      Agree, Geothermal is a beast in term of solving easy problems fast! He finished 1st place in almost every div3 rounds!

    Can I bet money against you? I would bet anything, because what you are proposing is literally impossible given the bracket.

      Bet 1M$ on that. Then mnvbmar just gonna go to the KAN and ask him to change the bracket for 250K$. Another 250K$ he will give to contestants for ensuring that tourist vs turmax will happen. Easy 500K$ profit for Andrew and easy profit for everyone else except you, Umnik.

Out of curiousity, how does one implement opening problems feature during the contest? It would be really fun if everyone can use the blitz feature!

After 7th round:

tourist = conquerer of conquerer_of_tourist

That means:

conquerer_of_tourist = conquerer_of_(conquerer of conquerer_of_tourist)

That also means:

Tourist = conquerer of (conquerer_of_(conquerer of conquerer_of_tourist))

...

(an infinite recursion)

    I agree, something tells me if tourist solved G, they wouldn’t have given Golovanov the same courtesy of a free rematch. Also “unproven” is a bit silly, either you can hack the solution or you can’t.

      they would have. The decision was made before the problem was solved and also a new contest was also made before it was solved

    So basically a controversial problem from an old contest was the G problem which has no proven solutions and in contest very few people solved it. Golovanov339 ended up solving it but he was not awarded the win because this would be unfair for tourist.

Pure injustice.

If there is really a problem, the contest should be held completely from the beginning.

3 people final should be great but the rematch is also a good option

True final thas in match "14" (tourist vs Golovanov399). It was so close and interesting. Thanks for this good weekend!

P.s. Golovanov399 was really best opponent for tourist.

    I agree the match was unfair, but that also doesn’t mean Golovanov would have beaten Geothermal

Why does tourist and Golovanov399 need a rematch?

Vote: I like it +54 Vote: I do not like it

It seems that there needs to be some form of verification, maybe extra 5 minutes to check that tasks are okay — it is really sad that people get an "unwinnable" match before the last problem and do not know it.

Would have liked it if Geothermal won it due to me losing to him obviously, but it was a great tournament despite some of the issues (and I hope my PC will not get crashed by monitoring software again) ).

Thank you to all organizers for making this happen!
