Competition Schedule
There will be two competition days. On each day contestants will be given three tasks to complete in 5 hours.
There will be a 2 hour Practice Competition prior to the first competition day, to familiarize all contestants with the grading system. The tasks used in the Practice Competition will be published before the IOI. Contestants may bring printed solutions to these tasks, on paper only, during the Practice Competition.
Each contestant will receive the official English version of the tasks in an envelope on each contest day. The team leaders can translate the task statements for contestants and the translated statements will be provided in the envelope with the English version. Each contestant will have online access to the official English version of the task statements and all translations in electronic format (PDF).
Each task is divided into some number of subtasks, each worth a portion of the total points. Each subtask is either a programming subtask (the solution is source code) or an output-only subtask (the solution is a set of output files).
