Congratz to you all :) just to hearing how your guy cheering each others during result announcements, this regional seem like your reunion lol.

I would like to write out some expected and unexpected happening during the contests.

  • We dont expect E to be highest numbers of solve. In fact, we expect it to be J,K or L
  • Although we expect L to be easy, surprisingly, there're some team with 9 problem solved while leave L blank
  • C are remain unsolved, as expected.
  • G are much easier than we expected. Our intended solution are to use some linear algebra method.
  • Some top team D submission are close to the answer. While all of team try it using searching-like method (hill climbing, binary search, etc), it intended solution are different.

UPD: If you have any comment about problem sets or our organizing, please let's us know. I want to see some feedback too

    Everyone I know have this same comment: Why did you guys shuffle the problems on scoreboard? And why do you not answer the correct order to participants? This never happens in any regional, and affected performance of many teams. I thought this was an unexpected behaviour of the scoreboard, until I see the following comment in JavaScript code:

    ** I HAVE CREATED SHUFFLE COLUMN METHOD CALLED RANCOL() FOR SHUFFLE PROBLEM AND ADDED SOME CSS STYLE FOR TABLE **
    --MarRTaN I., September 2013
    

    WHY?

    Other than this, I think everything else was smooth :)

      Okay, first, I have to say that I'm not the decider. AFAIK, every contests held by us (Chulalongkorn Univ.), done this for a while. Since this is our first regional, it is normal that foreigner team don't know this. And our Prof. said that there're no rule to prevent us from doing this(I believe we do talk to Asia director). So it's as you see.

      This might become practical or get rid, we don't know.

      But if someone personally ask me which way do I prefer, I prefer not to hide the order as well.

        Of course, I'm not putting the blame on you. I'm just hoping you can pass our comments to those who make decisions. If things do not change, this should be announced before the contest.

        And another thing, the way this "feature" was implemented is stupid. You can easily find out which problem is which, if you know basic JavaScript. This creates unfair advantage to some teams.

I just found this blog post because of the recent Thailand regional post :)

Thanks for the comments during the contest! Since almost everything from this regional had been deleted quite long time ago, it's hard for us to recall what happened during that contest.

I was in that contest! This is my team: https://codeforces.com/team/6065
