There were plenty photos taken at the workshop in Bad Honnef. Hans took quite a lot of photos. Derek and Mitre also provided their share. Thank you to all the photographers that sent their photos to us, so we were able to put them up for you for viewing and downloading.
If you also have some photos from WG 2004 yourself and want to share them with the rest, just send them to Christian.

We have two archives to download all photos at once:
Very large archive with all photos (180 MB)
Archive with all photos in 800x600 (10 MB)

Below you find thumbs of all 180 pictures taken. Click them to view photos in 800x600.


At WG 2004 we had two invited talks that were not printed in the preprint of the proceedings. Due to great interest, the speakers were kind enough to give there slides to us. Here you can download the following slides:
Derek G. Corneil: Graph Searching with Emphasis on Lexicographic Breadth First Search
(scanned, zipped GIF - 2.1 MB)
Roger Wattenhofer: Wireless Networking - Graph Theory Unplugged
