Foreword
ETAPS 2002 is the fifth instance of the European Joint Conferences on Theory
and Practice of Software. ETAPS is an annual federated conference that was
established in 1998 by combining a number of existing and new conferences.
Thisyearitcomprisesfiveconferences(FOSSACS,FASE,ESOP,CC,TACAS),
thirteen satellite workshops (ACL2, AGT, CMCS, COCV, DCC, INT, LDTA,
SC,SFEDL,SLAP,SPIN,TPTSandVISS),eightinvitedlectures(notincluding
those that are specific to the satellite events), and several tutorials.
The events that comprise ETAPS address various aspects of the system de-
velopmentprocess,includingspecification,design,implementation,analysisand
improvement. The languages, methodologies and tools which support these ac-
tivities are all well within its scope. Different blends of theory and practice are
represented, with an inclination towards theory with a practical motivation on
one hand and soundly-based practice on the other. Many of the issues involved
in software design apply to systems in general, including hardware systems, and
the emphasis on software is not intended to be exclusive.
ETAPS is a loose confederation in which each event retains its own identity,
with a separate programme committee and independent proceedings. Its format
is open-ended, allowing it to grow and evolve as time goes by. Contributed talks
and system demonstrations are in synchronized parallel sessions, with invited
lectures in plenary sessions. Two of the invited lectures are reserved for “uni-
fying” talks on topics of interest to the whole range of ETAPS attendees. The
aim of cramming all this activity into a single one-week meeting is to create a
strong magnet for academic and industrial researchers working on topics within
its scope, giving them the opportunity to learn about research in related areas,
and thereby to foster new and existing links between work in areas that were
formerly addressed in separate meetings.
ETAPS 2002 is organized by Laboratoire Verimag in cooperation with
Centre National de la Recherche Scientifique (CNRS)
Institut de Math´ematiques Appliqu´ees de Grenoble (IMAG)
Institut National Polytechnique de Grenoble (INPG)
Universit´e Joseph Fourier (UJF)
European Association for Theoretical Computer Science (EATCS)
EuropeanAssociationforProgrammingLanguagesandSystems(EAPLS)
European Association of Software Science and Technology (EASST)
ACM SIGACT, SIGSOFT and SIGPLAN

I would like to express my sincere gratitude to all of these people and orga-
nizations, the programme committee chairs and PC members of the ETAPS
conferences, the organizers of the satellite events, the speakers themselves, and
finally Springer-Verlag for agreeing to publish the ETAPS proceedings. As or-
ganiser of ETAPS’98, I know that there is one person that deserves a special
applause: Susanne Graf. Her energy and organizational skills have more than
compensated for my slow start in stepping into Don Sannella’s enormous shoes
as ETAPS Steering Committee chairman. Yes, it is now a year since I took over
the role, and I would like my final words to transmit to Don all the gratitude
and admiration that is felt by all of us who enjoy coming to ETAPS year after
year knowing that we will meet old friends, make new ones, plan new projects
and be challenged by a new culture! Thank you Don!

Preface
The present volume contains the proceedings of the international conference
FoundationsofSoftwareScienceandComputationStructures(FOSSACS)2002,
held in Grenoble, France, April 10–12, 2002. FOSSACS is an event of the Joint
European Conferences on Theory and Practice of Software (ETAPS).Theprevi-
ousfourFOSSACSconferencestookplaceinLisbon(1998),Amsterdam(1999),
Berlin (2000), and Genova (2001).
FOSSACSpresentspapers,whichofferprogressinfoundationalresearchwith
a clear significance to Software Sciences. Central objects of interest are the al-
gebraic,categorical,logical,andgeometrictheories,models,andmethodswhich
supportthespecification, synthesis, verification, analysis, and transformation of
sequential, concurrent, distributed, and mobile programs and software systems.
Thisvolumecontainsresearchcontributionstoawidespectrumoftopicswithin
this scope, many of which are motivated by recent trends and problems in the
practice of software and information technology.
These proceedings contain 29 papers. The first one accompanies the invited
lecture Semantical Evaluations as Monadic Second-Order Compatible Structure
Transformations delivered by Bruno Courcelle, University of Bordeaux. The
other28arecontributedpapers,selectedfromatotalof67submissions.Iwould
like to sincerely thank all members of the FOSSACS 2002 Program Committee
for the excellent job they did in the difficult selection process. Also I would like
to thank all the sub-referees for their invaluable contributions to this process.
Thanks also to the co-editor of this volume, Uffe H. Engberg, for his assis-
tance in handling and preparing the files for the publisher. And special thanks
to Pawel Sobocinski for his excellent administrative handling of the conference
webpage,theelectronicsubmissions,thereviewing,andthenotificationprocess.
Thanks also to Rich Gerber for allowing us to use his conference management
system START. And finally thanks to the ETAPS 2002 Organizing Commit-
tee chaired by Susanne Graf, and the Steering Committee of ETAPS for their
efficient coordination of all the activities leading up to FOSSACS 2002.
