As I've announced before, I was the chair of the Scientific Committee at The 16th Central European Olympiad in Informatics (CEOI'09). I will have a few non-technical post on the experience, but in the next 6 posts, I will simply let you enjoy the problems.
- You can form your own impression on the level of these contests (I think it is quite high, and it will allow us to recuit many researchers down the road. Consider that one has to solve and implement 3 problems in 5 hours.)
- These are great algorithmic puzzles, of the kind that is hard to come by (as opposed to math puzzles, which are everywhere, but I find boring).
- You may finally answer the question: Are you smarter than an 11th grader? :)
