History
The UVa OJ was created in 1995 by Miguel Ángel Revilla, a mathematician teaching algorithms at the University of Valladolid in Spain. Ciriaco García de Celis, an
informatics student at the University of Valladolid, implemented the first version of the judge using
Bash, and then developed and maintained it for more than eight years.
In April 1997, the judge became open to the public (not just students of the university). In November 1999 and 2000 UVa hosted the
ACM-ICPC SWERC programming contest. In July 2000, UVa Online Judge started to host training contests. By September 2007, 5.9 million programs were submitted by more than 63000 users.
In September 2007 a new system, developed by Miguel Revilla Rodríguez, was launched at a new server at the
