I wanted to create this blog because there will probably not be really much discussion of solutions in the award ceremony (currently in progress). Also people who aren't finalists themselves can't see that anyway.

I'm interested to hear approaches of the higher-scoring finalists. (We, TÜ Randomized Algorithms did not do anything interesting :D)

A bit on the negative side: this seemed to be not be a 4-hour contest at all. The problem was kinda complex, I felt that I spent all the contest swamped in implementation, not being able to implement even 1/10 of the ideas I had. Well, it's also partially our fault for coming to troll in the finals with a 2-person team :P.

Also, did anyone manage to use the visualizer?
