Dear IOI Community,

The Call for Tasks for the International Olympiad in Informatics (IOI) 2025 is now open. IOI is the most prestigious programming contest for pre-university students. The Scientific Committees of IOI 2025 invite everyone (other than potential IOI 2025 contestants) to submit their tasks to the IOI 2025 Call for Tasks. We welcome any tasks of various difficulty levels, and we are actively encouraging submissions of easy problems. The deadline for the call for tasks is (UPDATED) 18 January 2025.

The link for the call for tasks is: https://ioi2025.bo/call-for-tasks.html

For any questions please reach out to [email protected].

Best Regards,

Agustín Santiago Gutiérrez

ISC Chair

UPDATE: The call for tasks for the IOI 2025 has been extended to 18 January 2025. We have received great tasks from the community but still need more. IOI 2025 needs tasks of different difficulties so we encourage all to submit tasks of any difficulty.
