Hi Codeforces!

I have a great announcement for you. This month, we're holding the second Codeforces Blitz Cup! Remember all the WA1s and CEs we've seen from LGMs stressing out to submit before the opponent? They are coming back!

The Codeforces Blitz Cup is a single-elimination personal tournament where matches follow the special Blitz Rules. In short, each match is a 40-minute PvP contest, where problems open one by one, and only the first AC counts. The players can't use any help or prewritten code except a small template, and we get to watch them think and code live.

Check out last year's final rounds streams: day 1, and the final day 2 to get the feel for the format.

  • Eligibility: Grandmasters or above
  • Registration deadline: February 12, 10:00 UTC
  • Elimination rounds: February 13th to 26th (free schedule)
  • Live finals: February 28 to March 1 (online)

See you blitzing!

UPD

And we know our finalists! Congratulations to __baozii__, 244mhq, Amoo_Safar, Dominater069, ecnerwala, errorgorn, feecIe6418, Geothermal, ksun48, makrav, Ormlis, qiuzx, SSerxhs, tourist, turmax, Um_nik, and see you all on the livestream!

Just to clarify, we have to free from 28 February to 1 March, but what period of time does this refer to specifically (starting from what time on 28th Feb and ending at what time on 1st March)?

    You can refer to last year's schedule: /blog/entry/140425. We will likely group Saturday matches based on timezone; and we'll try to accomodate requests for Sunday matches timing.

Would it be possible to add the feature for all codeforces users to create their own Blitz matches just like mashups? This format sounds really fun, and it would be nice if we could just challenge a friend or host our own tournaments in our groups/universities

    Blitz matches are a great idea and a very cool feature for the whole community. However, I would like to point out that full-fledged blitz tournaments are much more interesting for all members of the community, regardless of the rating.

    These can be single-elimination or double-elimination tournaments. It is possible to hold tournaments in a round-robin system. I would like to note that these formats can be combined — the tournament may consist of a group stage and a playoff stage.

    I am absolutely confident that when the technical possibility of holding such tournaments is realized... They will be interesting to a huge number of people. I would like to note separately that these tournaments can be a great motivation for very novice programmers.

As a participant, I inputted the bracket here: https://challonge.com/1p4x3m5g

I'll keep updating it from time to time (ideally more than twice a day) so everyone here can be kept up to date with the matches/results.

Also there is a prediction feature so feel free to submit your predictions for the cup :)

Edit: KAN made an official bracket

Is there a link where I can view the problems that appear in a match. I wanted to try out solving them for fun and see my speed for comparison. Simply, searching for the problem name does not work always for the really old problems.
