The Asia-Pacific Informatics Olympiad (APIO) is an online IOI-like contest for the Asian and Western Pacific region. APIO 2021 will be held on Saturday, 22 May 2021 to Sunday, 23 May 2021. The host of the APIO 2021 invites everyone in the programming contests community to submit tasks for the APIO 2021 competition. Guidelines for tasks and instructions for submission are given below.
APIO tasks are basically similar to the tasks in International Olympiad in Informatics, which are typically focused on the design of efficient, correct algorithms. Input and output are to be kept as simple as possible. The submission of novel tasks types not yet seen in any recent programming contests is encouraged. The guidelines of task preparations of IOI should be considered, with no restriction. The documents about submission of IOI tasks, which can be used as reference to create the tasks, can be found on the IOI website.
To ensure a fair and interesting competition for all, tasks should satisfy the following conditions:
A task submission must contain:
It is also strongly recommended to contain:
Any comments related to the task are also welcome and would be highly appreciated.
Submitted tasks must be kept in strict confidence until the end of APIO 2021.
Please note that all material submitted becomes the property of the APIO community, and that by submitting the author is assigning the Copyright and all rights to the submitted materials to the APIO community.
Note that we do not wish to forbid authors of submitted tasks to be involved in other competitions and training, but we do ask them to take all necessary precautions to safeguard confidentiality.
Submitted tasks, including the description and test cases, may be subject to modifications by the organizing committee.
Task materials must be placed together in a single file (use .zip or .tgz for multiple files). Email to firstname.lastname@example.org with [Task Submission] - <task title> as the subject and attach the task submission.
Tasks that are not used will be kept secret, and will be returned to their submitters so that they can be used elsewhere. Note that all submitted tasks will be seen only by the host organizing committee, and the shortlisted tasks will be seen by all heads of delegations from the region. Communications among heads of delegations and hosts about the APIO tasks should be done mainly by e-mail and secured web.
All submitted tasks will be shortlisted by the host of APIO 2021. Then, the shortlisted tasks are distributed to all heads of delegations. If any countries need to translate the task scripts to their languages, the translated script must be submitted to the host up to three days before the competition day.
At various moments during the preparation of the APIO 2021 competition, it is possible that submitted tasks are dropped from further consideration. However, it may still be necessary to revert such decisions later. In general, all submitted tasks, whether dropped or not, should be kept secret until the end of competition.
Authors of submitted tasks will be recognized on the APIO 2021 website by listing their name, affiliation, and country (unless they specifically decline this).
