ETAPS Foreword
Welcome to the proceedings of ETAPS 2017, which was held in Uppsala! It was the
first time ever that ETAPS took place in Scandinavia.
ETAPS 2017 was the 20th instance of the European Joint Conferences on Theory
and Practice of Software. ETAPS is an annual federated conference established in
1998, and consists offive conferences: ESOP, FASE, FoSSaCS, TACAS, and POST.
Each conference has its own Program Committee (PC) and its own Steering Com-
mittee. The conferences cover various aspects of software systems, ranging from
theoretical computer science to foundations to programming language developments,
analysis tools, formal approaches to software engineering, and security. Organizing
these conferences in a coherent, highly synchronized conference program enables
participation in an exciting event, offering the possibility to meet many researchers
working in different directions in the field and to easily attend talks of different con-
ferences. Before and after the main conference, numerous satellite workshops take
place and attract many researchers from all over the globe.
ETAPS 2017 received 531 submissions in total, 159 of which were accepted,
yielding an overall acceptance rate of 30%. I thank all authors for their interest in
ETAPS, all reviewers for their peer reviewing efforts, the PC members for their con-
tributions,andinparticularthePC(co-)chairsfortheirhardworkinrunningthisentire
intensive process. Last but not least, my congratulations to all authors of the accepted
papers!
ETAPS 2017 was enriched by the unifying invited speakers Kim G. Larsen (Aal-
borg University, Denmark) and Michael Ernst (University of Washington, USA), as
wellastheconference-specificinvitedspeakers(FoSSaCS)JoelOuaknine(MPI-SWS,
Germany,andUniversityofOxford,UK)and(TACAS)DinoDistefano(Facebookand
Queen Mary University of London, UK). In addition, ETAPS 2017 featured a public
lecture by Serge Abiteboul (Inria and ENS Cachan, France). Invited tutorials were
offered by Véronique Cortier (CNRS research director at Loria, Nancy, France) on
security and Ken McMillan (Microsoft Research Redmond, USA) on compositional
testing.Mysincerethankstoallthesespeakersfortheirinspiringandinterestingtalks!
ETAPS2017tookplaceinUppsala,Sweden,andwasorganizedbytheDepartment
of Information Technology of Uppsala University. It was further supported by the
following associations and societies: ETAPS e.V., EATCS (European Association for
Theoretical Computer Science), EAPLS (European Association for Programming
LanguagesandSystems),andEASST(EuropeanAssociationofSoftwareScienceand
Technology). Facebook, Microsoft, Amazon, and the city of Uppsala financially sup-
ported ETAPS 2017. The local organization team consisted of Parosh Aziz Abdulla
(generalchair),WangYi,BjörnVictor,KonstantinosSagonas,MohamedFaouziAtig,
Andreina Francisco, Kaj Lampka, Tjark Weber, Yunyun Zhu, and Philipp Rümmer.
The overall planning for ETAPS is the main responsibility of the Steering Com-
mittee, and in particular of its executive board. The ETAPS Steering Committee

Preface
This volume contains the papers presented at the 20th International Conference on
FoundationsofSoftwareScienceandComputationStructures(FoSSaCS2017),which
was held April 24–27, 2017, in Uppsala, Sweden. The conference is dedicated to
foundationalresearchwithaclearsignificanceforsoftwarescienceandbringstogether
research on theories and methods to support the analysis, integration, synthesis,
transformation, and verification of programs and software systems.
In addition to an invited talk by Joël Ouaknine (MPI-SWS Saarbrücken and
University of Oxford) on “Fundamental Algorithmic Problems and Challenges in
Dynamical and Cyber-Physical Systems,” the program consisted of 32 contributed
papers,selectedfromamong101submissions.Eachsubmissionwasassessedbythree

was used to handle the submissions, to conduct the electronic Program Committee
discussions, and to assist with the assembly of the proceedings.
We wish to thank all the authors who submitted papers for consideration, the
members of the Program Committee for their conscientious work, and all additional
reviewers who assisted the Program Committee in the evaluation process. Finally, we
wouldliketothanktheETAPSorganizationforprovidinganexcellentenvironmentfor
FoSSaCS, other conferences, and workshops.
