The rumours on the google sheet was proven to be correct! Alas, Ram has qualified because INOI coordinators found testcases to affect other solutions but not his. This time the cutoff was 39/200! I got 39 but after they rechecked it I got 1 WA on 1 more subtask so I did not qualify!!!

This is pathetic. They are trying to make others fail just so that Ram can qualify! T1duS agrees with me

Here is proof that INOI coordinators specifically made sure that Ram would get in:

This is arjun arul

Some fun facts about INOI 2019:

The cutoff for class 12 was 39

The cutoff for 11 was 33

for 10 it was 29

for 9 and below it was 26

Even the sum of all these cutoffs is less than the class 12 cutoff last year!

Is it fair to allow people who submitted bruteforce solutions into camp? Does this happen in your country too?

Who is Ram and what makes you think they want him to qualify so badly?

      I guess you need to set new goals for your professional career and move on. Don't spend the rest of your life feeling sorry for yourself.

NOTE: writing from anonymous account as I don't want to get in any sort of trouble.

An important rule people must be made aware of before making opinions based on this post: [Link to file with testdata provided]"This contains the 'Live testdata', which is the testdata which will be used to evaluate your submission when you submit online during the contest. So this zip file is provided to you only as a backup for you to test against, if there are some connectivity issues. If everything is fine, you can ignore this and just submit online. Note however that after the contest ends, your submissions will be re-evaluated on more testdata."

Places where the OP misleads:

  1. The screenshot above is being posted out of context. Udit was adamant right after the contest that Ram shouldn't qualify as it might affect his own qualification to IOI. Arjun was just teasing him, full conversation: "
    Kunal Jain: @Arjun Arul will there be class wise cut off even if majority of top scorers are already from 10th and 11th?
    Udit Sanghi: maybe low cutoff for 9th?
    Udit Sanghi: ^^ I'm not saying u should do this
    Udit Sanghi: ^^ I'm saying @Arjun Arul might
    Arjun Arul: Don't you mean a higher cut-off for 9th and 10th?
    Arjun Arul: Anything to keep udit away.
    Anay Karnik: cut off 201 for 10th?
    Arjun Arul: Sounds about right.
    Kunal Jain: @Mohammad Zaid also removed then xD
    Shashwat Chandra: better to have region wise cutoff
    Shashwat Chandra: 201 for UP
    Udit Sanghi: @Arjun Arul r there chances that 12th cutoff can be <= 39?
    Rajarshi Basu: ahem
    Arjun Arul: Anything to get ram in.
    "
    2. No one knows if anything was done specifically to get anyone qualified or disqualified. Atleast post it as a possibility rather than a conclusion
    3. The sums of cut off is actually more than cut off for class 12th last year but even that is totally irrelevant to anything in the world as the problemset this year was way harder than it was last year!
    4. If the OP's code fails on 1 case, there is a good probability that it fails on many but the organizers didn't bother coming up with them because it would have been a futile exercise.

Places where I personally see an issue:

  1. Normally, the organizers are lenient with time limits and edge cases, they weren't this time. That does look suspicious but it's still dumb to draw conclusions from it.

  2. Link to problem. The organizers did not add even a single test in the live test data with L>N. Many people did not notice this and had their solutions failed afterwards. While the candidate still remains at fault here, the weak test data could have been avoided too. Just in case you thing my opinion is biased, I did not suffer from this issue but still believe it was an unnecessary hack that could have been easily avoided.

    last year there was 1 simple dfs and 1 trivial dp. This year was a lot harder

    No

    if you don't mind me asking, how much did you get? 200? or less than 100?

      "The rumours on the google sheet was proven to be correct! ", "everything in this post is a possibility"

      Contradictory statements. The first statement is drawing conclusions, not stating a possibility.

      "last year there was 1 simple dfs and 1 trivial dp. This year was a lot harder"

      Agreed, so what? When did they tell you to expect the same difficulty and no change in pattern? Also, saying this years problem were a lot harder justifies cut off to be 39 without any personal agenda in the background.

      "No"

      Arrogance. While there is a possibility that your code fails on only 1 case, the possibility of it failing on many is substantially larger.

      "if you don't mind me asking, how much did you get? 200? or less than 100?"

      Irrelevant to the discussion.

        because I think its true. I don't care about what you think.

        "Agreed, so what? When did they tell you to expect the same difficulty and no change in pattern? Also, saying this years problem were a lot harder justifies cut off to be 39 without any personal agenda in the background."

        No I am saying that this year was easier. Again, T1duS would agree with me I think

        "Arrogance. While there is a possibility that your code fails on only 1 case, the possibility of it failing on many is substantially larger."

        and what if I were to tell you that I actually got 200?

        "Irrelevant to the discussion."

        You'll be relevant once you get a full score in INOI

          "because I think its true. I don't care about what you think."

          Kindly present it as it is and not a fact. Just because you think something to be true doesn't make it true.

          "No I am saying that this year was easier."

          Difficulty of a paper is not decided by the opinions of the few but the general trend of results. As you beloved google sheets will indicate, this years paper was infact harder.

          "and what if I were to tell you that I actually got 200?"

          It would prove that being sharp in CP doesn't make a person smart as what have posted and are continually speaking is objectively very very stupid and shortsighted.

          "You'll be relevant once you get a full score in INOI"

          Doesn't deserve a response.

          PS. Seeing Arjun's comment below, it's not hard to believe now that India can't produce a gold medalist since this is how even its best and long time trainers are treated by whiners who are dismayed at someone else's qualification.

            ok Kunal

            "Difficulty of a paper is not decided by the opinions of the few but the general trend of results. As you beloved google sheets will indicate, this years paper was infact harder"

            No, this year the candidates were worse than last year. Ask anyone who got 200 about the difficulty of the paper. Except for a few participants who were expected to do well(Ram,Nishkarsh) everyone who was expecting to qualify qualified. Don't project your 121 as the exam being harder than last year

            "It would prove that being sharp in CP doesn't make a person smart as what have posted and are continually speaking is objectively very very stupid and shortsighted."

            "PS. Seeing Arjun's comment below, it's not hard to believe now that India can't produce a gold medalist since this is how even its best and long time trainers are treated by whiners who are dismayed at someone else's qualification."

            India can't produce a gold medalist because of the quality of questions set at camp(at least in 2018)

            Rajarshi and Nalin definitely deserved to be in the team last year. Why didn't they qualify?

            If this years problems are proper OI styled problems I can confidently assure you that Adhyyan, Rajarshi and Udit should be in the team

              I accept that Adhyyan ,Rajarshi,Udit are potential competitors for team but IOI needs good amount of maths as far as I know.so I expect people with mathematical background(like pranjal Srivastava) might have a better advantage.And TST is 3 months away so I expect People who aim at camp will give a proper competition so I expect it to be competition between all people who got 100+ and ram so some 10 people for 4 slots.

                I decided to delete that comment because I realized that even after being repeatedly mentioned, getting into an argument with unrated accounts is a wastage of time and energy and this whole thing, to supposedly quote myself, "Doesn't deserve a response."

                Also, it kind of beats the point of calling someone a coward when you do it from an unrated account :)

In my country there are 2 groups for grade [10-12] and for juniors. Invitations are sent for top x from first group and top y from second group.

If the motive was to get under my skin, congrats. You've passed with flying colours.

The set of files with L > N was missed out while uploading the live data, and that's my mistake. I apologize for that. But it is clearly mentioned in several places on the contest page that extra test files will be added later, as has been the practice for the last few years.

It's interesting to note that none of the participants with 39 during the contest had their scores reduced while rejudging. Bad luck with your choice of background story, I guess. But great work on taking an obvious joke out of context.

    That is all I ever wanted :*

    On a more serious note, I made this post because I was pissed about you(IARCS? Codechef?) keeping such a low cutoff. I don't know your ulterior motives, but from the eyes of almost all candidates, it seems as if you did this to let Ram through

    Maybe if I focused on subtasks instead of a full score I might've met you at camp :(

    Good luck anyhow
