In 2013 Yandex will host an open programming championship on the new Yandex.Contest system, with original rules, prizes, monetary awards and an exciting final round in St. Petersburg, Russia. But the most important part will be great problem sets, made by Belarusian, Japanese and Polish problem setters. Registration opens on May 30. Full information about the schedule of events is available on the Schedule webpage
Specifics of the tournament
Yandex.Algorithm 2013 will be scored using the TCM/Time system and consists of six rounds: test, qualification, three elimination and final rounds. The final will be held on August 21–23, with the main event taking place in St. Petersburg’s Vladimir Palace. Each round will last 100 minutes and include a set of algorithmic problems. The test round will give you an opportunity to try out the new Yandex.Contest system and familiarise yourself with the TCM/Time system. Two hundred and fifty participants will qualify from the test round directly to the elimination stage of the contest. All who have registered for the Yandex.Algorithm competition can take part in the qualification round. The 2,000 best contestants who have solved at least one problem will advance to the elimination stage.
The elimination stage consists of three rounds, with each round starting at a different time to give contestants from each time zone the opportunity to choose a comfortable participation time. A complex advancing system will determine the best of the best.
Participants of the elimination stage earn score points based on their performance in each elimination round according to the Grand Prix 30 system. You can read the full description of the system on the Rules webpage
The top 4 contestants from each elimination round (of those who have not yet advanced to the final round) will be invited to the final. Another top 9 contestants based on the cumulative score of two best out-of-three elimination rounds will also join the top contestants in the final round. Of all those who have not yet advanced to the final round, the top 4 participants according to the cumulative score of the whole elimination stage will be invited to the final round, giving a total of 25 finalists: 12 based on one round score, 9 – on two best rounds, 4 – on the overall performance in the elimination stage.
The Grand Prix 30 system allows the finalists to include not only the top participants of each round, but also stable performers who have participated in multiple rounds.
TCM/Time rules are similar to ICPC rules with the difference of “blind” submissions. Upon submission, blindly submitted solutions are tested only on a sample test set, and the overall result on the problem is shown only after the end of the contest. There is a bonus for the risk – successful blind submissions will subtract penalty time based on the number of contestants who have solved the given problem. As a result, total penalty time can even be negative! You can read the full description of the TCM/Time system on the Rules webpage. Read them carefully.
The testing system supports the following list of compilers:

The final will take place on August 21–23 in St. Petersburg, Russia, in the former palace of Grand Duke Vladimir, built in 1870 on the Neva River embankment near the Hermitage museum. In the palace halls there is a significant collection of Russian paintings as well as the library of Emperor Alexander II.
