Feel free to spread this call for PhD applications as you see fit. The deadline is in roughly two weeks.
PHD POSITION ON “CONCURRENCY, LOGIC, AND TYPE SYSTEMS“
(Posted: August 31, 2018)
University of Groningen, The Netherlands
We are searching for one four-year PhD position on the topics of concurrency, logic, type systems, and programming languages.
You will contribute to rigorously comparing different type systems for message-passing programs, such as session types.
These comparisons will use as reference a correspondence known as "propositions as sessions", which connects concurrency and logic in the style of the well-known Curry-Howard correspondence.
We will use the resulting comparisons to streamline existing type systems, and to guide the development of verification tools for message-passing programs.
Your PhD research will be embedded in the project "Unifying Correctness for Communicating Software", a VIDI career grant recently awarded to Dr. Jorge A. Perez by the NWO (Netherlands Organization for Scientific Research).
As such, you will join a dynamic, quickly growing research group; within the project, you will collaborate with research partners both in the Netherlands (e.g., at CWI Amsterdam) and abroad.
- Qualifications
You have an MSc degree (or equivalent) in Computer Science, Logic, Mathematics, or Artificial Intelligence, and experience in at least one, preferably two or more, of the following:
• Semantics of programming languages
• Program verification, type systems, and/or typed programming languages
• Concurrency theory and/or process calculi
• The Curry-Howard isomorphism ("propositions as types")
• Modal/substructural logics and (their) proof theory
Female candidates are encouraged to apply.
- Application and Additional Information

Shortest-path algorithms applied to software engineering: A tale of cross fertilization within CS
These days, it looks as if many of us are supposed to undertake, or are expected to promise to carry out, interdisciplinary research. However, I have sometimes witnessed first-hand a lack of curiosity even to cross the (often artificial) boundaries between areas of research within (theoretical) computer science and/or mathematics. This conservative attitude is reasonable at times, and at various stages of one's academic career, and is partly justified by the pressure to produce research output that most of us feel. I freely admit, though, that I felt a bit uneasy when a colleague from "volume A TCS" told me at an ICALP conference that he was not going to attend an invited talk delivered by a "volume B researcher" because that would be like going to a talk in the life sciences. (By the way, that invited talk was excellent and was delivered by a charismatic scientist. The colleague in question missed an intellectual treat.)
Perhaps naively, I feel that one of the reasons why we are in academia is that we are intellectually curious and that we should try to explain what we do to one another at least across the various disciplines within CS. Hence, I was very pleased to see this paper, which will appear in the prestigious IEEE Transactions on Software Engineering (behind the usually hefty paywall of the IEEE, alas). The paper stems from discussions between Mattia D'Emidio (a researcher in algorithmics) and Ludovico Iovino (a researcher in software engineering) who were sharing a basement office at the Gran Sasso Science Institute at the time. Those exchanges of ideas led eventually to the development of a framework that uses classic shortest-path algorithms in the selection of optimal chains of model transformations in model-driven SE. More specifically, those colleagues of mine show how to reduce the problem of computing chains of model transformations
that maximize the coverage to a shortest-path problem on weighted graphs. Moreover, they evaluate the practical effectiveness of the proposed approach by applying their automated methodology to a large set of experiments.
IMHO, this is a pleasing example of the kind of serendipitous collaboration that can arise when we are willing to have an open mind and look for possible applications to our techniques in other fields. Kudos to Ludovico, Mattia and their co-authors for going all the way and for publishing their article in a coveted outlet. I look forward to seeing more examples of cross fertilization within CS@GSSI.
Addendum 26/9/2018: Ludovico and Mattia kindly sent me two photos they took while the work was ongoing. (The all-important coffee machine is not pictured.)

Some recent achievements by the PhD students in CS at the GSSI
Like many others, I believe that students are amongst the best ambassadors for an academic institution, and that their achievements are a good indication of the quality of a graduate programme and of the mentoring skills of its associated faculty members. Therefore, it has given me great pleasure to witness the accolades received by some of the (former) students in the doctoral programme in computer science at the Gran Sasso Science Institute over the last few months.
Readers of this blog might recall that I wrote posts on the following two items.
Readers of this blog might recall that I wrote posts on the following two items.
- GSSI alumna Yllka Velaj, now at CWI, was a co-recipient of the 2018 Women@McKinsey Dissertation Award.
- Emilio Cruciani (GSSI, Italy) and Roberto Verdecchia (GSSI, Italy, and Vrije Universiteit Amsterdam, NL) were two of the authors of a research paper presented at ICSE 2018, the 40th International Conference on Software Engineering. ICSE is the flagship conference in Software Engineering and is very selective its technical-research-paper track is the most prestigious one within the conference. Emilio and Roberto were first-year CS students at the time.
- GSSI alumni Alkida Balliu and Dennis Olivetti, now postdocs at Aalto University in Jukka Suomela's group, co-authored a paper presented at STOC 2018. The work on the paper was done while they were at the GSSI.
- Third-year GSSI student Ahmed Abdelsalam was part of the netgroup team at CNIT/uniroma2 that won the Interworking stream at the SoftFIRE Challenge, which addresses issues related to interoperability of the current platform with other infrastructures. In particular, Ahmed's work on IPv6 Segment Routing (SRv6) and his recently developed SRv6 aware version of the network intrusion and detection system Snort featured in the award-winning proposal. If you use Linux, you are probably already running Ahmed's software!
- In May 2018, Roberto Verdecchia received three awards for his research:
- a bronze medal at the Research Student Competition of the Internationa
l Conference on Mobile Software Engineering and Systems, - Runner-Up Best Paper Award at ICT4S for the study “Empirical Evaluation of the Energy Impact of Refactoring Code Smells” and, last but by no means least,
- the best early career researcher award at the International Conference on Software Architectures (ICSA).

ICE-TCS Theory Day(s) 2018
The Icelandic Centre of Excellence in Theoretical Computer Science held its 14th annual Theory Day today. The programme is here.
Takeshi Tokuyama (Tohoku University, Japan) kicked off the day with a talk entitled Deformation of Determinants and Related Combinatorics. The talk was based on work that Takeshi did in 1986 (as a mathematics postdoc) and published in 1988. He referred to it as his "sleeping beauty" as there has been a peak of interest in that paper only in the last ten years. Takeshi's "Weyl character formula" was even the subject of a PROMYS research project in the summer of 2013, which led to a paper that generalizes that formula to the Hall-Littlewood polynomials. The talk surveyed many interesting topics and connections with alternating sign matrices, computation of Boltzmann weights, and crystal bases.
The second half of the Theory Day 2018 was devoted to three short presentations by ICE-TCS researchers devoted to research highlights from the centre. Antonis Achilleos set himself the goal of presenting two and a half years worth of research on monitorability, carried out within the framework of the TheoFoMon project, in 15 minutes. Tigran Tonoyan presented joint work with former ICE-TCS postdoc Christian Konrad addressing the question of whether randomness helps in guessing the middle point of an on-line sequence. (Answer: It does.) Last, but not least, Christian Bean gave an overview of an ongoing project whose goal is to automate proofs of results in enumerative combinatorics. Christian presented many examples of published theorems, some of which from 2018, that can be established using their CombSpecSearcher algorithm and that were previously obtained using human ingenuity.
The Theory Day was preceded by a seminar by Tami Tamir (Efi Arazi School of Computer Science, The Interdisciplinary Center) on Thursday, 23 August 2018. In her talk, Tami gave an excellent introduction to the main research questions in algorithmic game theory, introduced network formation games and discussed her work with Guy Avni and Orna Kupferman on automata formation games, where the goal of each player is given by a regular language rather than by simple reachability objectives. Tami focused on results presented in this paper, which were mostly of a negative nature. She concluded her informative and entertaining presentation by introducing her university, the Efi Arazi School of Computer Science and how they try to tackle the gender issues in computer science.
Overall, this was another good edition of the Theory Day at ICE-TCS. When we founded the centre on the 29th of April 2005, I had no idea that it would see so many installments of this event. I feel fortunate to have taken part in organizing them, to have worked with so many great colleagues in Iceland and to have met many very interesting and inspiring people along the way. Stay tuned for the Theory Day 2019, which will most likely be held in the spring of next year.

Citing the explanation of her work given by Yllka in the CWI press release:
"Understanding the dynamics that regulate the diffusion of information in complex networks has been one of the main goals in the field of complex network analysis. The problem, which is also known as influence spreading or information diffusion problem, is motivated by many applications in different fields: from marketing to epidemiology, going through the study of adoption of innovations and the analysis of social networks. In my PhD thesis, I designed new efficient algorithms which use a given budget to suggest new links to be added to the network in order to maximize the diffusion of information”.

Most Influential POPL Paper Award 2018: "Multiparty asynchronous session types" by Kohei Honda, Nobuko Yoshida and Marco Carbone
I heard the great news that the paper Multiparty asynchronous session types by the late Kohei Honda,
Nobuko Yoshida and Marco Carbone has received the Most Influential POPL
Paper Award 2018. See
This
award is given annually to the author(s) of a paper presented at the
Symposium on Principles of Programming Languages (POPL) held 10 years prior to the award year. The papers are judged by their influence over the past decade.
The citation for the award is available from the above-mentioned web page, but I repeat it here for ease of reference:
Session types are a type-based framework for codifying
communication structures and verifying protocols in concurrent,
message-passing programs. Previously, session types could only
model binary (two-party) protocols. This paper generalizes the
theory to the multiparty case with asynchronous communications,
preventing deadlock and communication errors in more sophisticated
communication protocols involving any number (two or more) of
participants. The central idea was to introduce global types,
which describe multiparty conversations from a global perspective
and provide a means to check protocol compliance. This work has
inspired numerous authors to build on its pioneering foundations
in the session types community and has initiated many applications
of multiparty session types in programming languages and tools. It
has also influenced other areas of research, such as software
contracts, runtime verification and hardware specifications.
Congratulations to the authors of the paper and to the concurrency community at large, whose work over the last ten years contributed to this award and, most importantly, to significant scientific advances that are now embodied in programming languages and tools that are already having practical impact (see the work with Cognizant, Red Hat, and VMWare on Scribble, and with the OOI), and that I believe will find increasing application in years to come.

Contributions to Logic and Computation. I encourage all members of the community to nominate their favourite paper or small group of papers in logic and computation published within the past 25 years.
The 2018 Alonzo Church Award for Outstanding Contributions to Logic and Computation
Call for Nominations
Introduction
An annual award, called the Alonzo Church Award for Outstanding Contributions to Logic and Computation, was established in 2015 by the ACM Special Interest Group for Logic and Computation (SIGLOG), the European Association for Theoretical Computer Science (EATCS), the European Association for Computer Science Logic (EACSL), and the Kurt Gödel Society (KGS). The award is for an outstanding contribution represented by a paper or by a small group of papers published within the past 25 years. This time span allows the lasting impact and depth of the contribution to have been established. The award can be given to an individual, or to a group of individuals who have collaborated on the research. For the rules governing this award, see: http://siglog.org/awards/ alonzo-church-award/.
The 2017 Alonzo Church Award was given jointly to Samson Abramsky, Radha Jagadeesan, Pasquale Malacaria, Martin Hyland, Luke Ong, and Hanno Nickau for providing a fully-abstract semantics for higher-order computation through the introduction of game models, see: http://siglog.org/ winners-of-the-2017-alonzo- church-award/.
Eligibility and Nominations
The contribution must have appeared in a paper or papers published within the past 25 years. Thus, for the 2018 award, the cut-off date is January 1, 1993. When a paper has appeared in a conference and then in a journal, the date of the journal publication will determine the cut-off date. In addition, the contribution must not yet have received recognition via a major award, such as the Turing Award, the Kanellakis Award, or the Gödel Prize. (The nominee(s) may have received such awards for other contributions.) While the contribution can consist of conference or journal papers, journal papers will be given a preference.
Nominations for the 2018 award are now being solicited. The nominating letter must summarise the contribution and make the case that it is fundamental and outstanding. The nominating letter can have multiple co-signers. Self-nominations are excluded. Nominations must include: a proposed citation (up to 25 words); a succinct (100-250 words) description of the contribution; and a detailed statement (not exceeding four pages) to justify the nomination. Nominations may also be accompanied by supporting letters and other evidence of worthiness.
Nominations should be submitted to catuscia@lix.polytechnique.fr by March 1, 2018.
Presentation of the Award
The 2018 award will be presented at ICALP 2018, the International Colloquium on Automata, Languages and Programming. The award will be accompanied by an invited lecture by the award winner, or by one of the award winners. The awardee(s) will receive a certificate and a cash prize of USD 2,000. If there are multiple awardees, this amount will be shared.
Award Committee
The 2018 Alonzo Church Award Committee consists of the following five members: Thomas Eiter, Javier Esparza, Catuscia Palamidessi (chair), Gordon Plotkin, and Natarajan Shankar.

First-year computer science students at the GSSI publish paper at ICSE 2018
The paper "FAST Approaches to Scalable Similarity-based Test Case
Prioritization" by Breno Miranda (UFPE, Brazil), Emilio Cruciani (GSSI, Italy), Roberto Verdecchia
(GSSI, Italy, and Vrije Universiteit Amsterdam, NL) and Antonia Bertolino (ISTI - CNR, Italy) has been accepted as a technical research paper at ICSE 2018, the 40th International Conference on Software Engineering. ICSE is the flagship conference in Software Engineering and is very selective its technical-research-paper track is the most prestigious one within the conference.
The paper contributes to the classic area of software testing, which is one of the approaches developed by computer scientists to increase their confidence that computing systems actually do what they were designed to achieve. Since the number of tests that can be performed on a computing system is enormous, test-case prioritization is a crucial element in any practical testing framework. In that approach, one prioritizes test cases so that they can detect faults more efficiently using the available limited resources.
The paper to be presented at ICSE 2018 is the first that applies techniques from data mining to test case prioritization. In particular, it shows that the use of ideas from locality-sensitive hashing, a technique stemming from research in TCS that has been employed to great effect in approximate similarity searches in audio and video data, amongst others, leads to effective test prioritization in practice, when one needs to select tests effectively amongst millions of possible ones.
Antonia Bertolino is a member of the Scientific Board for the PhD programme in Computer Science at the GSSI. Breno Miranda is currently a postdoctoral researcher in Brazil and is one of Antonia Bertolino's former PhD students. Emilio Cruciani and Roberto Verdecchia just started their second year as PhD students in computer science at the GSSI and the paper to be presented at ICSE 2018 builds on their project for the first-year Software Testing course held in early 2017 at the GSSI by Antonia Bertolino. The project itself arose from a question asked by the students during the lectures. This is what inspiring, research-based teaching can produce when there is intellectual chemistry between lecturers and students.

A letter to Franklin Foer (guest post by Frits Vaandrager)
Frits Vaandrager has sent the appended letter, which I am posting with his kind permission, to the journalist Franklin Foer. (The letter is also available here.)
Frits wrote to me saying that:
Frits wrote to me saying that:
Franklin Foer published an interesting book, World without Mind, that was named a "Notable book of 2017" by the New York Times. According to Foer, computer scientist started to use the term "algorithm" because of "status anxiety", as a form of name dropping by programmers to suggest that they were also serious scientists. In my letter to Foer I give some historic evidence that this framing is utterly incorrect, but I'd be interested in the views of colleagues from the TCS community on this matter.Please share your views on this matter as comments to this post. It is important to put the record straight and I am glad that Frits took the time to write a cogent letter to Mr. Foer. Thank you!
Dear Mr Foer,
With much interest I have read your book “World without mind”.
I agree with many of your conclusions! But as a computer scientist
who has been working on algorithms for more than 30 years, I am also
deeply troubled by one paragraph in your book:
“For the first decades of computing, the term
“algorithm” wasn’t much mentioned. But as computer science departments
began sprouting across campuses in the 60s, the term acquired a new
cachet. Its vogue was the product of status anxiety. Programmers,
especially in the academy, were anxious to show that they weren’t mere
technicians. They began to describe their work as algorithmic, in part
because it tied them to one of the greatest of all mathematicians – the
Persian polymath Muhammad ibn Musa al-Khwarizmi, or as he was known in
Latin, Algoritmi. During the 12th century, translations of al-Khwarizmi
introduced Arabic numerals to the west; his treatises pioneered algebra
and trigonometry. By describing the algorithm as the fundamental element
of programming, the computer scientists were attaching themselves to a
grand history. It was a savvy piece of name-dropping: See, we’re not
arriviste, we’re working with abstractions and theories, just like the
mathematicians!”
Do you have historic sources for these strong statements?
Much of computer science is rooted in the work of
mathematicians and logicians such as Turing, Church and von Neumann.
These researchers used the word “algorithm” already before computers
were built, see for instance p349 of Alonzo Church’s 1936 paper “An unsolvable problem of elementary number theory”.
Together with Turing’s 1936 paper “On computable numbers, with an
application to the entscheidungsproblem”, this paper forms the basis for
the so-called Church-Turing thesis, which in turn laid the foundation
of theoretical computer science. The computer science pioneers
definitely knew the term “algorithm”!!
The term “algorithm” was maybe not used so often by
computer scientists during the initial years (often they used terms such
as “effective procedure” or “computable function”), but that certainly
changed in 1958 with the influential work on ALGOL (short for
Algorithmic Language), a family of imperative computer programming
languages. The researchers who worked on Algol e.g. Bauer, Backus,
Dijkstra, Perlis, Naur, van Wijngaarden & McCarthy were established
scientists who definitely did not suffer from “status anxiety”. Backus,
Dijkstra, Perlis, Naur and McCarthy later received the Turing award, the major prize for computer science research, for their groundbreaking research.
In order to appreciate the wonderful scientific work on algorithms, I can recommend you, for instance, to read the book Algorithmics – The spirit of computing
by David Harel. I hope that, after studying this book, you will be also
convinced that the fact that programmers used the term algorithm is not
a form of name dropping. The work on algorithms since the advent of
computers very much fits into the tradition of the work started by great
scientists like Euclides and al-Khwarizmi.
Scientific knowledge may always be used for both good
and bad things. Like you, I am very concerned about the use of
algorithms by Google, Facebook, Apple and Amazon. But I disagree with
any suggestion that there is no science behind computer science
algorithms!
Looking forward to your reaction, with best regards,
Frits Vaandrager
