Abstract

The Japanese Committee for the IOI (JCIOI) had held the second-round contests of the Japanese Olympiad in Informatics (JOI) in which nearly 60 contestants participated. The JCIOI did not employ networks in the second-round contests to avoid high cost. However, contestants sometimes make simple mistakes (e.g., format errors), so the JCIOI adopted wireless networks to respond to submitted source codes in the last second-round contest. This paper describes how we built the contest environment using wireless networks. In addition, we also discuss the judging system used in the second-round and final-round contests.
