18th Graph Drawing Contest

Call for Participation

The 18th Annual Graph Drawing Contest shall be held in conjunction with the 19th International Symposium on Graph Drawing (GD 2011). Except for the challenge competition, which takes place during the conference, all submissions are due by September 19, 2011 (23:59 CET).

This year, the contest has the following three topics: angular resolution, a composers graph, and the graph drawing challenge.

Angular resolution

Graph drawing challenge

The challenge will be held during the conference in a format similar to a typical programming contest, where teams are presented with a collection of challenge graphs and have approximately one hour to submit their highest scoring drawings. This year the challenge shall focus on minimizing the length of the longest edge in an orthogonal layout. The longest edge can be a bottleneck for many applications, hence minimizing its length is important.

For details, see here.


Submissions for the composers graph and the angular resolution tasks must be received by September 19 (23:59 Central European Time) and should include the following information:

  • names and email addresses of the contributors,
  • a picture illustrating the graph, and
  • a brief description on how the layout was produced.
Electronic submissions are strongly encouraged. However, if your drawing requires special printing because of size, resolution, or color constraints, you are encouraged to submit via hard-copy. Acceptable electronic formats include PDF and PostScript for images.

All contest submissions should be sent to

Carsten Gutwenger
TU Dortmund
Otto-Hahn-Str. 14
44227 Dortmund, Germany


Cash prizes and medals will be given to the top finishers in each category. In each of the five categories (angular resolution A + B, composers graph, challenge automatic + manual), the winner will receive a prize money of 200 Euro.
