    I had my suspicions about his performances in recent Repovive contests, and there were a few signs, but they were too inconclusive to justify a ban. You can’t ban someone based on evidence that leaves you 50/50. He also won a gold medal at IOI 2026. I’m not sure how we should handle cases like this. Requiring screencasts might help, but people could still cheat while recording. At best, it would make blatant copying and pasting easier to catch.

      For the record, I don't claim anything (the comment I linked was "How" and not the one under it), I won't be surprised if k1r1t0 is honest but I'm not trying to catch him or anything

      This is really same story as in chess and it's kind of disgusting it is like this. At this point the threshold between losing 100 points and getting 100 points is just the butt plug giving you a hint that the problem is solvable in a particular way. Screencast solves literally nothing, just having some AI automation give you tags of the problem (i.e. this problem is solvable with BFS + dijkstra) on a second laptop that's invisible on the screencast is insane amount of help to high level competitors that won't allow you to detect it anyhow

      There is virtually no solution to this at the high level. At lower levels it is detectable via "expected performance doesn't match the reality", but there's nothing you can do for online apart from asking for community to keep the integrity of the competition, I'd argue that trying to do anything over that would be just harmful to the community as a whole.

          u are right up to a certain point that it doesn't mean they will never cheat forever, but it furthermore doesn't mean someone can become an LGM just by cheating

Before 1,2,10 places streak you had like 5 rounds with places outside of top100. In those rounds, were you focused the same as in the last 3 rounds, or you didn't care?

            np, [:heart:]

            my ques was

            what changes did u made in your training , and what training did u do to become lgm (reference: ur blog in which u were asking others for secret chinese sites)

            which platform did u found best for training, like ojuz,cf,atc or whatever

            well i am majorly training for olys, and i usually can solve till 1700s, for ioi specific training which platform should i use? idk why but cses,cf,atc feels nothing like oi kinda problems

            thanks!

              For ioi you can solve all IOI, CEOI, APIO, BOI, JOI, JOISC, JIOC, USACO that have subtasks >=2011

              1. Usaco Bronze

              2. Usaco Silver-COCI(a-b),JOI(a-b)

              3. Usaco Gold-COCI(c-e)-JOI(c)-JOIOC?

              4. Usaco Platinum-JOI(d-e)-JOIOC-JOISC-APIO-BOI-CEOI-IOI

              In all ranks there are problems that are difficult (bronze USACO)

                  I can't recommend anything other than what the dude above already recommended :D

                  If even simple problems on international competitions feel very difficult, you should focus not on OI skill, but on general problem-solving skill. Solve codeforces and atcoder problems, run some virtual contests. That's really the best way to get good when you are low level.

such a rise in the last four contests ? I mean when someone at a low level cheats the curve looks exactly like this one. I am not saying that he cheated but the curve is very very suspicious. It is like today I am a newbie and by the next four contests I became an expert. That is very very very rare. Also today's solve of F was very suspicious. Nobody was able to solve except for him. So yeah that says a lot (again not saying with certainty that he cheated)

      bro i am talking after the ai apocalypse. of course there are many people especially famous lgms (example tourist, jiangly and many more) who had a steady rise. but in today a rise like that? that too in less than one month? come on you know what I am talking about. when something just does not seem right people can understand it bro. maybe not like those brain rot llm users but you definitely cooked something that any sensible person can tell.

Congrats! The plot indeed seems confusing, but imho he didn't cheat. Random thoughts:

  • cases like this happen occasionally (eg Linsanity)
  • I know him quite well as an honest person, and he has the personality of always underperforming, which magnifies the effect. You all know that friend who never does well under pressure, but is incredibly smart -- that is k1r1t0. Honestly, he should've gotten that LGM title way earlier.
  • I hope he won't let the hate disturb him. A problem with most solutions like "do the next round on camera" is that the exact reason he might fail is the pressure he has. I hope he won't and this experience will make him stronger, but that is a possibility.
  • this might be a complex case forever, and you're never sure what in one's mind ( https://en.wikipedia.org/wiki/You_Can_See_Everything ), but knowing him, he's a normal dude who finally happened to control his emotions... and got a little lucky :)
  • just look at his grind in the last month!

theoretically, if you participate in div $$$1s$$$ in $$$2026$$$, the cheating is so rampant that cheating just a little bit would make your rating a bit more true to your ability than not cheating at all. and anyone can look at this guy's graph and see that he (very likely) didn't cheat up until these past $$$3$$$ contests, so he had already banked a lot of "cheating just a little each contest", and he just spent most, maybe even all of it these past $$$3$$$ contests. so this should really only be a problem if he continues to have similar performances going forward.

Since this is an AMA blog, please allow me, one of your biggest fans, to ask a few questions. Feel free to skip any that you find offensive, too personal, or just weird.

  • Please respond to this audacious comment under your previous blog post.
  • Who cares? K1r1t0 when?
  • How do you usually practice? What kinds of problems do you solve?
  • How do you typically approach to a problem? What do you do when you get stuck?
  • How strong is your mathematical background? Do you have any experience with MO?
  • What advice would you give to people aiming for GM, IGM, and LGM, respectively?
  • bashkort mentioned that you sometimes underperform under pressure. Could you elaborate more on what exactly happens in those situations (one of my friend would vomit when he is under pressure)? Have you tried to improve in this regard?
  • Why did you choose the handle k1r1t0? Is it a reference to the legendary swordmaster Kirito?
  • What do you think your chances are of winning IOI next year?

Wish you the best!

    Thank you for your questions!

    I usually don't upsolve much and do a lot of virtuals — one or two virtuals a day, usually some ICPC competitions like Universal Cup or ARC/AGC/CF Div1. At the same time, I keep at least a few difficult problems at the back of my mind. Though I only mindsolve them, since I don't like coding at all lol. This approach makes it easier to continue even when I lack the motivation to, and helps to keep my mind busy during tedious mindless jobs.

    Well, how to approach problems is a well-discussed matter, and like everyone else, I don't really know the answer. When there's no obvious way to move forward, what I try to do is to play around, have some fun with the problem — random observations can give you a lot of intuition about the problem's structure. But honestly most problems are just combinations of well-known concepts, that's why upsolving, for example, helps — you get to know them.

    I don't have much MO experience. I wanted to take part in local math competitions and maybe go to the IMO eventually, but in Belarus you can't participate in the final stages of two different olympiads, and I don't want to lose my IOI attempt for a chance. But I adore math. My whole YouTube feed is math videos lol. In the last year I started to dive into math more, finally learning a lot of high level concepts that scared me before. Actually, problems from Universal Cup led me to this. I love combinatorics, and Universal Cup has a lot of difficult combinatorics problems, which require some advanced knowledge. Eventually, I went beyond what's usually required, but it's competitive programming that gave me the motivation to learn math, even though I was fascinated by it my whole life.

    To those who want to get better I can advise to solve problems. You don't have much of a choice :D

    When I feel pressure, my head starts to fill with thoughts about anything but the contest. Body starts shaking, brain stops braining, etc... I have two IOI bronzes and only this year I got a gold medal, even though (IMO) I could already get gold two years ago. First two times I had a mindset of only letting myself be the best of the best, and the third time I finally let myself have fun! Actually, I went to a therapist and one of main things we discussed was my contest performance when I feel nervous. She helped me realize that my results don't define my worth. I believe it helped a lot.

    A few years ago I wanted to find a new nickname for myself, preferably similar to my name. I watched SAO back then and realized that main character's nickname sounds exactly like my name (kirill), so I decided to take it, lol. It's funny that his name is similar to his nickname too.

    Well, I've had a lot of ups and downs over the years, so I won't be delusional and say I'm sure I will win or even get a high place. Who knows what will be with my mental health in a year. Maybe something dumb will get in my head and instead of solving problems I will be thinking about something entirely else. Even though I'm not sure, I believe that there's high potential to get a good place. I can definitely win IOI in my best form.

      I feel like your strategy of having fun only worked out when you became skilled enough to not get stuck on any problem (so you get close to AK). Do you think this is true? I personally just lose all my motivation when I ger stuck on a problem or have bugs.

      Edit, second question: Can you recommend some combinatorics books (I know about Enumerative Combinatorics, Genfunctionology)?

      Edit, third question: Can you recommend some math channels (I have a list I prepared for other people here)?

        Maybe, maybe not, who knows.

        Idk I don't read books. I mean, I have Concrete Mathematics and The Art of Computer Programming 4A at home, but I didn't read them cover to cover.

        Uhhhh I don't think I have any non-famous math channels in mind.

  1. What's something you've felt for a long time but have never really known how to put into words, even to the people closest to you?

  2. Are you more afraid of people misunderstanding who you are, or of them understanding you completely and still not accepting you?

  3. When was the last time you felt genuinely understood by someone, without having to explain yourself, justify your feelings, or pretend to be okay?

  • Out of all the problems you've ever solved, which one do you consider an absolute masterpiece?
  • What was the hardest topic you had to master to perform well at the IOI?
  • What is your favorite topic in CP?
  • What's your take on "quality vs. quantity" in practice? Is it better to spend hours on a single super-hard problem or solve several moderately hard problems instead?
  • I noticed you changed your pfp recently, does it have any special meaning or connection to you reaching LGM?

    Just a month ago I would say that I don't have a favourite problem, but now I have it! It's this one. It's quite obvious that the statement is back engineered from the solution, but I still love it!

    I don't remember any. IOI doesn't require any difficult topics, you are gonna be fine even if you only know binary search.

    Combinatorics.

    I think quantity is way more important. For me, the main thing that practice gives is new ideas and tricks I've never seen before. So more problems is better.

    I had an idea of changing pfp's eyes to the color of my current rank. I am LGM, so the eyes are now black :D

      Yes, the statement is almost back engineered. Happy to see that you liked it!

Just because someone accomplished something you guys can't achieve in your entire lifetimes doesn't mean he cheated. He isn't afraid of losing his rating, unlike most of you. Don't be dickheads—congratulate him on his massive achievement!

So why did you get out of the top 200 for a bit round, and how could you get to the top 10 for a little time. I just mean that if you were a cheater or not, such a situations like this is uncommon.
As you can see, I'd ever been stuck and then for a few but >1 round to perform better,and after it return a bit,I want to know that if you know why did it appear.

    Hmmmm I'm not sure. I think it's a combination of me finally fixing my mindset and starting training after IOI again (I didn't do much until October lol)

First of all, Many Congratulations!!

Question :

When you are thinking about the problems (mindsolving) while doing something else, how does it look like, can you think on a problem with focus while doing some other (brainless) job? I feel it's hard for me to focus on a problem if I am not already thinking for around 5-10 minutes, like won't your attention get disturbed and then your brain will have to get back to focus mode again? If you have some other thoughts on mindsolving (like what type of imagery do you create in your mind), please do share. I understand that it can be very difficult to explain such a process.

Comment :

I imagine how hard would it be for you to face those comments after doing sooo much hard work, I really wish that you can ignore them or accept them and be able to keep doing the same hard work without it affecting you.

Even from a very rational point of view, I don't think anybody should be accused of something like this, like if there's actually someone who's like a prodigy and who's making higher jumps, he/she should not be discouraged just because it does not look normal. That's like killing a new tourist at his birth. So, even if people have doubts they should keep them to themselves.
