Call for tasks

Dear IOI Colleagues,

   on behalf of the IOI 2020 host, I would like to announce that the call for tasks for IOI 2020 is now open and we are inviting the IOI community to submit your tasks for the IOI.

More details about the call for tasks can be found at  https://ioi2020.sg/call-for-tasks/ and the deadline for submission is 15 December 2019.

The authors of the tasks selected for the short-list will be invited to attend IOI 2020 in Singapore as Invited Guests (authors will be responsible for their travel, but IOI 2020 will cover their stay). They will also be recognized by listing their name, affiliation and country on the official IOI website.

Please share this message also through your local communities.

Thank you and we look forward to receiving interesting tasks from you!
