Exchanging Postdoctoral researchers and PhD students

Under the project researchers have been traveling to meet their collegues in Taiwan and make joint researches. In particular Matthieu Dien went to Academia Sinica in Taipei for 10 months for a PostDoc staring from September 2017. Phd students Sergey Dovgal and Mehdi Naima have also made travels to Taipei in 2017 and 2018.

Workshop ALEA Young 2019


The project members are organizing the workshop ALEA Young 2019 which take place from May 19th to May 24th, 2019 in Normandy, France.

The workshop ALEA Young 2019 is part of a series of workshops
(Oxford’12, Paris’13, Bath’15, Vienna’16, Paris’17) about
random discrete structures arising from domains such that Computer
Science, Mathematics, Bioinformatics, Physics.

This year attendees will follow three lessons given by:
-Elise Goujard about flat surfaces and counting problems
-Irène Marcovici about probabilistic cellular automata
-Fiona Skerman about nice random graph theory
just as long and short talks given by the participants.
Also, special sessions will be reserved to work on open problems
brought by the participants (e.g. open questions or software

The workshop will be held in “le Domaine de la Tour” at
Saint-Pierre-Canivet (close from Caen in Normandy, France).

A website giving more details has been set for the event.

Meeting in Caen (January 31 – February 1)

French part of the project met last January 31 and February 1 in the University of Caen.

We were lucky to attend to the talks of Danièle Gardy (UVSQ), Julien Clément (UNICAEN) and Antoine Genitrini (Sorbonne Université). During the working sessions we were happy to work on analysis of text algorithm (Brigitte Vallée and Julien Clément), Boltzmann random generation (Martin Pépin and Matthieu Dien) and some problems around Binary Decision Diagramm suggested by Alexandre Niveau (UNICAEN).


Danièle Gardy : Compter les sous-graphes (Enumerating the subgraphs)

Julien CLément and Antoine Genitrini : La combinatoire des Diagrammes de Décision Binaire (The combinatorics of Binary Decision Diagram)

Computational Logic and Applications

The Computational Logic and Applications (CLA) workshops are a series of annual meetings (cf. https://cla.tcs.uj.edu.pl), whose main purpose is to provide a free and open forum for research on combinatorial and quantitative aspects of mathematical logic and their applications in computer science. The next meeting will take place in Versailles (France) in July 1-2, 2019. It will be  followed by a special issue of DMTCS dedicated to the same topics.

Topics within the scope of CLA include:
– combinatorics of lambda calculus and related formalisms,
– quantitative aspects of program evaluation and normalisation,
– asymptotic enumeration in computational logic,
– statistical properties of formulae, terms and programs,
– random generation of large combinatorial structures in computational logic,
– randomness in software testing and counter-example generation methods.

Tutorial and Workshop on Analytic and Enumerative Aspects of Combinatorics

  • Description:This is the second joint meeting between this project and the participants of our FWF-MOST project (http://rsd.stat.sinica.edu.tw/). The first took place in Paris from September 1st to September 2nd, 2016. The purpose of this meeting is to present recent research results of the participants of the two projects and discuss further joint collaborations. The meeting will start with a one-day tutorial which will be mainly geared towards students. Moreover, the meeting will be open to the local research community in Combinatorics (both students and researchers are welcome!).
  • Date:    Friday, October 27, 2017 to Sunday, October 29, 2017
  • Place:   Department of Applied Mathematics, National Chiao Tung University (NCTU)
  • Program:October 27, 2017: Tutorial given by Michele Soria (Pierre and Marie Curie University) and Bernhard Gittenberger (Technical University of Vienna)October 28-29, 2017: Workshop with approximately 10 talks
  • Accommodation:On-campus accommodation is limited; it’s more convenient but doesn’t include breakfast (however, there are many restaurants at NCTU’s campus). Off-campus accommodation, if further away from the campus, requires either a long walk or commuting by taxi (Hsinchu’s public transport system is less convenient). All places listed below can also be found on tripadvisor.On-campus guest houses:1. Guest house II $1,000/night; $200+ for double occupancy Guest house III, $1,500 NTD/night(single occupancy); $200+ for double occupancy Landis Inn Chuhu, $3,300 NTD/night, complimentary breakfast; 5-minute walk to NCTU (ca. 350m from the main gate)
    2. Berkeley Hotel $1,800 NTD/night, complimentary breakfast, 20-minute walk to NCTU via the campus of the neighboring Tsing-HuaUniversity
