It would've been great to get more information about the IOI performance — especially how the 362.14 score was distributed, how the code looked, and what kind of training was put on top of o1 to produce o1-ioi (and whether that was unbiased)

Maybe I am wrong, but even with unlimited number of submissions I find gold at the IOI extremely impressive compared to 1800 on Codeforces.

This model is constrained because of the inference cost, so this rating should be viewed as lower bound of what's possible. Highly likely that iterating for longer time during reasoning is going to produce even better results. Would be fun to see an actual paper showing if it's true and if it is what are the diminishing returns related to the time spent during reasoning.

Couldn't disagree more.

There's a long history in automated theorem proving and automatic ways to solve geometry. 2D geometry in particular is very uninteresting and I don't think that it's particularly surprising that computers can solve it. I'm sure if you went through the IMOs of the past, there were tools that could solve some problems long before the OpenAI models. It is impressive that they scored 4/6, but the two they didn't solve were specifically the combinatorics ones which I would argue require more interesting argumentation rather than algebraic bashing.

For competitive programming tasks, I haven't seen anything that comes close to being coherent prior to this past year. I remember efforts to try and design such AI advertised here on CF as far as 10 years ago, but solving any IOI problem was a ridiculous idea.

Well, go try and solve them yourself. You have unlimited time to do your "algebraic bashing" in P6. If you fail, you can also try to solve number theory P2. These problems aren't as easy as you think they are

You're misinterpreting what I mean — I personally would probably struggle to get a bronze at IMO. I do not claim they are easy for a human in any way. Classical Stockfish without any neural nets could beat the world chess champion very easily. I could train for a lifetime and not be in any way close, and yet with modern computing capabilities I do not find this accomplishment of classical Stockfish to be shocking.

Similarly, while solving P2 and P6 is an amazing accomplishment for the AI, comparatively I consider the accomplishments of the o1 model in competitive programming to be more impressive as an indicator of the AIs abilities. If you had told me that some automated theorem prover had solved P6 without having anything to do with neural nets or machine learning, I'd think it's cool but I wouldn't be shocked. For competitive programming, as I said, even the simplest code generation has been atrocious prior to these latest developments.

Additionally, I also mention the combinatorics problem being failed by the AI because I find P5 to be particularly approachable. I personally believe if you gave P5 to IOI competitors, almost everyone with an IOI gold would solve it. However, being a constructive problem it seems less likely to be solved by some kind of automatic axiomatic tree derivations or repeated theorem applications.

I have to admit that the IOI allowing partial scores gives a huge advantage to the programming AI, because there really aren't "partially correct proofs" in maths, so you could use that point. However, it's pretty hard to argue about that since we don't know how "close" the math AI was to solving the remaining two problems.

In any case, comparing the relative impressiveness of accomplishments on this scale doesn't imply that any of them is easy for a human.

I'm not neglecting the difficulty of generating code or solving Informatics problems, but it's just isn't as impressive as math is. Because writing code for a given algorithm isn't an insanely hard task and modern AI can comfortably do that, and the solutions to most Informatics questions(and IOI in particular) come down to known algorithms with no new smart ideas or any creativity. I myself has witnessed students with almost no talent come through all national challenges and get a medal at IOI by just their hard work for a couple of last years, while in Maths olympiads this is almost impossible. Most difficult combinatorics tasks in most cases can only be solved by a pure talent. You are right that nowadays 2D geometry is of no interest because 1. most strong students can bash it unless it was really chosen to be unbashable, 2. geometry has became a skill that everybody just trains through the years regardless of their aptitude. New discoveries in maths often happen not when somebody finds a topic no one has discussed for several centuries, but when an inside genius of somebody starts glowing and their is an eureka. And in hard olympiad problems(like P6) you also need to think of a smart cunning way to use what you have. The only difference is that you are not the first one to discover this way. Finally, currently it is nearly impossible to make AI's to invent something they have never heard of(such as ideas of the solution of P6). Of course, if you have a functional equation, you can try to "algebraicly bash" it by making a billion of substitutions and praying it will help. But if it is P6, it won't.

This is an insane statement.

You clearly have some bias towards math, which in my opinion is very unfounded. The overlap in the way of thinking for IOI and IMO is quite large, and problems like P5 in IMO 2024 could easily appear in IOI under some modified form.

Perhaps you're not familiar enough with the level of IOI problems, but to say they "come down to known algorithms" is just comical. Sure, it is not uncommon for the final solution to a problem to involve some well-known data structures or some well-known algorithm, but that's not what solving a problem is. The observations required to design a correct algorithm is what the solving consists of, and those observations require very much the same ingenuity that a math competitor uses when making observations about the structure of a math problem. Saying that an IOI problem uses known algorithms is like saying that an IMO problem relies on known theorems and definitions. It is true, but that's not relevant to the actual interesting part of the problem-solving process.

Yes, it's impressive (although I'm not sure whether it has access to the editorials).

I gave it five 1600-rated problems (2004D, 1996E, 1994C, 1985G, 1980E), and it solved three out of the five (submission links: 2004D, 1996E, 1985G) in one try (after using C++).

Here's the conversation link

I tried AtCoder, here's the conversation (this link doesn't seem to work now somehow, I might change it in the future if this becomes an issue).

I gave it 3 1200-rated problems (ABC361D, ABC361E, ABC362E), 2 1300-rated (ABC363E, ABC367E), and 1 1500-rated (ABC367F). It solved all but ABC361D.

Interestingly enough, it solved both E and F in ABC367. If it also successfully solved A-D, with a fast enough speed, it could've reached a 2400-performance (equivalent to approximately 2526 on Codeforces). AtCoder has policies against the use of AI, but it might not be that easy to detect.

AtCoder problems have a significantly different style from Codeforces (and I feel that GPT o1-mini is better in AtCoder). Let me know if you want me to test a specific website.

Please try ARC instead, ABC is a meme and well known to have only standard problems

Some of my friends did try, it can solve some problems in range 500 — 1000 and fail some problems in that range too (infact it failed a 500 too). The rating refers to the kenkoo rating

My main takeaways :

1) it can solve standard problems. Not surprised, and somewhat even a good thing. Now contest authors can no longer put them on contests which is a plus

2) it can solve most d2AB level non standard problems. Slightly sad but maybe the meta can evolve.

3) ABC, Div3 and Div4 cant continue in the way they currently are without significantly disadvantaging the people who dont have access to o1 mini. Further, maybe some extra care is needed in selecting d2Bs

Multistep problems will always be an issue for it, and we should aim to have more such problems.

As for future improvements, it will definitely get somewhat better. But i dont think this particular type of AI can become a grandmaster lets say (not that no AI can reach, but this type of bruteforcing solutions cant). This is because of how the AI works.

I dont believe this type of "generating 1000 solutions and then trying to narrow down to 10 possibilities" will work for harder problems because they need multiple reasoning steps i.e. your probability of correctness exponentially decreases

Thanks for the test C0DET1GER! I suppose it would also be interesting to test it on live contests, to make sure that it is not a overfitting of existing data the model was trained on (but I find this unlikely).

Also, my hypothesis is that the model probably performs better in atcoder because the statements are more direct.

I’m curious to explore how much it can benefit even more advanced contestants. It could potentially help as a good way to search for classic subproblems or maybe help as an implementation assisntant.

This is crazy. Maybe the end of online competitive programming era.

Some users may argue this is not a big deal, using GO as example. In the Go game, the AI beat world rank 1 player Jie Ke very hard in 2017, does Go die? No, because in the real competition, players cannot use AI.

However, in codeforces, all players are competing online without monitoring, which means you don't know if he or she is cheating or use AI. Imagine you are an expert, in a div2 round, you solve 2A and 2B in 15 minutes. Then you discover that you have already rank 10000+, because many many newbies just copy the problem statement, paste to chatGPT and solved up to 2D, both 2C and 2D has 10000+ accepted users. How do you feel?

It just like you are top runners in Marathon race, many cheaters just ride the motorcycle to finish the race in 30 minutes, break the world record, and the committee just say their result is effective, you rank behind them.

I can solve the problems just for fun, but cheaters will not. And it is not fun if cheaters beat me every time I participate, and make my rating drop from master to newbie.

It's time for codeforces official to do something do handle this situation. I am serious.

While I agree with the general sentiment, isn't this similar to the situation with online strategy games like chess? Any player can quite easily cheat. All it takes is using a few engine moves when needed, looking at opening prep, or even just having access to the computer evaluation. You could even argue that as chess computers have gotten better, online cheating hasn't increased by all that much (I'm not sure if there are statistics that disprove this).

The main reason is that everyone knows you can cheat on chess.com or lichess. Your chess.com rating and your lichess rating hold very little value. There is not that much of an incentive to cheat because there isn't that much value to the rating itself.

With that being said, I just realized that there is a concrete difference between chess and CP. With chess, there are a lot of official FIDE tournaments where your rating actually matters. There isn't really an equivalent for CP. The only equivalents are in-person contests like ICPC and IOI which are pretty hard to go to or compete and are restricted to specific age brackets.

I totally agree with you with the last paragraph.

You know in leetcode contest, the cheating is much more severe. Because some of the recruiters in some country, they know leetcode, and if you get a high rank in leetcode, for example, guardian badge, you will be more likely to pass the resume screening. For chess, even if you get very high ranking, you will not get a job for it.

And the in-person contests for programming is very sparse, and there is no contest for people that are already at work. Nearly all contests are for high school (IOI) or undergraduate (ICPC), if you pass the era, you can only participate Meta Hacker Cup for fun. Really hope if there is in person contest available in the future, especially for all ages.

It is definitely overhyped, but I wouldn't be calling it a web scrapper either.
There is some merit to it.

Imagine if you compress and organise the problems in a nice coherent structure.
What that will allow you to do is to effectively query that database and find the answers faster than you would otherwise.
Basically, I would say that it is like a binary search in a sorted array, compared to a linear search in a randomised array.

Google already does it with their search engine, but I would argue GPT search is a one step further in terms of finding of what you need.
Roughly the difference is the same as between syntactic and semantic search.
In syntactic search you try to find a substring "search term" in the text of a webpage, but with a semantic search you would also consider the meaning of a "search term", not just a substring entry.
Google already does semantic search, but it is just an example to make a point.

For each problem, our system sampled many candidate submissions and submitted 50 of them based on a test-time selection strategy. Submissions were selected based on performance on the IOI public test cases, model-generated test cases, and a learned scoring function. If we had instead submitted at random, we would have only scored 156 points on average, suggesting that this strategy was worth nearly 60 points under competition constraints.

No, it means it generated a bajillion different codes by itself and then took the best 50, similar to what alphacode did.

Ah, candidate here refers to code it generated. Got it. Somehow my head interpreted that as IOI medal candidates for some reason. Thanks for the help.

By candidate submissions, it doesnt mean other participant's submissions, rather potential solutions generated by itself

As far as I know atcoder does not allow LLM solution and consider it cheating. I have never use gpt or anything in a contest . Can anyone tell me if it is ok to try those LLM for codeforces and meta hacker cup for solutin ideas ???

I played with ChatGPT o1-preview model for about a day and I was almost immediately disillusioned.

It is good with easy problems and struggles a lot starting with Div1A.
The model doesn't demonstrate a capability of "understanding", at least I didn't get that sense from it.
It still does rookie mistakes, creates unused variables, writes comments that don't match the code, etc.
Still far far away from "AI will take your job" =)

Have you tried the o1-mini model? It seems to be much stronger at thinking than o1-preview.

→ Ответить

Not yet.
I was assuming o1-preview is stronger.
Probably I am wrong.
Will try it out.
Thanks for suggestion!

lol dude u can't even solve div1 A in 2 hours, but somehow the fact that a preview model struggles with it given just a few minutes makes you think it's far from taking away your job. idk man even 3.5 demonstrates better "capability of understanding" than your cope

We had a good thing, you stupid piece of code! We had Codeforces, we had Atcoder, we had everything we needed, and it all ran like clockwork! You could have shut your mouth, helped up code, and made as much money as you ever needed! It was perfect! But no! You just had to blow it up! You, and your pride and your ego! You just had to be the man! If you'd done your job, known your place, we'd all be fine right now!

Everyone's saying that it's gonna be the end, but we have to ask ourselves: how many people are actually dishonest? In terms of cheating in online games, I'd say not many. For example, AI can crush the best people in chess, yet most players on chess.com and lichess are honest. Furthermore, if we somehow took competitive programming out of the job application process (aka made it completely pointless to show off "Master on codeforces" on your resume), there would be much less dishonesty.

Could hiding the verdict of the solution decrease the performance of the AI?

It uses the public and self generated testcases to train so that wouldn't matter in a contest.

From reading the short blog post, I assumed it is factoring in the verdict of the solution as part of the decision making process (as that would be the smart thing to do).

But I could be wrong and it could simply be results agnostic.

Even if that is the case its always possible to just generate your own test cases.

Now I'm very curious about how AI is good at making a correct naive solution in just one try (naive solutions mean, for example, inefficient solutions like $$$O(N^2)$$$ time complexity in $$$N \leq 10^6$$$ constraints but it outputs correct answer in all testcases).

In fact, OpenAI made the following statement, and it means that AI improved its performance from the 49th-percentile to the 92nd-percentile in IOI just by increasing the number of allowed submissions from $$$50$$$ to $$$10 \ 000$$$.

With a relaxed submission constraint, we found that model performance improved significantly. When allowed 10,000 submissions per problem, the model achieved a score of 362.14 – above the gold medal threshold – even without any test-time selection strategy.

However, if we already have a confident naive solution, we can use the random generating strategy for avoiding WAs — just compare the answer in small testcases and check whether it outputs correct answers like the following code.

In my experience, this strategy can find at least $$$1$$$ counter-example in $$$>95\%$$$ of WA solutions even with testing only $$$1 \ 000$$$ random testcases below $$$N \leq 10$$$, and testing should finish in $$$0.01\mathrm{sec}$$$ on average even if the naive solution is like $$$O(2^N)$$$. It is very realistic to test all $$$10 \ 000$$$ submissions x $$$6$$$ problems in $$$10$$$ hours of contest duration. (Note that since the compilation time is long in C++, which is the only allowed programming language in IOI, we should consider another strategy just for compilation though)

int NaiveSolution(int N, int M, vector<int> A, ...) {
    // Naive program written by AI
}

int CorrectSolution(int N, int M, vector<int> A, ...) {
    // Program candidate written by AI
}

int main() {
    for (int t = 1; t <= 1000; t++) {
        // randomly generate a small test data
        int Ans1 = NaiveSolution(...);
        int Ans2 = CorrectSolution(...);
        if (Ans1 != Ans2) {
            cout << "The program is wrong!" << endl;
            return 0;
        }
    }
    return 0;
}

In addition, to avoid TLE, just testing the execution time in one random big testcase is enough for most of the problem, and we don't always need to test in max testcases. For example, even if the constraint is $$$N \leq 10^6$$$, testing in a $$$N = 10^4$$$ testcase should be enough for most cases, because generally, time complexity matters. For example, I think that distinguishing $$$O(N^2)$$$ solutions and $$$O(N \log N)$$$ solutions is possible in $$$N=10^4$$$ cases for $$$>80\%$$$ of the CP problems. Note that something like "it works well in $$$(N, M) = (10^4, 5 \times 10^3)$$$ testcases but works very bad in $$$(N, M) = (10^4, 1)$$$ testcases" can happen in some problems, but I think that this kind of case occurs in less than $$$20\%$$$ of the CP problems.

Therefore, now I am even starting to think about IOI-Gold AI is just around the corner, and the only remaining piece is making a confident naive solution (+ to solve some issues for a long compilation time). I really want to know how AI is good at such skills currently.

I agree with what you said. In fact, this description is very obvious. I think one could implement it in a script using the OpenAI API.

Everyone ready this comment you will definitely upvote it ! Codeforces should do partnership or deal with openAI.Before any contest begins , Codeforces will give all there questions in TEXT to those AI platform and ask them not to show or answer anything about that question while the CONTEST is running (Say 2-2.3 hours) After that you can do whatever you want chat gpt , io ,etc etc

It would be very helpful because then no one will be able to cheat during that CONTEST TIME...!

How about the following benchmark to test "reasoning" ability: test these NNs only on problems that have a tricky case. Look for recent-ish (for as long as pretests have been strong) problems which have only a few FSTs, usually due to WA. This can miss some suitable problems but it's something. If it's not enough to use what usually works on such problems or filter out nonsense using correct outputs, failure specifically on such special hard tests would suggest a lack of reasoning ability.
