+ and B share the common base of predicate logic, arithmetic and set theory. However,
there are still considerable differences, such as very different approaches to typing and …

We present a new animation and model checking tool for CSP. The tool covers the CSP-M
language, as supported by existing tools such as fdr and probe. Compared to those tools, it …

We provide a detailed description of refinement in Event-B, both as a contribution in itself
and as a foundation for the approach to simultaneous animation of multiple levels of …

A lot of techniques try to improve the performance of explicit state model checking. Some
techniques, like partial order reduction, are hard to apply effectively to high-level models …

Rebeca is an actor-based language with formal semantics which is suitable for modeling
concurrent and distributed systems and protocols. Due to its object model, partial order and …

The state-based formal methods B and TLA+ share the common base of predicate logic,
arithmetic and set theory. However, there are still considerable differences, such as the way …

La méthode B, ainsi que sa progéniture Event-B, sont des méthodes formelles utilisées pour
le développement de systèmes informatiques dont l'exactitude doit être formellement …
