The 19th Thailand Olympiad in Informatics (Unofficial) Mirror Contest

Revision en3, by Plurm, 2023-05-24 14:51:23


I'm very happy to announce that, with the permission by the Scientific Committee of TOI19@NU, an unofficial mirror for the TOI will be hosted this May/27/2023 11:05 (Moscow time) and May/28/2023 11:05 (Moscow time), accessible at The Unofficial Mirror Contest of 19th Thailand Olympiad in Informatics Day 1 and The Unofficial Mirror Contest of 19th Thailand Olympiad in Informatics Day 2, respectively.

The tasks will be given in Thai and English languages. The scoring rule will be the IOI-style scoring (i.e., with subtasks in each of the problems). In each of the contests, you will be given 3 tasks and 4 hours to solve them.

Note that the problems will probably be easier than the IOI, as the contest is intended as a regional selection rather than a national selection.

Finally, I would like to thank the Scientific Committee of TOI 19 for the permission to reuse the problems and test data here, and also thank MikeMirzayanov for Codeforces and Polygon (which has also been used by the committee to generate test data for this contest). A feedback form will be provided after the contests end.

I hope to see you all soon and thank you for joining the mirror contest!
