Codeforces: acm.sgu.ru comes back
By kuviman, 7 years ago, translation, In English

acmsguru

Hello everyone!

acm.sgu.ru was created ~16 years ago by programming contests participants from Saratov university: MikeMirzayanov and AndrewLazarev. Today its codebase and infrastructure are completely outdated, and supporting it is unreasonably hard. Nonetheless, Codeforces team is regularly asked to revive acmsguru, since there is still a lot of interest in the problemset.

Here is the new functionality in Codeforces — additional section "acmsguru" in Problemset. All the problems from the old system are moved there. There are still a few things to do here: correctly port interactive problems, improve looks of statements, support the new section in Codeforces API, support adding these problems to mashups.

Anyway, you can solve the problems already, and view progress on separate standings page for acmsguru.

To save the spirit of acmsguru, viewing sources of other participants is disabled.

UPD: In some old problems checkers are compiled into 16-bit executables, so testing of these problems is temporarily not working.

      I wish if one problem is already accepted, then we can read the better code.

why so many "Denial of judgement"? I wanna test the code that I submit in sgu, and I got a "Denial of Judgement". Maybe it is not allowed?

    In some cases it's WA 1, not Denial of judgement (37557189 CF == 1765512 SGU)

Is there any way to view/download your own solutions on acm.sgu.ru? I couldn't figure it out.

Some links seem to be broken. For example, clicking on problems' names at submissions tab doesn't work.

That's amazing! Thanks a lot for this!

It was my favorite online judge when I was actively participating in ACM ICPC. Glad that now more people will be able to enjoy these problems.

By the way, is it possible to somehow get the archive of my solutions from acm.sgu.ru (given id and password)?

Some problems have TL = 0.25 sec, and the execution time is doubled. It's impossible to solve such problems in Java (e.g. 229 which I have accepted on acm.sgu.ru)

Problem 214 seems broken. Both xiaowuc1 and I got "Denial of judgement". I got AC on SGU and on ASC 03 in CF gym.

    It's one kind of problemset.You can develop your skill very much,b coz you cannot see others solution here,and tutorial is banned for acmsguru.To develop yourself,you should practice the problems from problemset,acmsguru and contest page

    If you want the editorial, solve problems from the main problemset.

What actual memory limits for acmsguru problems? I've got AC for problem 122 with submission which used 6200KB memory, although in statement said that memory limit is 4096 KB.

Would it be possible to restore old acm.sgu.ru accounts' list of solved problems? I did some problems in the old site but I don't know which ones are left now.
