I hope there are no stupid restrictions like "You may participate no more than X times" or "you should be under Y to be eligible".

    As far as I see the japanese website, This contest opens to only university students. But it seems that there isn't age limit or the number of times limit.

      Any update on that? To confuse more in e-mail in "eligibility" part it is also written "Must be in top 100 contestants from Qualification contests A(students living outside Japan are limited to 10), top 60 contestants from Qualification contests B(students living outside Japan are limited to 5), or top 60 contestants from Qualification contests C(students living outside Japan are limited to 5).", but few lines below rules that Um_nik mentioned are written (and I assume these are real ones and I should ignore that eligibility part).

        Here in the "Event Outline" part is some complex procedure to determine the finalists involving irrational numbers... Not sure if it is the correct one though.

          At least it is well-defined... (at least I think so)

          And I think applying the "n qualifier from a region" rule before the "top x qualifiers" rule makes sense.

Lol, registration form is terrible. It took me ages to fill it and I was thinking that question about size of my mother's shoes may pop up at any moment.

The onsite contest is not open for high school students, right?

    I was wondering the same thing. The bracket that states who is eligible is not very clear to me as I don't understand like half of the options. There was some "graduate school", and I think that the best chances for high school students would be to be part of this category. Could someone tell us?

      Grad school means PhD students.

      From the way I read it, it seems to explicitly mention only university students and above, so it implicitly forbids high school students. It doesn't make sense though.

        It doesn't make sense though.

        Why not? To me it seems like the purpose is to look for workers who are old enough to do internship or a full time.

          Over 18 is old enough. I also know people who worked (in programming) while in high school.

            But maybe it is more likely to find a university student with the right skills than a high school student?

              A high school student that reaches the finals will have the necessary skills as likely as a uni student. Those who don't reach the finals are irrelevant and it costs nothing to let them participate. Therefore, there's no reason not to let them participate.

              Your arguments are valid, but extremely weak.

                Usually "school student that reaches the finals" that has "the necessary skills as likely as a uni student" will go to university and you will not see him next 5 years.

                  Why would the organisers of a competition for university students not see university students?

                I am not sure about the programming scene in the europe, but I don't think this is true at least in (most of) south east asia. Most of the top competitive programmer I know here only know CP(or at least have minimal developing experience) during their high school.

                  Most people over here who know something from programming don't know even what CP is. However, what I'm talking about is high school students who are elite to the point of reaching top ~20 worldwide in this contest; these would probably know a lot more than just CP. How many of them are in your sample?

                  Um_nik, well I guess you are an abnormal data point? I am not saying anything is wrong, I am just guessing what the organizer think. I am sorry if I offend anyone in anyway or if my point is weak.

                  Xellos, probably 0(Sorry, my point about good Competitive programmers should not imply the top 20, my bad). But I think Um_nik have just became a sample! I think I read from quora that I_love_Tanya_Romanova does not know much about dev until recently as well. (of course they would know more than CP, but they may not have the relevant skills the organizer wants?) Just a hypothesis here.

    I think yes (last year's code festival onsite is also not open for high-school student) I guess the reason is the same as TCO's or GCJ's because onsite contest of them is not eligible for under-18. (Also I don't know Topcoder's or GCJ's reason)
    But this is so sad for thousands of people including me, and I can't participate next 3 year's onsite so I hope high-school students will become eligible.

      There are plenty of students around the world who are over 18; an age requirement has nothing to do with school.

      Also, I think TCO and GCJ are open for high school students too.

        I trusted this comment. For example, TCO is eligible for 18 years or older.

          So TCO is open to high school students who are 18 years or older. (I was 19 when graduating. I know people who were 20 when graduating, without failing a grade.)
