Two papers by GSSI researchers at AAAI 2019

The main track of AAAI 2019 will feature the presentation of two papers by CS@GSSI researchers. The two papers are
The paper by Gianlorenzo, Martin and Lorenzo (who is a CS@GSSI alumnus)  contributes to the study of one of the main tools in the analysis of social networks, viz. centrality metrics. Since central nodes are very influential in their network, increasing the centrality of a network user is a widely studies optimization problem in network analysis. Gianlorenzo, Martin and Lorenzo have studied the centrality maximization problem in undirected networks for one of the most important shortest-path-based centrality measures, namely the coverage centrality. They give several hardness results, approximation algorithms and an experimental study of their effectiveness.

The paper by Emilio, Emanuele and Giacomo analyzes the behaviour of a simple majority-based dynamics on a class of networks that present a clustered structure. By combining symmetry-breaking techniques and concentration of probability arguments with a linear algebraic approach, it provides the first symmetry-breaking analysis of dynamics for non-consensus problems on non-complete topologies. The analysis shows that, when the agents of the networks randomly initialize their states, the 2-Choices dynamics makes the network quickly converge to a configuration where the agents have a state that identifies the cluster to which  they belong. The 2-Choices dynamics can be seen as a simple distributed Label Propagation Algorithm (a widely used class of heuristics for graph clustering) with quasi-linear message complexity. In this setting, the paper represents the first rigorous theoretical result. Moreover, in the context of evolutionary biology, it gives a proof of principle of sympatric/parapatric speciation, in which there is no complete geographical isolation between the species: No simple dynamics was proposed before to explain such a fundamental phenomenon.

Congratulations to Emilio, Gianlorenzo and their coauthors! It is always a pleasure to see young researchers in one's group succeed and develop their careers. Emilio Cruciani is a beginning third-year student who already has an impressive track record of high-quality publications. Keep him in mind for postdoctoral and tenure-track positions, once he finishes his studies!

The AAAI conference promotes research in artificial intelligence and is one of the premier conferences in AI, where researchers, practitioners, and scientists meet to present and discuss most recent trends and results in the field of artificial intelligence. This year it received a record number of over than 7,700 submissions of which 1,150 were accepted (with an acceptance rate of 16.2%). The list of accepted papers is at https://aaai.org/…/uplo…/2018/11/AAAI-19_Accepted_Papers.pdf.

Call for nominations for the Presburger Award 2019

Anca Muscholl asked me to advertise the call for nominations for the Presburger Award. I hope that members of the TCS community will nominate many of the young scientists (see the text below for the definition of "young") doing exciting work in TCS.  I wish Anca, Jukka and Thore good luck with their work, as I am sure they will be faced with some difficult choices.

Starting in 2010, the European Association for Theoretical Computer Science
(EATCS) established the Presburger Award. The Award is conferred annually at
the International Colloquium on Automata, Languages and Programming (ICALP) to a young scientist (in exceptional cases to several young scientists) for outstanding contributions in theoretical computer science, documented by a published paper or a series of published papers.

The Award is named after Mojżesz Presburger who accomplished his path-
breaking work on decidability of the theory of addition (which today is called
Presburger arithmetic) as a student in 1929.

Nominations for the Presburger Award can be submitted by any member or
group of members of the theoretical computer science community except the nominee and his/her advisors for the master thesis and the doctoral dissertation. Nominated scientists have to be at most 35 years at the time of the deadline of nomination (i.e., for the Presburger Award of 2019 the date of birth should be in 1983 or later). The Presburger Award Committee of 2019 consists of Thore Husfield (Lund University and IT University of Copenhagen), Anca Muscholl (LaBRI) and Jukka Suomela (Aalto, chair). Nominations, consisting of a two page justification and (links to) the respective papers, as well as additional supporting letters, should be sent by e-mail to:

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.
However, there were several other events worth reporting on which I was too lazy to write a few lines on this blog. Here are three more examples.
  • 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: 
I'm sure that this is just a small sample and that CS@GSSI students have more achievements of which I am not aware. It is a humbling experience to  see how smart many young researchers are. All one can hope for is to provide a good example for them and to play a small, positive role in their development as scientists.

Best PhD thesis award of the Italian Chapter of the EATCS

One of the prizes of the Italian Chapter of the EATCS is the Best Italian PhD Thesis in Theoretical Computer Science Award. This year, the committee (consisting of Vincenzo Auletta,  Ferdinando Cicalese and Carla Piazza) has unanimously decided to bestow the award on the following two young scientists:
  • Michele Ciampi for his thesis "Round and Computational Efficiency of Two-Party Protocols" and 
  • Luisa Siniscalchi for her dissertation "Delayed-Input and Non-Malleable Cryptographic Protocols".
Both the award recipients were PhD students at the University of Salerno working with Giuseppe Persiano and Ivan Visconti, which is remarkable.

Moreover, the award committee found that the following two theses deserved a honourable mention:
Congratulations to these young scientists. I wish them all a great career, whatever they decide to do in the future.

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.

2018 Women@McKinsey Dissertation Award to GSSI alumna Yllka Velaj

GSSI alumna Yllka Velaj has been selected as co-recipient of the 2018 Women@McKinsey Dissertation Award (https://www.mckinsey.it/womenmckinsey-dissertation-award), which is given to a female researcher for a master or doctoral thesis on themes related to Advanced Data Analytics or Machine Learning. Yllka receives the award for her PhD thesis "Information spreading with network augmentation" that she completed at the GSSI under the supervision of Pierluigi Crescenzi (University of Florence) and Gianlorenzo D'Angelo (GSSI). The award comes with a job offer by McKinsey & Company, and with financial support to attend the Open Data Science Conference 2018, which will be held in London in the period 19-22 September 2018.

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”.

Yllka is an Italian scientist of Albanian origin. She obtained her BSc in Computer Science and her MSc in Distributed Systems and Computer Networks from the University of L'Aquila. She was a PhD student in Computer Science in the joint PhD GSSI-IMT programme at the Gran Sasso Science Institute. After one year as a postdoctoral researcher at the University of Chieti-Pescara, in May 2018 she joined the Networks & Optimization group at CWI in Amsterdam as a winner of the fellowship programme promoted by ERCIM - the European Research Consortium for Informatics and Mathematics.

Yllka's research interests include combinatorial algorithms, network analysis, algorithm engineering and recently also algorithmic game theory.

Congratulations to Yllka, her supervisors and the CS group at the GSSI as a whole.

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.

Call for nominations for the 2018 Alonzo Church Award

Catuscia Palamidessi asked me to post the call for nominations for this year's Alonzo Church Award for Outstanding 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.
