Hello, Codeforces!

Today, 17th of October at 17:35 MSK Codeforces Round #377 for second division participants will take place. As usual, first division participants are able to participate out of rating.

The round problems are taken from the problemset of regional stage of the All-Russian school team programming olympiad which was taking place yesterday in Saratov. The problemset for onsite competition was invented and prepared by Mike MikeMirzayanov Mirzayanov, Ilya IlyaLos Los, Danil danilka.pro Sagunov, Vladimir vovuh Petrov and Roman Roms Glazov. We are thankful for pre-solving competition problems to many of Saratov State U teams' participants. One problem in the round will have a bit harder version than at the competition.

Nikolay KAN Kalinin and Tatyana Tatiana_S Semenova helped us preparing problems and translating for the round — thank you! Thanks to Mike MikeMirzayanov Mirzayanov for the Codeforces and Polygon systems.

There will be 6 problems and 2 and a half hours to solve them at the round. We wish you the best luck!

If you are a participant of the yesterday competition in Saratov, please, do not register for the round and do not participate in it, also do not discuss the problems before the round ends.

Hi everybody!

Tomorrow at 09:35 UTC there will be Codeforces Round #376 that is dedicated for the second division. At the same time there will be a Moscow School Team Olympiad, and, as a nice tradition, we bring you a CodeForces round based on its problems. Unfortunately, this time we weren't able to come up with a good problemset for a first division contestants, but, as usual, we invite first division to participate unofficially in this round.

Problems were prepared by timgaripov, platypus179, wilwell, Flyrise, ipavlov and vintage_Vlad_Makeev under my control. We would like to thank members of jury of the Team Olympiad: Endagorion, Helen Andreeva and GlebsHP, who also works as a coordinator from the CodeForces side. Also we are very grateful to MikeMirzayanov for a Polygon system that makes problem preparation and coordination of many involved people much simpler, and for a great CodeForces community that we are all part of.

We suggest you 6 problems for 2 hours. Good luck!

Hello, Codeforces!

The seven Moscow International Workshop ACM ICPC 2016 will be organized in collaboration with the Moscow Institute of Physics and Technology, ITMO University and the MSU Faculty of Mechanics and Mathematics from November 8 to 18.

This year, due to the tight schedule of the Subregionals, the term of registration is extended until October 24 for participants from Russia and the surrounding countries who don't need time to issue a visa and until October 15 who participants who do need a visa.

Teams now also have an opportunity to participate in the shortened version of the Workshop from November 8 to 15.

Last year, teams from 20 European and Asian countries participated in the Workshop, and the number of new universities that sent teams to the Workshop grows each year. The majority of participating teams not only become ACM ICPC finalists but win medals too: 8 out of 13 medalists of ACM ICPC World Finals 2016 participated in the Fall and Spring Workshops at MIPT.
