1. DOMjudge overview

DOMjudge is a system for running programming contests like the ACM regional and world championship programming contests.

This means that teams are on-site and have a fixed time period (mostly 5 hours) and one computer to solve a number of problems (mostly 6-10). Problems are solved by writing a program in one of the allowed languages, that reads input according to the problem input specification and writes the correct, corresponding output.

The judging is done by submitting the source code of the solution to the jury. There the jury system compiles and runs the program and compares the program output with the expected output.

This software can be used to handle the submission and judging during such contests. It also handles feedback to the teams and communication on problems (clarification requests). It has web interfaces for the jury, the teams (their submissions and clarification requests) and the public (scoreboard).

About the name and logo

The name of this judging system is inspired by a very important and well known landmark in the city of Utrecht: the dome tower, called the `Dom' in Dutch. The original logo of the 2004 Dutch Programming Championships (for which this system was originally developed) depicts a representation of the Dom in zeros and ones. We based the name and logo of DOMjudge on that.

We would like to thank Erik van Sebille, the original creator of the logo. The logo is under a GPL licence, but Erik suggested a "free as in beer" licence first: you're allowed to use it, but you owe Erik a free beer in case might you encounter him.
