DOMjudge - Introduction

DOMjudge is an automated judge system to run programming contests. It has a mechanism to submit problem solutions, have them judged fully automatically and provides (web)interfaces for teams, the jury and the general public.

DOMjudge is meant to be used in programming contests like the ACM ICPC programming contests, where teams are on-site and there is a fixed problem set and timeframe.

Key aspects include:

• Webinterface for portability and simplicity
• Scalable: distributed judging is easy
• Modular system for plugging in languages/compilers
• Features rejudging, clarifications, detailed submission/judging info
• Lightweight, depends on standard software to do its task
• Designed with security in mind
• Compatible with ICPC Validator Standard
• It's Open Source, Free Software

It has been used in many live contests, a selection:

• Locally: Utrechts Kampioenschap Programmeren (since 2004)
• ACM ICPC Sub-regionals: BAPC (since 2004), GCPC (since 2010)
• ACM ICPC Regionals: NWERC (since 2007), SWERC (since 2008), USA-SER (since 2010)
• ACM ICPC World Finals: 2012 for ICPC Live

The presentation slides (PDF) of Tobias Werth's presentation at the 2010 ICPC World Finals show a lot of DOMjudge's features. You may also view the online demo.
