New publication: VECoS'18
by Renault Etienne 14 Jun '18

14 Jun '18

Greetings, We are pleased to announce that the following paper has been accepted in the 12th International Conference on Verification and Evaluation of Computer and Communication Systems (VECoS'18). Please find the title and abstract below. Title and corresponding authors: "Improving Parallel State-Space Exploration Using Genetic Algorithms" Etienne Renault (1) (1) LRDE, Epita, Paris, France Abstract: The verification of temporal properties against a given system may require the exploration of its full state space. In explicit model-checking this exploration uses a Depth-First-Search (DFS) and can be achieved with multiple randomized threads to increase performance. Nonetheless the topology of the state-space and the exploration order can cap the speedup up to a certain number of threads. This paper proposes a new technique that aims to tackle this limitation by generating artificial initial states, using genetic algorithms. Threads are then launched from these states and thus explore different parts of the state space. Our prototype implementation runs 10% faster than state-of-the-art algorithms. These results demonstrate that this novel approach worth to be considered as a way to overcome existing limitations.

Accepted paper at SYNT 2018
by Colange Maximilien 07 Jun '18

07 Jun '18

Greetings, We are pleased to announce that the following article has been accepted for publication in the 7th Workshop on Synthesis (SYNT@CAV 2018), to be held in Oxford on July, 18th 2018. "Reactive Synthesis from LTL Specification with Spot" Thibaud Michaud (LRDE -- EPITA) Maximilien Colange (LRDE -- EPITA) Abstract: We present ltlsynt, a new tool for reactive synthesis from LTL specifications. It relies on the efficiency of Spot to translate the input LTL specification to a deterministic parity automaton. The latter yields a parity game, which we solve with Zielonka's recursive algorithm. The approach taken in ltlsynt was widely believed to be impractical, due to the double-exponential size of the parity game, and to the open status of the complexity of parity games resolution. ltlsynt ranked second of its track in the 2017 edition of the SYNTCOMP competition. This demonstrates the practical applicability of the parity game approach, when backed by efficient manipulations of omega-automata such as the ones provided by Spot. We present our approach and report on our experimental evaluation of ltlsynt to better understand its strengths and weaknesses. -- Maximilien Colange Assistant Professor LRDE -- EPITA (+33) 1 53 14 59 45

Indeed, they allow a modeling of image contents at different (and complementary) levels of scales, resolutions and semantics. Methods based on such image representations have been able to tackle various complex challenges such as multi-scale image segmentation, image filtering, object detection, recognition, and more recently image characterization and understanding. In this talk, we will focus on the binary partition tree (BPT), which is a well-known hierarchical data-structure, frequently involved in the design of image segmentation strategies. In a first part, we will focus on the construction of such trees by providing a generalization of the BPT construction framework to allow one to embed multiple features, which enables handling many metrics and/or many images. In a second part, we will discuss how it may be possible to evaluate the quality of such a structure and its ability to reconstruct regions of the image corresponding to segments of reference given by a user. Finally, we will see some examples of image analysis and recognition processes involving these hierarchical structures. The main thematic application is remote sensing and satellite image analysis. -- Camille Kurtz obtained the MSc and PhD from Université de Strasbourg, France, in 2009 and 2012. He was a post-doctoral fellow at Stanford University, CA, USA, between 2012 and 2013. He is now an Associate Professor at Université Paris Descartes, France. His scientific interests include image analysis, data mining, medical imaging and remote sensing. L'entrée du séminaire est libre.

For a program variable, the algorithm produces an expression representing the variable value after the number of cycle iterations specified by parameters of the expression. The algorithm is partial in the sense that it can fail to find such an expression for some program variables (for example, it fails in cases where the variable value depends on the order of paths in the cycle taken during iterations). We present two applications of this loop summarization procedure. The first is the construction of a nontrivial necessary condition on program input to reach a given program location. The second application is a loop bound detection algorithm, which produces tighter loop bounds than other approaches. -- Jan Strejcek is an associate professor at the Faculty of Informatics of Masaryk University located in Brno, Czech Republic. He received his PhD in Computer Science (2005) and Master degrees in Mathematics (2000) and Computer Science (2001) from the same university. His current research focuses on automata over infinite words, automatic program analysis, and SMT-solving of quantified bitvector formulae. L'entrée du séminaire est libre.

One of the most serious problems with model checking in practice is the so-called "state explosion problem", i.e the state-space of a system can be too large to be processed in a reasonable time and to be stored on the memory. This problem can be addressed using symbolic or explicit techniques. In this talk I will focus on the latter one by overviewing the recent advances in (1) emptiness checks and (2) partial-order reductions. 15h00-15h30: Mathias Ramparison (LIPN, Université Paris 13), "Timed automata with parametric updates" Abstract: Timed automata (TAs) represent a powerful formalism to model and verify systems where concurrency is intricated with hard timing constraints. However, they can seem limited when dealing with uncertain or unknown timing constants. Several parametric extensions were proposed in the literature, and the vast majority of them leads to the undecidability of the EF-emptiness problem: "is the set of valuations reaching a given location empty?" Here, we study an extension of TAs where clocks can be updated to a parameter. While the EF-emptiness problem is undecidable for rational-valued parameters, it becomes PSPACE-complete for integer-valued parameters. In addition, exact synthesis of the parameter valuations set can be achieved. We also extend these two results to the EF-universality ("are all valuations reaching a given location?"), AF-emptiness ("is the set of valuations such that a given location is unavoidable empty?") and AF-universality ("are all valuations such that a given location is unavoidable?") problems. 15h30-16h00: pause café 16h00-16h30: vie du groupe 15h30-16h00: pause café 16h00-16h30: vie du groupe ======================================================================== -- Alexandre Duret-Lutz

[COP 2018] CFP: 10th Workshop on Context-Oriented Programming (COP'18)
by Didier Verna 24 Apr '18

24 Apr '18

Call for Papers *** COP 2018: 10th International Workshop on Context-Oriented Programming *** July 16th, 2018 Co-located with ECOOP/ISSTA 2018 in Amsterdam, Netherlands === Advanced Modularity for Run-time Composition === Contextual information is playing an ever-increasing role in our information-centric world. Current-day software systems need to adapt continuously to changing execution and usage contexts, even while they are running. Unfortunately, mainstream programming languages and development environments still do not support this level of dynamic adaptivity very well, leading developers to implement complex designs to anticipate various dimensions of variability. Context-Oriented Programming directly supports variability at the programming level, featuring dedicated programming abstractions enabling programmers to write software applications that adapt dynamically to a wide range of dynamic attributes. It enables run-time behaviour to be dispatched directly on any detected properties of the execution or user context. Since more than a decade, several researchers have been working on a variety of notions approaching that idea. Implementations ranging from first prototypes to mature platform extensions used in commercial deployments have illustrated how multidimensional dispatch can be supported effectively to achieve expressive run-time variation in behavior. Our series of International Workshops on Context-Oriented Programming (COP) at ECOOP since 2009 have shown to be well-received, each attracting around 30 participants. Also in 2018 we hope to advance this vibrant research domain at ECOOP in the beautiful and lively city of Amsterdam. === Topics === Topics of interest to the workshop include, but are not limited to: - Interesting application domains and scenarios for COP - Programming language abstractions for COP (e.g. dynamic scoping, roles, traits, prototype-based extensions) - Implementation techniques and mechanisms for COP (e.g. different kinds of dynamic, contextual, and multi-dimensional dispatch or pre-dispatch) - Implementation issues for COP such as optimization, VM support, JIT compilation etc. - Implemented use-cases, case studies, or prototypes of COP - Theoretical foundations for COP (e.g., semantics, type systems) - Configuration languages (e.g. feature description interpreters, transformational approaches) - Interaction between non-functional programming concerns and COP (e.g. security, persistence, concurrency, distribution) - Modularization approaches for COP (e.g. modules, aspects, features, layers, plugins) - Guidelines to apply COP (e.g. best practices, idioms, patterns) - Run-time support for COP (e.g. reflection, dynamic binding) - Tool support (e.g. design tools, IDEs, debuggers) - Support for COP at the modeling level - Beyond context-oriented behavior adaptation (e.g., UI adaptation, DB adaptation). === Submission guidelines === COP invites submissions of high-quality papers reporting original research, or describing innovative contributions to, or experience with context-oriented programming, its implementation, and application. Papers that depart significantly from established ideas and practices are particularly welcome. Submissions must not have been published previously and must not be under review for any other refereed event or publication. The program committee will evaluate each contributed paper based on its relevance, significance, clarity, and originality. Papers are to be submitted via EasyChair (https://easychair.org/conferences/?conf=cop2018) They must be written in English, provided as PDF documents, and follow the new ACM Master Article Template with the sigconf option (https://www.acm.org/publications/proceedings-template) They should not exceed 8 pages. Accepted papers will be published in the ACM Digital Library. === Important dates === Submission deadline: May 18th, 2018 (AoE) Notifications: June 8th, 2018 Final version: June 29th, 2018 === Program committee === Tomoyuki Aotani, Tokyo Institute of Technology, Japan Nicolás Cardozo, Universidad de los Andes, Colombia Coen De Roover, Vrije Universiteit Brussel, Belgium Elisa Gonzalez Boix, Vrije Universiteit Brussel, Belgium David H.

New journal publication: Lisp, Jazz, Aikido
by Didier Verna 12 Apr '18

12 Apr '18

Hello, I'm happy to announce the upcoming publication of my essay entitled Lisp, Jazz, Aikido, to appear in Volume 2 Issue 3 of the Art, Science and Engineering of Programming journal, in April 2018. The abstract is given below. The relation between Science (what we can explain) and Art (what we can't) has long been acknowledged and while every science contains an artistic part, every art form also needs a bit of science. Among all scientific disciplines, programming holds a special place for two reasons. First, the artistic part is not only undeniable but also essential. Second, and much like in a purely artistic discipline, the act of programming is driven partly by the notion of aesthetics: the pleasure we have in creating beautiful things. Eventhough the importance of aesthetics in the act of programming is now unquestioned, not much has been written on the subject. The field called "psychology of programming" focuses on the cognitive aspects of the activity, with the goal of improving the productivity of the programmers. Very few programmers have written about their thought process while programming either, and even fewer on their concern for aesthetics, and the impact it has on their activity. I can see three reasons for this. First, it may be frightening to do so. Reflecting on our aesthetic sensitivities involves thinking about our own emotions, and not everyone is ready or willing to perform that kind of introspection. Second, this introspection needs to be very deep, as our aesthetic sensitivities are extremely personal. Third, this introspection also needs to be very broad, as our aesthetic sensitivities affect every part of our lives. The purpose of this essay is to shed some new light on the art of programming by answering questions such as what makes us like or dislike such or such language or paradigm, or why do we shape our programs the way we do, all of this from the angle of aesthetics. Starting from the assumption that aesthetics is an inherently transversal concern, it should be possible for every programmer to find the same aesthetic driving force in every creative activity they undertake, not just programming, and in doing so, get deeper insight on why and how they do things the way they do. On the other hand, because our aesthetic sensitivities are so personal, all we can really do is relate our own experiences and share it with others, in the hope that it will inspire them to do the same. It is certainly an important purpose of this essay. My personal life has been revolving around three major creative activities, of equal importance: programming in Lisp, playing Jazz music and practicing Aikido. But why so many of them, why so different ones, and why these specifically? By introspecting my personal aesthetic sensitivities, I eventually realized that my tastes in the scientific, artistic and physical domains are all motivated by the same driving forces, hence unifying Lisp, Jazz and Aikido as three expressions of a single essence, not so different after all. In doing so, I gained considerable insight on my own psychology of programming, perhaps common to most lispers, perhaps also common to other programming communities. But that is for the reader to decide... -- Resistance is futile. You will be jazzimilated. Lisp, Jazz, Aïkido: http://www.didierverna.info

Chapter published in Handbook of Parallel Constraint Reasoning
by Renault Etienne 10 Apr '18

10 Apr '18

Greetings, We are pleased to announce that the following chapter has been published in Handbook of Parallel Constraint Reasoning (Springer). Please find the title and abstract below. Title and corresponding authors: "Parallel Model Checking Algorithms for Linear-Time Temporal Logic" Jiri Barnat (1), Vincent Bloemen (2), Alexandre Duret-Lutz (3), Alfons Laarman (4), Laure Petrucci(5), Jaco van de Pol (2), and Etienne Renault (3) (1) Masaryk University, Brno, Czech Republic (2) University of Twente, Enschede, The Netherlands (3) LRDE, Epita, Paris, France (4) Leiden University, Leiden, The Netherlands (5) LIPN, CNRS, Paris, France Abstract: Model checking is a fully automated, formal method for demonstrating absence of bugs in reactive systems. Herebugs are violations of properties in Linear-time Temporal Logic (LTL). A fundamental challenge to its application is the exponential explosion in the number of system states. The current chapter discusses the use of parallelism in order to overcome this challenge. We reiterate the textbook automata-theoretic approach, which reduces the model checking problem to the graph problem of finding cycles. We discuss several parallel algorithms that attack this problem in various ways, each with different characteristics: Depth-first search (DFS) based algorithms rely on heuristics for good parallelization, but exhibit a low complexity and good on-the-fly behavior. Breadth-first search (BFS) based approaches, on the other hand, offer good parallel scalability and support distributed parallelism. In addition, we present various simpler model checking tasks, which still solve a large and important subset of the LTL model checking problem, and show how these can be exploited to yield more efficient algorithms. In particular, we provide simplified DFS-based search algorithms and show that the BFS-based algorithms exhibit optimal runtimes in certain cases.
