Some users don't want to learn, some other simply ignore advises.
But please follow the following guideline:
To make it short: ALWAYS USE YOUR COMMON SENSE IF POSTING!
If you don't have common sense, don't post.
More specifically:
For new threads:
a) Good, meaningful title:
The title has to say what the problem is about in best way possible.
If that title occured already, it's definitely bad. And contest names aren't good either.
That's in fact a requirement for being able to search old problems.
Examples: Bad titles:
- "Hard"/"Medium"/"Easy" (if you find it so cool how hard/easy it is, tell it in the post and use a title that tells us the problem)
- "Number Theory" (hey guy, guess why this forum's named that way¿ and is it the only such problem on earth¿)
- "Fibonacci" (there are millions of Fibonacci problems out there, all posted and named the same...)
- "Chinese TST 2003" (does this say anything about the problem¿) Good titles:
- "On divisors of a³+2b³+4c³-6abc"
- "Number of solutions to x²+y²=6z²"
- "Fibonacci numbers are never squares"
b) Use search function:
Before posting a "new" problem spend at least two, better five, minutes to look if this problem was posted before. If it was, don't repost it. If you have anything important to say on topic, post it in one of the older threads.
If the thread is locked cause of this, use search function.
Update (by Amir Hossein). The best way to search for two keywords in AoPS is to input
[code]+"first keyword" +"second keyword"[/code]
so that any post containing both strings "first word" and "second form".
c) Good problem statement:
Some recent really bad post was:
[quote][/quote]
It contains no question and no answer.
If you do this, too, you are on the best way to get your thread deleted. Write everything clearly, define where your variables come from (and define the "natural" numbers if used). Additionally read your post at least twice before submitting. After you sent it, read it again and use the Edit-Button if necessary to correct errors.
For answers to already existing threads:
d) Of any interest and with content:
Don't post things that are more trivial than completely obvious. For example, if the question is to solve , do not answer with " is a solution" only. Either you post any kind of proof or at least something unexpected (like " is the smallest solution). Someone that does not see that is a solution of the above without your post is completely wrong here, this is an IMO-level forum.
Similar, posting "I have solved this problem" but not posting anything else is not welcome; it even looks that you just want to show off what a genius you are.
e) Well written and checked answers:
Like c) for new threads, check your solutions at least twice for mistakes. And after sending, read it again and use the Edit-Button if necessary to correct errors.
To repeat it: ALWAYS USE YOUR COMMON SENSE IF POSTING!
Everything definitely out of range of common sense will be locked or deleted (exept for new users having less than about 42 posts, they are newbies and need/get some time to learn).
The above rules will be applied from next monday (5. march of 2007).
Feel free to discuss on this here.

Let be a positive integer. A positive integer is called a -good number if it satisfies
the following two conditions:
1. has exactly digits in decimal representation (it cannot have leading zeros).
2. If the first digits and the last digits of are considered as two separate -digit
numbers (which may have leading zeros), the square of their sum is equal to .
For example, is a -good number because Find all -good numbers.
Given a cyclic quadrilateral ABCD inscribed in the circle (O). Let E and F be the intersections of AD with BC and AC with BD, respectively. Prove that the circle with diameter EF is orthogonal to (O).
A polynomial with degree is reflexive if there is an integer such that for every , where for . Let be an integer and be a polynomial with integer coefficients. Prove that there exist reflexive polynomials , with integer coefficients such that
no it doesnt unless it was already a leaked problem on the internet. If you give it a IMO level question you made up, small chance it is going to get it right
Bro! Are you promoting the usage of ChatGPT in mathematical olympiads? It is well known that ChatGPT often fakesolves problems! Maybe you should work on your own mathematical skills than drawing attention away from legit mathematical causes with your promotion of AI in mathematical olympiads! Stop being unethical now!

By immediately attacking me for my opinions, you have revealed your ignorance of olympiad maths. While ChatGPT and other LLMs are clearly capable of solving simple linear or quadratic equations, and basic mathematical modeling problems are no problem for it, you are ignoring that this forum is under the name 'HIGH SCHOOL OLYMPIADS', not 'MIDDLE SCHOOL MATHS'. I'm just suggesting that AI can help many people without access to mathematical resources, a good way to learn and improve, which is in no way related to the elitist olympiad mathematics. In olympiad mathematics, AI has no purpose and should never be used.

i disagree, i think limiting AI's potential to only lower level math will hinder its development anyhow.
Furthermore, just wait a few years until deepseek and gpts start acing amcs and amies
That is impossible! Imagine thinking that a language model is capable of solving mathematical problems involving complex thinking and creative methods. This is a preposterous statement that seeks to claim that AI can replace humans.
Alphageo is not ChatGPT. Alphageo mixes a specialised AI to make geometric claims with a logical proof software. Furthermore, do you really believe that Alphageo is good? Remember that Alphageo is sponsored by a massive website company called Google, which means that it will likely have biased testing results that only make Google look good. It is very likely that Google chooses several IMO problems and pretends to solve them under Alphageo.
Also, where are you getting your statistics from? How could alphaGEO solve 4 out of 6 problems when there was only 1 geometry problem? Please inform yourself of the real situation before commenting on this issue.

just wait and see
AI is going to take the world by storm in at most a year by now...
The chat gpt alreadly knows how to solve the problem of IMO USAMO and AMC?
Yes in a way, but it codes them or bashes most out for AIME and AMC. For USAMO and IMO, it knows key ideas of solution, but only the very top AI's can solve some problems that level with 7/7 solutions. But soon enough, AI will be smart enough to do most IMO problems. Not yet though..
Your claims reflect a fundamental misunderstanding of the capabilities of AI. It's like saying, one day humans will be strong enough to fly without aid. ChatGPT is fundamentally incapable of solving IMO problems, just admit it.

Nah it is most definitely gonna be able to solve IMO problems in the future :skull: especially when more of us aops people go into the AI field when we get older.
Just because there are AoPSers working in AI does not mean they will make significant contributions to the development of AI, nor overcome the fundamental issues with ChatGPT.

So true
i mean look at people who said that we would never get to the moon...
everything seems impossible until someone does it
I was never talking about AI in general, only about how ChatGPT and other LLMs have a structure incapable of comprehending rigorous mathematics and solving hard problems like this.

i can't say i agree.
its true that LLMs cant do these things now, but the technological advancements of just AI over the past year is amazing, if u look at it from another perspective.
LLMs take in data and learn from it, like a human brain. They can analyze things from thousands of different perspectives and find one that works. It's hard to say that AI will NEVER be able to catch up to an IMO level participant, as a result.

You are wrong. LLMs have an intrinsic capability to analyse language phrases so it is impossible for them to understand the rigorous first-order logic underlying mathematics, like set theory or geometry.

Have you heard of mathematics formalized tools, such as "LEAN"?
