Dear IOI community,

The Call for Tasks for the International Olympiad in Informatics (IOI) 2022 is now open. The Host Scientific Committee of IOI 2022 invites everyone (other than potential IOI 2022 contestants) to submit their task to the IOI 2022 Call for Tasks. We welcome any tasks of various difficulty levels.

Each submitted task should contain at least the following:

• author(s) information: name, e-mail, affiliation, country, and author's role in national olympiad;
• task statement (PDF is preferred);
• description of the desired solution.

The authors of the shortlisted (around 10) tasks will be invited to attend the IOI 2022 in Indonesia. In the case the task authors reject the invitation, or are ineligible to be invited (due to the current pandemic), they will be awarded IOI 2022 souvenirs (including, but not limited to T-shirts) by mail. Additionally, the authors of tasks included in the actual competition will also be recognised by listing their name, affiliation, and country on the official IOI website (unless they specifically decline this).

For more details (including how and where to submit the task), please check the IOI 2022 Call for Tasks page. For any questions, please reach out to hsc_at_ioi2022.id. We hope to see great tasks from the community.

Thank you,
IOI 2022 Host Scientific Committee
