MSU is my guess for the winner. MIT and Warsaw seem quite strong as well. Japanese were dominating IOI in recent years so I wonder if they'll be equally successful in icpc in the next 4 years.

And I think there will be some bonus due to the equal number of solving problems and the similar penalty. Just like last year. And I have faith in my host team — Zhejiang U.

    I don't think Cambridge will even get a medal. Their team has a world-class mathematician. But that's about it. They don't have an outstanding algorithm guy (e.g. someone on Um_nik's level).

    Uh, that's because their Codeforces handles (and therefore their names) are not updated. Are they the same team as last year?

    Also we may need to see the team's actual performances in the Workshops. TBH I didn't know much about SJTU 2018 team before MW.

Princeton University: Yuping Luo: roosephu Dingli Yu: SillyHook06 I don't know the profile for the last guy — I think he didn't participate much on CF.

Also, regarding Dingli Yu's username, he also seemed to have competed as Leo_Yu, but as this notes (https://codeforces.me/blog/entry/11895?#comment-168674), SillyHook06 is almost definitely Leo Yu as well.

  Vote: I like it +51 Vote: I do not like it

OK so here we go again with my yearly random predictions with as random accompanying comments. ^^

1. Nanjing University

Strongest team? No. But a very solid team, and this year it's China's turn to win again. There will be an obscure mathematical problem that one of them knows that will put them ahead of Moscow State Uni.

2. Moscow State University

Impressive strength with two top 10 members. Would win on a normal day, but today is no normal day.

3. MIT

Three nutellas and an outstandingly high average level. Even if one member has a bad day there are two other who can cover up. Or does it mean that everyone will relax and no one will step up in dire times? Could happen, but ecnerwala will bring the winner's mentality from the DGCJ 2017 win, which will take them back on track and guarantee a gold medal.

4. University of Warsaw

Maybe a bit too dependent on Radewoosh? So will Radewoosh have a good day? Initially no, but then he'll remember his DGCJ 2018 win and make his team surge towards the end.

5. KAIST

I'm maybe just imagining, but in my mind Korean teams tend to have a good start. And this year will be no different. KAIST will be in the lead after 2:30h, but will then "hit a wall" and start dropping to bronze position. A ko_osaga who's luckily in shape today will bring them back into the fight for gold during the last hour, though in the end Poland will prove too tough and they will have to settle for a (the best) silver medal.

6. MIPT

Overall solid Russian team, which is a proven recipe for success in this contest. :) Will never be up there fighting for gold during the contest, but will keep solving problem at a steady pace which will give them a comfortable silver medal.

7. Tsinghua University

Will have performance like a roller-coaster during the contest. They will be the first to solve a problem, but then they will start to sink in the ranking, but then again come back 3-4h into the competition.

8. University of Tokyo

Does indeed have a solid overall performance, but lacks that extra edge needed today to solve that extra hard problem. Also, UTokyo tend to underperform in my view, however (as a former exchange student there) I'll secretly cheer for them. :)

頑張れ東大！

9. Sharif University of Technology

The revenge for the last 2 years will finally come! \o/

10. Beihang University

Chinese underdog team? Maybe. But they have good overall strength and that will be important today.

11. St. Petersburg ITMO University

It's ITMO. Enough said.

12. University of Cambridge

Do I truly think NWERC will grab a medal today? Maybe not, but I have to root for what little Swedish representation we have. :)

Kom igen nu Davve/_h_!

13. University of Waterloo

Might grab one of those extra bronze medals that appear from time to time. And again, I gotta root for what little Swedish representation we have. ;P

Kom igen nu Jocke/Xylofo!

      I guess I predicted the wrong South Korean team for silver medal. Though you were "still in the game" ~2:30 into the contest. ^^

      What happened? Too much time wasted on B and F?

      (Also, I assume there are multiple teams who wanna cry. :S)

        Thank you for giving me a chance of whining XD

        Too much time wasted on B and F?

        I think that's almost exact. Until 4 problems we were kinda OK, so I went for G and teammates went for B. My G was a suffix-array based $$$(n+q)\log^2 n$$$ which was quite hard (I had to almost rewrite the code) to constant optimize. I don’t know why it was TL, but..

        Whatever I got AC on G and went to F. There was several reasons for my decision, which was:

        • J literally shouted like "you will somehow make mistakes in rounding blah blah you-don't-wanna-care stuff, don't try to solve this", I wanted to avoid that.
        • I thought my teammates will have time and can solve J
        • F was indeed solved that moment by MIT. I think J wasn't that much solved then.
        • F is a DS problem and I like them so much. For me, it was the only problem that I wanted to try in the contest. I still think F was the most interesting problem in WF2019.
        • I was stupid to understand why my solution was wrong, and in what aspect.

        In a hindsight, it was a bad decision, but whatever. I think I found the countercase like 30 mins after the contest, which taught me that I was stupid af. It wasn't a productive contest for our teammates, as they got B in 290min (AFAIK it was a single-letter typo)

        After the contest ksun48 thanked me for G, which he said their team solved because I taught him the faster (linear?) Aho-Corasick based solution on the same problem posed before. I barely remember when was it, but I just decided to believe it and get some ego boost.

          That was quite unlucky :(

          However, by any chance, did you misread the condition of constant $$$l$$$ on problem J? As $$$l$$$ must be a positive integer, it's not very hard to come up with a solution that uses only integer arithmetic. The implementation wasn't that error-prone either.

            I think I knew that, and I also had a clear idea how to code my solution. Still I’m afraid of playing with rounding stuffs. I thought I will quickly code and got lot of WA. Maybe I’m just very weak at such, or just too afraid.

      Well at least you were first to solve problem A. :)

      But yeah, I thought that this year would be a good one for Chinese teams, but it turned out to be quite the opposite. ^^ Your team in particular seems to have lost valuable time on fixing B/G/H?

      Though many teams could've easily grabbed a silver medal had they only decided to attack problem I, which a bit funnily got solved by the team third from the bottom. xD
