Preface
This volume contains the papers presented at the 25th Jubilee Edition of the Interna-
tional Conference on Automated Deduction (CADE-25), held August 1–7, 2015, in
Berlin, Germany. CADE is the major forum for the presentation of research in all
aspects of automated deduction, including foundations, applications, implementations,
and practical experience.
The Program Committee (PC) accepted 36 papers (24 full papers and 12 system
descriptions) out of a total of 85 submissions. Each submission was reviewed by at
leastthreePCmembersorexternalreviewersappointedbythePCmembersincharge.
The program also included invited lectures given by Ulrich Furbach (University of
Koblenz, Germany) and Edward Zalta (Stanford University, USA). In addition,
MichaelGenesereth(StanfordUniversity,USA)gaveaninvitedlectureinconjunction
with the co-located event RuleML (9th International Web Rule Symposium).
To celebrate the 25th jubilee edition of the conference, additional invited speakers
were featured at several events. A Special Session on the Past, Present, and Future of
Automated Deduction included talks by Ursula Martin (University of Oxford, UK),
Frank Pfenning (Carnegie Mellon University, USA), David Plaisted (University of
NorthCarolinaatChapelHill,USA),andAndreiVoronkov(UniversityofManchester,
UK). Also, the conference reception and the banquet dinner featured speakers Wolf-
gang Bibel and Jörg Siekmann. In addition, the program was enriched by several
affiliated events that took place before the main conference. These events included
eight workshops, seven tutorials, three competitions, and one poster event.
During the conference, the Herbrand Award for Distinguished Contributions to
Automated Reasoning was presented to Andrei Voronkov in recognition of his
numerous theoretical and practical contributions to automated deduction and the
developmentoftheaward-winningVampiretheoremprover.TheSelectionCommittee
fortheHerbrandAwardconsistedoftheCADE-25Program Committeemembers,the
trustees of CADE Inc., and the Herbrand Award winners of the last ten years.
The Best Paper Award was conferred to Vijay D’Silva (Google, Inc., USA) and
Caterina Urban (École Normale Supérieure, France) for their paper entitled “Abstract
Interpretation as Automated Deduction.” In addition, the first Thoralf Skolem Awards
were conferred this year to reward CADE papers that have passed the test of time by
being most influential papers in the field:
CADE-20 (2005) Nominal techniques in Isabelle/HOL by Christian Urban and
Christine Tasson: The first paper showing how to use nominal techniques to deal
with bound variables in higher-order theorem provers.
CADE-14 (1997) SATO: An Efficient Propositional Prover by Hantao Zhang: For
its seminal contribution to the design and implementation of novel techniques,
includinglazydatastructuresandcleverBooleanconstraintpropagationthatcaused
a step change in the area and deeply influenced later systems.
VI Preface
CADE-8(1986)Commutation,Transformation,andTerminationbyLeoBachmair
and Nachum Dershowitz: For laying the foundations of today’s termination
theorem-proving techniques.
CADE-0-1 (1968 and 1975) The mathematical language AUTOMATH, its usage,
and some of its extensions by N.G. de Bruijn: For his landmark and remarkable
contribution to the design and implementation of higher-order theorem provers.
Also, several students received Woody Bledsoe Travel Awards, thus named to
remember the late Woody Bledsoe, funded by CADE Inc. to sponsor student
participation.
ManypeoplecontributedtomakingCADE-25asuccess.Weareverygratefultothe
membersoftheProgramCommitteeandtheexternalreviewersforcarefullyreviewing
and evaluating papers. CADE-25 would not have been possible without the dedicated
work of the Organizing Committee, headed by Conference Chair Christoph
Benzmüller. Many thanks also go to Workshop, Tutorial, and Competition Co-chairs
Jasmin Blanchette and Andrew Reynolds, and to Publicity and Web Chair Julian
Röder.OnbehalfoftheProgramCommittee,wealsothankalltheinvitedspeakersfor
their contribution to the success of this jubilee edition. We also acknowledge the
important contributions of the workshop organizers, tutorial speakers, competition
organizers, and poster event organizer. Thanks also go to Andrei Voronkov and the
development team of the EasyChair system. Last, but not least, we thank all authors
who submitted papers to CADE-25 and all participants of the conference.
CADE-25 received support from many organizations. On behalf of all organizers,
we thank the German Research Foundation, DFG, for supporting the special session,
and the European Coordinating Committee for Artificial Intelligence (ECCAI) for
supporting the invited talk given by Ulrich Furbach. We also gratefully acknowledge
supportfromFreieUniversitätBerlin,theArtificialIntelligenceJournal,andMicrosoft
Research.
