Previous researchers have suggested the use of “lighthouses” to act as guides in directed state space search. The drawback of using lighthouses is that the user has to manuall...
We propose an algorithm to compute a counterexample of minimal size to some property in a finite state program, using the same space constraints than SPIN. This algorithm uses nes...
Abstract: This paper describes some tools to support formal methods, and conversely some formal methods for developing such tools. We focus on distributed cooperative proving over ...

We describe a new way to construct large subdirectly irreducibles within an equational class of algebras. We use this construction to show that there are forbidden geometries of m...
We propose a programming paradigm that tries to get close to both the semantic simplicity of relational algebra, and the expressive power of unrestricted programming languages. It...
