  • high-performance scientific computing
  • graphs, hypergraphs, and combinatorics
  • algorithms and complexity
  • large-scale optimization


The activities of the seminar focused on combinatorial issues in high-performance scientific computing. The activities included:

  • eight one-hour invited talks
  • thirteen 20-minute contributed talks by participants from seven countries
  • six software tutorials
  • three round table discussions

Participants also enjoyed one of two recreational activities in a free afternoon (a long hike or a trip to Trier). As usual in Dagstuhl seminars, participants also engaged in lively informal professional (and personal) discussions during breaks, at meal times, and late into the night in the cafeteria / the wine cellar.

Two of the organizers, Uwe Naumann and Olaf Schenk, are working on a proposal to CRC Press for publication of a special collection of articles on CombinatorialScientific Computing in their Chapman & Hall/CRC Computational Science series. The purpose of the book is to provide the first collection of references for a diverse community of researcher working in different aspects in the exiting field of CSC. The content is strongly motivated by this seminar including survey articles as well as tutorial-style software guides. Potential readers include graduate students, young researcher, scientists in mid-career, and senior investigators from both academia and industry. Some are experts on graph combinatorial aspects, some are focusing on theoretical analysis, and some are more directed towards software development and concrete applications. Outreach into areas of science and engineering that face similar combinatorial problems as the CSC community is a major objective.

Dagstuhl's Impact

Bitte informieren Sie uns, wenn eine Veröffentlichung ausgehend von Ihrem Seminar entsteht. Derartige Veröffentlichungen werden von uns in der Rubrik Dagstuhl's Impact separat aufgelistet  und im Erdgeschoss der Bibliothek präsentiert.


Es besteht weiterhin die Möglichkeit, eine umfassende Kollektion begutachteter Arbeiten in der Reihe Dagstuhl Follow-Ups zu publizieren.
