The Asia-Pacific Informatics Olympiad (APIO) 2025 is just around the corner — scheduled for May 17th and 18th, and will be hosted by Uzbekistan.

For those who haven’t heard of it, APIO is a prestigious IOI-style online contest featuring 3 challenging tasks over 5 hours. It's an important part of the IOI team selection process for many countries across the Asia-Pacific region. More info is available at https://apio2025.uz/.

Feel free to use the comments to discuss problem ideas, scores, cutoffs, and results after the contest (and any mirror, if there is one) wraps up.

Good luck to everyone participating — hope it’s a fun and insightful contest!

Hola CP-igos!

As the name suggests yet another blog an AI, cheaters etc.

Introduction

Flashback to 1.5 years back... I just joined Codeforces, all contests were fine, no cheater blogs(and no cheaters)... I used to spend some time reading interesting blogs in catalog and the "Recent Actions" where I used to find blogs on other "non-educational" blogs, be it somebody's productivity plan, somebody reached GM, some new solutions on rounds, the "if u comment under this blog" blogs etc. All this was fun.. I could spend an hour or so, reading all this and the comments underneath them

The Issue

Fastforward to now.... A round gets over.. And soon by the next day, all we have is tons of blogs on cheaters doing this, cheaters doing that, I found this, I found that and what not. And then people finding underneath blogs, seperate blogs being made for seperate cheaters, as though the cheaters have become kings, every set of cheaters with the same solution gets a seperate blog dedicated to them. Gone all the useful blogs, and all for sometime, drowned... Plus mood getting spoilt

Personally I do not know anybody who likes this, this becomes downright irritating.

Suggestion to Sort it Out

Suggestion 1

For every round we have testers who test the rounds.. we can also have testers who are proficient with AI to make the problems AI-safe. Manually checking for variable names won't last long.. Cheaters are also learning, soon the techniques used to detect cheating like "tons of comments in code", "similar variable names" etc. wont be a problem for the cheaters, they will start removing the comments, start giving weird variable names and so on. So eventually if we need to stop this for once and for all, we should have AI testers.

Suggestion 2

To all those who are still interested in detecting post-round cheaters can still post comments, but we have a separate blog made (preferably by the maker of the round), named "Round XYZ : Cheating Analysis" or "Cheating Reports"(or a better name, acutally a better name would be better I dont really like this name) as made by chromate00 like Anti LLM Evaluation Report, where the problem setters can actually inform the participants about the cheatings caught etc. And we can have comments under the blog regarding the cheating suspects they have(preferably in bold, because it might get drowned)

Well this is all I have to say.. If anybody thinks I might have made a mistake or you dont think my opinion is correct, anywhere please let me know. And if you have any more suggestions too!
