PERR 2019
   3rd Workshop on Program Equivalence and Relational Reasoning

A workshop at ETAPS 2019 in Prague
(European Joint Conferences of Theory & Practice of Software)

Important dates:
Submission deadline  Fri 8 Feb 2019 (extended)
Notification Fri 1 Mar 2019
Workshop Sat 6 Apr 2019


Call for Papers

PERR is an annual international workshop dedicated to the formal
verification of program equivalence and related relational
problems. It is the 3rd in a series of meetings that bring together
researchers from different areas interested in equivalence and related
questions. PERR 2019 will be held as satellite workshop of ETAPS
(http://www.etaps.org/).

Program equivalence is arguably one of the most interesting and at the
same time important problems in formal verification. It is a
cross-cutting topic that has attracted the interest of several
research communities: the field of denotational (game) semantics,
deductive software verification, bounded model checking, specification
inference, software evolution and regression testing, etc.


Topics

The goal of the workshop is to bring researchers of the different
fields in touch and to stipulate an exchange of ideas leading to
forging a community working on PERR. It welcomes contributions from
the topics mentioned above but is also open to new questions regarding
program equivalence. This includes related research areas of
relational reasoning like program refinement or the verification of
hyperproperties, in particular of secure information flow.  Areas of
interest include (but are not limited to):

.regression verification
.program equivalence
.equivalence of higher order programs
.product programs, relational calculi
.verification of hyperproperties
.program refinement, refinement calculus
.specification of differences between programs
.inferring semantic differences between programs
.transformation validation
.correct compiler transformations
.automata bisimulation
.code equivalence checking in teaching and marking

This is an informal workshop that welcomes work in progress, overviews
of more extensive work, programmatic or position papers and tool
presentations.

The workshop will have informal proceedings, posted on its webpage,
and speakers will be asked to consider submitting papers towards a
post-proceedings volume.


Submission Instructions

Please submit an abstract (this can be in the form of 1-2 pages of
text, or a paper of no more than 15 pages) of your proposed talk on
the EasyChair submission page below. Submissions will be reviewed by
at least 2 PC members and feedback will be provided.

Highlights of Logic, Games and Automata (HIGHLIGHTS 2017)

London, 12-15 SEPTEMBER 2017

http://highlights-conference.org

1st CALL FOR PRESENTATIONS



HIGHLIGHTS 2017 is the fifth conference on Highlights of Logic, Games 
and Automata that aims at integrating the community working in these 
fields. Papers from these areas are dispersed across many conferences, 
which makes them difficult to follow. A visit to the Highlights 
conference should offer a wide picture of the latest research in the 
field and a chance to meet everybody in the community, not just those 
who happen to publish in one particular proceedings volume. We encourage 
you to attend and present your best work, be it already published or 
not, at the Highlights conference.


Representative areas include, but are not restricted to: logic and 
finite model theory, automata theory, games for logic and verification.


The conference itself is three days long (Sep. 13-15) and it is preceded 
by the Highlights tutorial day (Sep. 12). The participation costs will 
be modest (with a discount for students and post-docs) and London is 
very easy to reach.


The contributed talks are around ten minutes. Ideally, they let 
participants learn something new, and enable them to understand the 
objective/problem/question and the result, and to get an idea of the 
technique.


The program will further offer three invited talks:

+ Mikolaj Bojanczyk: Recognisability equals MSO definability for graphs 
of bounded treewidth.


+ Sanjay Jain: Quasi Polynomial and FPT algorithms for parity games

+ Hung Ngo: Shannon-type inequalities, submodular width, and disjunctive 
datalog


two invited sessions, organised by:

+ Patricia Bouyer: Games played on graphs: quantitative games, games 
with multi-objectives, non-zero sum games


+ Alexandra Silva: Model learning, automata and its applications

and two tutorials:

+ Veronique Cortier: Verification of security protocols

+ Damien Pous: Coinduction up to and automata algorithms

The submission deadline is

*** JUNE 2, 2017***

Notifications will be sent by June 12, 2017.

Registration will be possible until August 7, 2017.

You submit a proposal for a presentation, not a paper. Hence, 
submissions should have a single author, who is the speaker. Since we 
expect you to present your favourite result of the year, there should be 
at most one submission per speaker. The abstract, of 1-2 pages, may 
include a list of coauthors. There are no formal proceedings and we 
encourage submission of work presented elsewhere. Submissions are 
possible through  https://easychair.org/conferences/?conf=highlights17.


The instructions and detailed information about Highlights 2017 are 
available at http://highlights-conference.org.

[ The Types Forum (announcements only),
http://lists.seas.upenn.edu/mailman/listinfo/types-announce ]

PhD Studentship in Semantics and Verification of Heterogeneous Programs

Applications are invited for a fully-funded PhD studentship within the 
Theory Group at Queen Mary University of London, as part of a project 
which aims to develop a unified semantic framework for heterogeneous 
software systems and apply it to compositional software compilation and 
verification. Cloud computing and heterogeneous computing are widely 
acknowledged to dominate the software landscape in the foreseeable 
future. The recent work on System-Level Games provides a semantic 
framework for modelling low-level code interactions involving resources 
shared between a program and its environment. This project will apply 
the framework for deriving compositional analysis techniques for the 
compilation and verification of heterogeneous programs.


All nationalities are eligible to apply for this studentship, which will 
start in October 2016. The studentship is for three years, and covers 
student fees as well as a tax-free stipend of £16,057 per annum. 
Candidates must have a 2:1 degree or equivalent, and/or a good MSc 
Degree, in Computer Science or a related discipline. The ideal candidate 
should be creative and motivated in the studying of semantics and 
verification of programming languages. Good coding skills will be an 
advantage, and applicants will have at least good knowledge of 
programming languages such as C/C++, Java, Python, OCaml. Analytical and 
good communication skills are also welcome.


The PhD supervisor will be Dr Nikos Tzevelekos. The project will be 
based in the School of Electronic Engineering and Computer Science 
(EECS), and the student will join a world-leading centre for research on 
logical methods for reasoning about computer systems in the Theory Group 
(http://theory.eecs.qmul.ac.uk/). The position will be integrated in the 
EPSRC project "System-Level Game Semantics: A unifying framework for 
composing systems", which is in collaboration with the University of 
Birmingham. Informal enquiries about the studentship can be made by 
email to Dr Tzevelekos (nikos.tzevele...@qmul.ac.uk).


To apply, please follow the on-line process at
www.qmul.ac.uk/postgraduate/applyresearchdegrees/
click on the list of Research Degree Subjects, select "Computer 
Science", and follow the instructions on the right-hand side of the web 
page. Please note that instead of the Research Proposal we request a 
Statement of Research Interests. Your statement should answer two
