The 5th Workshop on Reachability Problems will be hosted by  DISI (Dip. di Informatica e Scienze dell'Informazione),  Universita' di Genova, Italy.

The Reachability Workshop is specifically aimed at gathering together scholars from diverse disciplines and backgrounds interested in reachability problems that appear in
- Algebraic structures
- Computational models
- Hybrid systems
- Logic
- Verification

Invited Speakers:
- Krishnendu Chatterjee, IST Austria
- Bruno Courcelle, LABRI, Bordeaux
- Joost-Pieter Katoen, RWTH, Aachen
- Jean-Francois Raskin, Univerite' Libre de Bruxelles

Submissions:
Papers presenting original contributions related to reachability problems in different computational models and systems are being sought.
Topics of interest include (but are not limited to):
Reachability for infinite state systems, rewriting systems; Reachability analysis in counter/ timed/ cellular/ communicating automata; Petri-Nets; computational aspects of semigroups, groups and rings; Reachability in dynamical and hybrid systems; frontiers between decidable and undecidable reachability problems; complexity and decidability aspects; predictability in iterative maps and new computational paradigms

Authors are invited to submit a draft of a full paper with at most 12 pages (in LaTeX, formatted according to LNCS guidelines) via the conference web page.
Proofs omitted due to space constraints must be put into an appendix to be read by the program committee members at their discretion.
Submissions deviating from these guidelines risk rejection.
Electronic submissions should be formatted in postscript or pdf. Simultaneous submission to other conferences or workshops with published proceedings is not allowed.

Important Dates:
Submission deadline: 10 May, 2011
Notification: 28 June, 2011
Final version: 5 July, 2011
Conference: 28-30 September, 2011

Proceedings:
The Conference Proceedings will be published as the volume of the  Springer Verlag LNCS (Lecture Notes in Computer Science) series and distributed at the Conference. We plan also to publish selected papers in a special issue of a high quality journal following the regular referee procedure.
