Textbook from Springer: Parameterized Algorithms by Marek Cygan, Fedor V. Fomin, Lukasz Kowalik, Daniel Lokshtanov, Dániel Marx, Marcin Pilipczuk, Michal Pilipczuk, Saket Saurabh Springer -- Amazon -- Barnes & Noble -- Official book homepage |
I enjoy hiking, skiing, fantasy, sci-fi, tennis, cognac, parmesan and soccer. A couple (now 10) years ago I starred in Fana school theatre. I'm also involved with the Norwegian high school Informatics Olympiad, NIO. Most of the reasearch I do is in algorithmic graph theory. My Phd. is in parameterized algorithms and complexity. Check out the Parameterized Complexity Wiki. I'm project leader for BeHard, a four year research project on Kernelization funded by Bergen Research Foundation and University of Bergen. |
