Source: Use your common sense! (enough is enough)
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]$lim_{n\to 1}^{+\infty}\frac{1}{n}-lnn$[/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 $x^{3}+y^{3}=z^{3}$, do not answer with "$x=y=z=0$ is a solution" only. Either you post any kind of proof or at least something unexpected (like "$x=1337, y=481, z=42$ is the smallest solution). Someone that does not see that $x=y=z=0$ 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.

Serbian selection contest for the IMO 2025 - P6

N an hour ago by math90
Source: Serbian selection contest for the IMO 2025
For an $n \times n$ table filled with natural numbers, we say it is a divisor table if:
- the numbers in the $i$-th row are exactly all the divisors of some natural number $r_i$,
- the numbers in the $j$-th column are exactly all the divisors of some natural number $c_j$,
- $r_i \ne r_j$ for every $i \ne j$.

A prime number $p$ is given. Determine the smallest natural number $n$, divisible by $p$, such that there exists an $n \times n$ divisor table, or prove that such $n$ does not exist.

when you request the grade report in a class, does your grade reflect the grade when you requested the report? or does the final grade reflect the grade by the time the report is generated?

So for example if i request a report at 5-23-2025 and it comes back at 5-31-2025, does the final grade reflect the progress at 5-23-2025 or 5-31-2025?

k Suggestion: Creating Personal Alcumus Problems
franzliszt   35
N Sep 25, 2019 by LauraZed
This suggestion doesn't mean that users can just add problems to the topics like Algebra and C+P for everyone. Instead, it means that users can add personal problems that they came up with for themselves only. For example, if you missed a Algebra question from school, you can add it to your personal Alcumus for reveiw.

It would be cool if you could create new Subjects for yourself too. For example, you could create a "AIME" subject and just enter AIME problems in to practice.

Note: you can even create non-math problems like spelling and vocabulary and physics etc...

Yeah I love that idea! That would be so awesome- like your personal math trainer! But sadly that would be hard to make. It would be way cool if they could! :first:


But for only AoPS related topics, right? U could choose a subcategory and make problems within that??? Oh and would you input the answer and then come back for it when you forgot the answer?

Something like this already exists, it's called Quizlet.
This is an interesting idea though.

Good idea!
I could use this to add Pokémon themed word problems!

If I were in charge of AoPS, I wouldn't include this, because it takes a ton of effort to produce one quality problem. Sure, the AoPS staff borrows problems, but it also make many of its own. With that amazing amount of work and effort put into the already available topics, having you own problems would make the effort less appreciated. A great part of Alcumus is that they are selectively chosen as good, high-quality problems. As post 20 (Madelyn) noted, use Quizlet for this this.

Without any offense made to anybody, allowing you to put your own personal problems in will detract from Alcumus, because it is hard to find good quality problems. The AoPS staff are paid to do this, and have done so excellently, and I've only Reported a few of the problems for things, many mostly minor things.

There are other problems as well, such as solutions. Would solutions be included? Would you learn from those questions without solutions? What if the question from you school had no solution? Would you write your own? Would you learn form your own solution?

In short, I do not agree with this idea.

@OliverA - I think everyone is saying that you could make a whole new topic for your personal problems. It would be cool, but there are a few issues with this:

1) To make it possible for Alcumus to grade your response, you have to put the answer into the system, partially destroying the point of it

2) Alcumus has a whole database of correct possible responses, and it would be complicated for users to figure out all of these

3) There are other websites like Quizlets that could serve the same purpose and it would save AoPS developers a lot of work.

Edit: so overall it sound super cool, but when we look more closely, it may be less exciting than we first expected

Correct me if I am wrong, but websites like Quizlet don't have AI. Quizlet just spams flashcards for you. If you get one wrong, it just gives you the card again. This is different from Alcumus, which has an intelligent AI system. Websites like Quizlet have a low AI compared to Alcumus.

This is literary the only reason I support this suggestion: Alcumus's awesome AI. Unless the Site Admins make the AI code open-source, which I highly doubt, I would love to see this near-impossible suggestion come true.

Well, for these problems to work in Alcumus, others would have to do them so that the rating gain/loss is set for other users. Correct me if I'm wrong, but rating is really what makes Alcumus work, telling it which problems to give you and such. If there are no others to figure out what the rating gain/loss would be for each problem, then there couldn't be rating for those problems, and then how much different would it be from Quizlet?

Continuing the idea also adds the solution stuff, see my above post, and also there could be lack of problems. If you have like three problems in you Customized Alcumus, then, well...

Edit: I've decided to leave this to the AoPS Staff, because, well, I can only say my POV. Also please note that I'm writing these posts on the fly, so my brain might not be working correctly.

Quizlet does not have a rating system. It is "binary:" right or wrong. The rating system is much more superior than wrong or right. Rating systems could still apply to problems as long users don't gain points from them. The goal of Alcumus is to learn by doing problems, not by gaining points, so I don't think users will care about the points. (I don't care about points.) Also, no one can remember all the answers to the problems they submit. If I submit problems, I'll come back to them weeks later and actually learn from them. If users are just answering questions like "1+1," then it's their fault. They aren't taking advantage of this opportunity to learn given to them by AoPS.

If there's a lack of problems, it's not the customized Alcumus' fault. It's the user. I would probably input 50 to 60 problems into it. And that's just for one subject...

The only problems about this suggestion is time and money. It would take a lot of time, and Alcumus is free. Many websites, like Quizlet, charge money for their "pro" services. Alcumus would probably be still free if this suggestion is considered (again, I doubt this suggestion will even be accepted), which makes it even more superior than Quizlet. Quizlet does have fancy features, such as pictures and pronunciations, but I almost never use them for the stuff I study for (physics, chemistry, history, etc.).

Edit: Good idea. Mine is not working properly too I think... :P

Point conceded, Alcumus does have a better AI and a better tracking system for questions you have a hard time answering. This would definitely be cool addition to Alcumus, but in the midterm or if this never happens, we aren't left without options. Don't get me wrong, I hope this is implemented, but I do want to be able to point out the nuances of this idea. I just saw riben's 6th edit and I'm responding to it: I use quizlet without paying anything, and it work fine, I couldn't ask for more, you do get a lot of adds in the margins though...

Edit: and yes, the aops staff are going to make a better decision than we can

I paid for Quizlet pro, and I regretted it. I never needed those fancy features. All I need was a fancy AI, and Alcumus has it. Again, another advantage that Alcumus has. I have seen no website that offers an AI with the same level as Alcumus' or even greater.

If the Site Admins do deny this, we, the AoPS community, can try to create our own by mimicking the Alcumus AI (as long we don't publish it outside of AoPS I think). Alcumus follows a pattern. If we could identify it and use it to our advantage, our dreams will come true. Of course, observing a highly intelligent learning system will be difficult and time consuming. Not including the time it will take to make it...

Also, custom problems might mean custom quests! Now, that will make all our custom quests idea in the Alcumus forum be a reality! Wait. I'm getting ahead of myself. Maybe later...

It should be noted that the Alcumus AI is heavily influenced by how others answered the same problem. It basically would not work at all for questions that are only given to one person.

Never knew that, so I guess a revision of this suggestion is necessary...

How about creating custom problems group (a group of problems)? These group of problems will be public, and other users can access them. If they want to do these problems, they can add the problem group to their own Alcumus. For example, let's say you and your friends are learning the multinomial theorem. You create a group of 50 to 60 multinomial problems. Your friends add your problem group to their Alcumus, and now Alcumus' AI can work properly since there are other people doing the problems. Will this work?

Edit: I just realized this could solve another problem. People say this will be useless since the person who creates the problems has to input their own solutions and answers. If they share these problems to other people, a deal can work out. For example, you want to learn multinomials, but your friend wants to learn geometric probability. You can write geometric probability problems for your friend, while your friend writes multinomials problems for you. Then, you and your friend share each other's group of problems. That way people can actually learn and there are multiple people! Therefore, Alcumus' AI should work. Of course, there needs to be more than 2 people. But finding people to do problems shouldn't be a problem unless these problems are pointless ones, like "What is 1+1?"

If we were allowed to make topics/groups of problems public accross all AoPS users, it could turn messy because inevitably, they'd want to edit them to be more clear, more answere options etc. etc. Perhaps make a similar system to Quizlet where the original creator can choose certain people who can edit the "set" and reports would go to them? Private sets may also have a place if this were implimented

Yes. There could be admins/mods of group, where admins can add/remove problems and mods could only edit problems.

I'm not sure about private. If people aren't interested in a problem group, they can just ignore it. Private groups might be unnecessary.

I also agree on reporting groups. People might add inappropriate questions, so groups should have the option to be reported. If not, people could just email the Sheriff.

Thanks for sharing the idea! However, we're not currently planning to add a functionality like this to Alcumus.

(If you want a slightly better than standard flashcard-like system where you can make your own decks, I liked Memrise in college – it would adapt how often it gave you particular cards based on whether you got them right or wrong previously. Since college is quite a few years ago for me, can't vouch for how Memrise works nowadays, but y'all could check it out.)
