L'IRIF est une unité mixte de recherche (UMR 8243) entre le CNRS et l'Université Paris-Diderot, qui héberge deux équipes-projets INRIA.

Les objectifs scientifiques de l'IRIF se situent au cœur de l'informatique, et plus particulièrement sur la conception, l'analyse, la preuve et la vérification d'algorithmes, de programmes et de langages de programmation. Ils s'appuient sur des recherches fondamentales développées à l'IRIF en combinatoire, graphes, logique, automates, types, sémantique et algèbre.

L'IRIF regroupe près de deux cents personnes. Six de ses membres ont été lauréats de l'European Research Council (ERC), et trois sont membres de l'Institut Universitaire de France (IUF).

FOCS

09.08.2018
IRIF organizes the 59th IEEE Symposium on Foundations of Computer Science (FOCS 2018) on October 7-9, 2018. FOCS is a leading annual conference in Theoretical Computer Science, and has served in the last 60 years as a venue for announcing the major scientific advances in the field. The list of accepted papers is now available, and the registration is now open (deadline for early rate: September 9, 2018).

FOCS

09.08.2018
IRIF organizes the 7th FILOFOCS (French-Israeli Laboratory on Foundations of Computer Science) workshop which will be held at the institut Henri Poincaré (IHP), on 3-5 October, 2018. A preliminary list of speakers in now available and registration (mandatory, but free) is now open.

Michel Habib

01.08.2018
At the occasion of the retirement of Michel Habib and in celebration of his achievements, IRIF organizes a two-day conference “40 années d'algorithmique de graphes”, 11-12 Oct, Amphi Turing (Sophie Germain, Univ. Paris Diderot). Free mandatory registration.

FLOC'18

10.07.2018
Mihaela Sighireanu (IRIF) is organizing the second edition of SL-COMP, a competition of solvers for separation logic. The final results will be presented at ADSL 2018, a workshop of FLOC2018, which will take place in Oxford on the 13.07.18.
separation logic

Separation logic is a language for describing properties and reasoning about programs that use mutable data structures (i.e. memory cells and pointers). Separation logic has a special support for local reasoning, which is the ability to use and compose properties that involve a subset of the data configuration only: it separates the relevant portion of the data structure from the irrelevant one. Local reasoning gives more compact proofs and specifications for imperative programs than with prior formalisms. Furthermore, it helps with the scalability of proofs done in automatic and semi-automatic verification and program analysis tools.
Avocs'18

06.07.2018
Mihaela Sighireanu (IRIF) is co-chair of the 18th International Workshop on Automated Verification of Critical Systems (AVOCS) which will take place in Oxford from 18.07.18 to 19.07.18 as part of FLOC2018.

LICS

29.06.2018
Raphaëlle Crubillé (PhD student IRIF) will present at LICS 2018 an analytic account of the discrete probabilities fragment of a denotational model for higher-order programming with general probabilities, hopefully a first step towards proving that this model is fully abstract.
fully abstract

The quest for a fully abstract model for the contextual equivalence of PCF, a paradigmatic functional language, has been influential in the area of programming languages semantics. A model is fully abstract if it is both sound and complete. A denotational model is complete for a given notion of equivalence between programs if equivalent programs have the same denotation, some mathematical object they are mapped to; it is sound if programs having the same denotation are equivalent.
CIJM

27.06.2018
Berenice Delcroix-Oger (IRIF) participated to the annual festival "Salon Culture & Jeux Mathématiques 2018". On the following video (1:50), she presents a funny game where mathematics help you perform magic tricks!

Amina Doumane

15.06.2018
Amina Doumane (former PhD student at IRIF, now at LIP) was awarded the Ackermann prize of EACSL for her PhD thesis entitled On the infinitary proof theory of logics with fixed points.

TYPES 06.06.2018
Delia Kesner (IRIF) and Matthieu Sozeau (IRIF) will both give invited talks entitled “Multi Types for Higher-Order languages” and “The Predicative, Polymorphic Calculus of Cumulative Inductive Constructions and its implementation” at TYPES 2018, held in Braga (Portugal), June 18-21.

IRIF distinguished talk 06.06.2018
We are delighted to host as part of our IRIF Distinguished Talks Series Christos Papadimitriou (Columbia University) on July 13, 10:30 for a talk entitled “A computer scientist thinks about the Brain”.
