SCAN 2010
14th GAMM-IMACS International Symposium on Scientific Computing, Computer Arithmetic and Validated Numerics
ENS de Lyon, France, September 27-30, 2010

The 14th SCAN conference will be held under the auspices of

Scope and topics

The SCAN symposia gather researchers in scientific computing who work on the numerical quality and the verification of their computed results. The scope of the SCAN conferences covers all aspects, from theory to implementation and applications, with a strong emphasis on verification of computed results, as well as on arithmetic, programming, and algorithmic tools for this purpose. The contributions provide competent and concise information on recent hardware and software standards, developments in computer arithmetic, self-validating numerical algorithms, stochastic approaches, algebraic approaches, and applications in various fields.

The goal of the SCAN 2010 conference is to offer a panorama of the techniques and tools used to guarantee numerically computed results. These techniques include, but are not limited to, interval arithmetic, floating-point as specified by the IEEE 754-2008 standard, exact computations, symbolic approaches, formal proof, sensitivity analysis...

Near the Part Dieu shopping mall:


Lyon is easy to reach, either by plane then by the Rhônexpress line (get off at Lyon Part-Dieu), or by train (French version, or English version). You may also consider landing in Paris and use a 2-hour connexion by fast train with Roissy Charles de Gaulle airport.

How to go from Debourg subway station to the SCAN 2010 conference: When you leave the subway train, take the exit on your right, go straight to the pharmacy, turn right and cross the street (avenue Jean Jaurès). Straight on through Challemel-Lacour street, then Place des Pavillons and the pedestrian allée d'Italie. The entrance of SCAN 2010 is left to the fountain.

Publication after the SCAN 2010 conference

There will be no formal proceedings of SCAN 2010.

However, the journal Computing, Springer Publisher, Vienna, will publish strongly refereed, high-level presentations in regular issues of Computing.

We apologize for troubles some of you may have encountered during their submission to Computing. This was due to a slight misunderstanding, which is now clarified. The deadline has been postponed, please submit your contribution as soon as possible. Please also send us (Götz Alefeld and Nathalie Revol) a copy of your submission.


  1. The results have to be new: no short or extended versions of results already published otherwise.
  2. Each submitted paper will undergo the usual refereeing process of Computing: at least two anonymous, external referees.
  3. There is no formal page limit. However, we suggest to limit contributions to 10 pages (15 pages for invited talks).
  4. There is no official deadline. However, we recommend to submit contributions no later than February 28, 2011. This will help to ensure that all contributions can be published in consecutive issues of Computing.
  5. The submission has to be done via the paper submission system of Computing. However, do not remove anything from the first page, otherwise your contribution will not be recognized as a SCAN 2010 contribution.
  6. In particular, do not delete the footnote on the title page mentioning the relation between the submitted paper and the SCAN 2010 conference. This footnote should take the following form: The authors have presented the results of this paper during the SCAN 2010 conference in Lyon, September 2010.
  7. Please also send us (Götz Alefeld and Nathalie Revol) a copy of your submission.

If you have any question, please contact Götz Alefeld and/or Nathalie Revol.
