Bayan — live coverage
By ivanromanov, 12 years ago, In English

Hi everybody, it's 11:10 local time at Tehran, I'll tell you how the Bayan Programming contest 2013 (1391) onsite Finals is progressing.

22:17. Peter50216, cerealguy and Egor are top-three! Congratulations!

22:05. Closing ceremony. The rejudge took place for one problem.

18:30. Not everything of Funkoders has been judged yet, so the results of this additional fun contest will come later.

18:29. It's over!

18:27. Announcement: two minutes to the end of the contest. It should have 5 though.

18:10. It's a fun competition, so there are two guys entertaining competitors and spectators:

18:04. Every couple of minutes one of the baloons exploid, making a person next to it jumping up.

17:54. Only the first submission will count. There are 15 problems. Competitors hope that the problems are not harder than in the main round.

17:51. Let's begin!

17:50. Funkoders challenge will last 42 minutes and will contains lots of problems.

16:26. The contestants are having lunch now, afterwards the Funkoders Challenge is scheduled — a contest for fun. While you are guessing about the winner's name, I'll announce the winner of our "guess-the-wireless-password" contest. Actually, nobody had it 100% correct. The password was "bayan", so MikeMirzayanov who suggested "Bayan" is winning a special prize: he won the right to contribute to Codeforces completely free of charge the whole day tomorrow, on Sunday! Congratulations!

16:05. The contest has finished!

16:00. Five minutes until the finish of the contest.

15:35. Half an hour before the contest end (again). Here are some details about "rejudge". The score for each problem depends on submission time, number of wrong tries and number of people successfully solved that problem. So, after the contest end everything will be rejudged to double-check and make sure the final results are correct. Discrepancies, if any at all, will be investigated manually.

15:19. Announcement: 45 minutes until the end of the contest. Ranklist will not be updated anymore. Some rejudges may take place.

15:13. Current standings:

15:05. Announcement: according to the jury team decision, the contest duration will be extended by 30 minutes.

15:02. Half an hour till the end. I see a small chance that the contest will be prolonged.

14:45. With baloons it looks like this (larger photo here):

14:36. There are few more people who solved one problem: havaliza, Nick name, liympanda and cheshme.

14:34. Baloons are distributed now for every solved problem: green is assigned to the most popular task F.

14:20. Announcement: please check clarifications, the constraint for interactive problem is published now. The interactive problem will not be removed from the problemset, although this possibility has been considered before.

14:18. The problems are hard, there are not many submissions.

14:16. Nicknames of Galapagos, fmwviormv and Haas do not match those on TopCoder. Also, cerealguy uses a nickname mikhail in the contest today.

14:11. We have a new leader: peter50216 with A, F, G. Then cerealguy — F and G, mruxim, Galapagos with A, watashi with G. Then come anrieff, fmwviormv, kelvin, Haas, Egor and Dmitry_Egorov with F.

13:59. watashi is on the second place at the moment with problem G. He is followed by mruxim, peter50216 and Galapagos who solved problem A. Three more people with problem F follow: kelvin, Egor, Dmitry_Egorov.

13:55. Almost the half of the contest has passed, and we have just 8 people who solved at least one task. Just recently cerealguy has got his second accepted and he dominates the ranklist with problems F and G.

13:53. I hope you missed me. I missed Iranian food so much, so I had to have a lunch break. Standings follow.

13:01. Announcement: please check clarifications. (One of the constraints has been fixed.)

12:57. It is very quite in the contest area. Egor is the only one with his headphones on, he codes something thoroughly, looking at the problem statements frequently.

12:43. There are 7 problems for three hours. Unfortunately, there is no standings table available on the web.

12:40. cerealguy seems to be the only one who brought Mac to compete on. He seems to write a code for at least 3 minutes now.

12:33. Contestants have printed versions of problems.

12:32. THE CONTEST HAS STARTED!

12:31. My laptop shows Swiss time, which is 10:01 now, and I'm getting very good in adding 2.5 hours to it to put a timestamp in Iranian timezone to each update.

12:28. One problem may be removed from the problemset, because the are some difficulties with it. We hope to begin soon.

12:26. By now everyone should be logged in with their username and password.

12:18. Four executables are available: {32-bit, 64-bit}x{Windows, Linux}. SeMeKh: "I hope nobody has any other OS."

12:14. Contestants can test their solution to the interactive task locally, providing the simulator with N (size of task) and a random seed. The simulator will generate a hashed result ("secret key"), which can be submitted to the judge.

12:11. Mehran apologises for the delay and encourages the participants to make themselves familiar with interactive problem. Every announcement is made in English and in Farsi.

12:05. Here is the contest area:

12:02. There 56 contestants here, representing Iran, Russia, China, Taiwan, Bulgaria.

11:52. All of the password guesses in comments correctly spotted the main keyword of the contest :-) But there is no 100% correct answer yet.

11:49. Network issue is resolved. SeMeKh announces, that one of the problems will be interactive, the binary executable will be available.

11:38. It has been anounced, that one of the contestants has problem with network. We'll try to fix it and start as soon as possible.

11:27. All contestants have entered the competition area. Mehran, one of the problemsetters from Bayan, has announced the Wi-fi network name and password where contestants have to connect. Can you guess the password?

11:13. While you wait for updates from me, you can read the first part of my nano-research on how it works (can also be read as "IT works") in Iran. Or just look at the pictures from the first two days in Tehran.

11:11. With a delay of about one hour contestants started to enter the competition area.

    Strictly speaking, you are right, these are pairs of individual narrow tables.

    Could you please tell what does this mean:
    برنامه نویسی و پی اچ پی

    It seems to be a tag or a theme, but Google translates it as "PHP programming" =)

There are a couple of things about scoreboard:

  1. It currently work incorrectly. Later you send problem — more points you get

  2. Despite frozen scoreboard queue was not frozen, so cerealguy solved 4, anybody else 3 maximum

  3. But my and peter50216 answers (there actually were only one input file for at least this problem) for Museum (Task D, I think) are the same baring precision error (and I think my precision is correct)...
