IOI Server time processing

By Hasan, history, 6 years ago, In English

I was wondering how many procedures does the IOI Server processes in a second, compared to Codeforces Server and is there any reference for that?

Thanks in advance

There is nothing like "the IOI Server", testing machines are provided by each year's organiser (imagine having to ship a huge number of computers somewhere each year, replace them when they're outdated etc.), so the answer is: different number each year.

IOI tasks are set so that shouldn't matter, though.

    So if I wanted to compute the complexity of my solution, How many procedures should I consider for a second?

      I would say 10^8.

      Let's say the same number as on CF.

        I wrote a code with complexity 1e9 and it passed on codeforces (custom test) in 800-1000 ms, I guess that's a bit fast.

          I guess it had a very good constant. Try 1e9 hashset insert/delete/lookup operations, each of them has complexity O(1).
