Yandex.Algorithm Finals
By Michael, 13 years ago, translation, In English

Hi everybody!

Yandex.Algorithm finalists were gathering in Dolgoprudny... Everybody in their own unique way :)

dzhulgakov, pieguy, levlam and Progger turned out to be the most organized and arrived at the start of the Summer School. They've already socialized with other participants and began solving and competing in the practical bioinformatics problem using a distributed Hadoop cluster accessible for all school participants — good for them! Two Japanese buddies rng_58 and wata landed at Sheremetyevo airport on July 13 at 17.55, and an hour later they were already receiving their badges from me. Their fellow-countryman LayCurse mixed up the dates and took the tickets for the same flight but for July 14 :) tourist with his father came in the morning on July 14th, and dolphinigle landed yesterday late in the evening and told me I was the first man in Russia he met who spoke English :) ivan.metelsky "burst" into the room of the School organizers sleeping after yesterday's party at 8 AM; he got there himself without any instructions :) e-maxx arrived at Moscow by train at 10.38 in the morning and made his way directly to the competition with our other friends from Saratov - with some adventures on the way: the electric trains to Dolgoprudny have a break from 11.10 till 13.40. ktuan decided last minute that he won't spend his last univercity vacation for the finals, and Burunduk1 seems to have been too busy with teaching high school students and didn't answer my e-mails and phone calls (tut-tut, Sergey!) — I wonder whether he will be coming last minute. Petr will drive here from Moscow just before lunch. My intern zeliboba studies at MIPT and lives in the same building where all the other participants of the Summer School, so he'll probably come to the contest floor last :)

Everybody can register and participate in the round as usual. Those who don't participate in the onsite round will be out of competition, but the round is rated for everybody in Div-1.

I remind you that the contest time is unusual today: we will start at 16.00 The problems are harder than usual in Div-1 today — looking forward to a bitter struggle!

Update: full results

Something is wrong! What is this : ftiasch took 12 place and got only 78+ to the rating...

Edit.: It looks like you accidentally switched div 2 rating mode.

    Yeah, Petr got +58 for winning Yandex Round 2, but only +22 for winning Yandex Finals, not very logical indeed.

    Perhaps it is because the participation rate is low today.

    Maybe some scaling could be introduced in the formulas for rating changes.

      There should also be some scaling over time, so that rating graphs will be less erratic, and ratings will be more accurate.

The problems were nice and challenging. Is somebody going to write an analysis?

Why it's not rated for Div-2? When I was registering, it showed me nothing about this.

    It seems discrimination to me as it wasn't some kind of Div-1 contest.
    Either previous rounds shouldn't be rated for Div-2 or rated/unrated thing should be same for both Div-1 & 2 (except the finalists). 
    Moreover, if it suppose to be unrated for Div-2, it should be written in registration page.

        I don't think everyone first reads invitation letter in mail then register in here.

Is there a contestant who is not on-site ranked 2nd? I see Petr is 1st and dzhulgakov is 3rd in their information pages.

The problem D... I haven't read it yet, but: it has 4s time limit and 72 tests...

Test 71 and 72 (apparently) are similar (same n, m, k) so it is very sad to see that a solutions passes the 71-th test (on the edge of the 4 seconds limit) but not the 72-th...

from 1 to 70: ok
71-th: 3980 ms (ok...)
72-th: TLE

I think tourist's reaction was something like this. (Especially because he sent the solution just 25 seconds before the end of the contest)
