IRIF, the Research Institute on the Foundations of Computer Science, is a research laboratory of CNRS and Université Paris-Diderot, also hosting two INRIA project-teams.

The scientific objectives of IRIF are at the core of computer science and, in particular, they focus on the conception, analysis, proof, and verification of algorithms, programs, and programming languages. They are built upon fundamental research activities developed at IRIF on combinatorics, graphs, logics, automata, type, semantics, and algebras.

IRIF hosts about 200 people. Six of its members have been distinguished by the European Research Council (ERC), three are members of the Institut Universitaire de France (IUF), and two are members of the Academia Europaea.

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”.

Software Heritage

06.06.2018
Today Roberto Di Cosmo (professor at IRIF) with a ceremony at UNESCO opened to the public the archives of Softwareheritage.org, a worldwide initiative to create a universal library of computer programme source codes since the dawn of the digital age. .

BDA

11.05.2018
Amos Korman (IRIF) Amos Korman is co-chairing, and organizing the 6th Workshop on Biological Distributed Algorithms, to be held in London in July, the 23rd.
biological algorithm

Biological algorithm is a term used to describe the biological processes from an algorithmic, or computer scientific, perspective. It concerns questions such as what are the algorithmic challenges faced by the biological organism, and what are the algorithmic principals used in order to overcome these challenges. For example, when a group of ants finds a large piece of food and needs to decide its navigation rout back to the nest, what are the benefits and pitfalls of noise in their communication?
IRIF

27.02.2018
Peter Habermehl (IRIF) and Benedikt Bollig (LSV, ENS Paris-Saclay) organize the research school MOVEP (Modelling and Verification of Parallel Processes), from on July 16-20 in Cachan.

During the summer break the seminars have a reduced activity.
