If you are registered on Timus, then you should have been received e-mail with invitation to this contest. The contest will be on 19 November in 11 Moscow time.

It was a junior championship but it was 'a little' harder than it was intended. As I remember, Merkurev solved all the problems with only 15 minutes to go, so I think that this contest may be interesting for participants with different levels, up to the strongest ACM teams.

The duration is 5 hours, standard ACM rules. It is a team (up to 3 participants) contest but you are welcome to partcipate individually too.

The authors of the problemset are Um_nik, sivukhin, kb., Tinsane and crassirostris.
