The Spin 2002 Workshop

The Spin 2002 workshop will be held April 11-13 2002 in Grenoble, France, as a satellite event of ETAPS 2002, which is held from April 6-14 2002 at the same location.

The invited speakers for our workshop are: Ed Clarke (CMU, USA), together with Allen Emerson and concurrently with Joseph Sifakis in France, one of the founders of logic model checking, and Patrick Cousot (ENS, Paris), famous for his pioneering work in abstract interpretation.

Note the submission deadline for the workshop: December 12, 2001. The call for papers is available at: http://tele.informatik.uni-freiburg.de/spin2002/

The Spin Workshops have obtained the sponsorship of ACM SIGSOFT, and the workshop now has a general chair (Moshe Vardi), a charter, a steering committee and an advisory committee. For more details, e.g. the initial membership of the two committees, see the charter description at http://tele.informatik.uni-freiburg.de/spin-charter.html.

Related tools: HF-Spin

HF-SPIN is an experimental extension of Spin that uses heuristic search techniques for finding errors faster. The most practical use of this tool is that it can use an error trail file to reproduce the error state and use this information to perform a search for finding a shorter trail. At the moment HSF-SPIN allows this only for safety errors, but we are working on the extension for liveness. A first distribution of this tool is available at: http://www.informatik.uni-freiburg.de/~lafuente/hsf-spin For mode details contact Alberto Lafuente at [email protected]
