In 2020, with the support of XTX Markets, 6 rounds of the Codeforces Global Rounds were held. Each round was common for both divisions. All such rounds were rated for all participants. At each such round, 50 brand T-shirts were handed out, and we gave T-shirts to all problem writers!

I say a big thank you to XTX Markets (and personally to Yuri Bedny and Alexander Gerko) for supporting Global Rounds. Without your help, we could not host them! I sincerely admire companies like these who come to support and develop the community that some of their employees come from. It will be great if other companies follow the example and also offer their help. We need it!

The prizes for the 6-round series in 2020:

  • In each round, top-100 participants get points according to the table.
  • The final result for each participant is equal to the sum of points he gets in the four rounds he placed the highest.
  • The best 20 participants over all series get sweatshirts and place certificates.

Final results (and congratulations!):

I'm curious about the criteria the organizers used to create the table... Anyway, I expect to participate more next year :)

Why is "173 LynCean" grey? They placed 44-th out of 11k participants, but only got 945 rating for that.

It would be nice to give shirts randomly to low-rated people so that it keeps them motivated.

    While I understand your sentiment and also want free shirts, I feel like this incentivizes improvement, instead of just incentivizing particpation.
