The MO Contest Environment a.k.a. MO-Eval is a simple system for conducting programming competitions similar to the International Olympiad in Informatics – a contest where the participants solve programming tasks, which are then evaluated off-line after the end of the competition. It's built in a modular way, so extending to other types of programming contests (e.g., to on-line contests like the ACM ICPC) should be pretty easy, but it hasn't been done yet.
We use this environment at the Czech Olympiad in programming (officially a part of the Mathematical Olympiad) since 2002 and also at the CPSPC (Czech-Polish-Slovak Preparation Camp) when it's held in the Czech Republic.
You can download the current release eval-1.0 or browse the archive of past releases.
Everything is also available in my FTP archive.
The environment runs under Linux on the i386 architecture. We currently use a slightly modified installation of Debian GNU/Linux, but it will happily work with any other Linux distribution with a 2.4 or newer kernel. The only dependecies on Linux and on i386 are in the sandbox module; porting to other architectures requires just minor changes, porting to other UNIX systems is probably hard. Outside of that, everything should run happily on almost any system providing a reasonable set of GNU utilities (especially bash) and Perl. Porting to Windows is probably out of question.
MO-Eval has been written by Martin Mares. Great thanks go to Jan Kara and Milan Straka for their help and for many fine ideas.
