Therefore each participant registers their prepared problem and the opponent will get a list of all problems remaining for the challenge. The problems of the last selective round are then implicitly fixed.

Running a video conference with participants around the globe might come with technical difficulties. As the report is the central part of a fight, we require each participant to upload a recorded presentation at latest on July 11 (AoE) to a web space. The link to the upload space is visible to team manager on the team management page.

This means that in each room, there will be only 2 teams competing. A reporting and an opposing team. In the second stage, both teams change their roles. In the case of an odd number of teams, there will be one room with three teams, where the third team acts as observer.

The timing in each stage is as follows
