Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 131 Stack Exchange communities.

A few weeks ago I asked this question on math.stackexchange:

I'm still looking for the name of the problem. This is a computational geometry because I suspect that it has been solved. One the Wikipedia page listing the classical computatational geometry problems, I did not find an exact match for what I'm looking for.

Should I reformulate the question? Embed an image (I could not join an image IIRC because I did not have enough rep) ? Ask the question where programmers could see it (instead of mathematicians) ?

Smells like "send me the algorithmz"...not for SO, no. –  Time Traveling Bobby Jul 12 '12 at 10:05
    
You could start by considering Ross Millikan's comment: are you in fact looking for all lattice squares within a region, or all polygons (of which there are infinitely many)? "the set of non overlapping polygons that we intuitively see" is not a productive definition whether you are talking about mathematics or algorithms. –  AakashM Jul 12 '12 at 10:05
    
I just want to find the name of the problem, or if it is a restriction of another problem. –  Antoine Lecaille Jul 12 '12 at 12:55

For computer science questions, including algorithm questions, I recommend asking on Computer Science Stack Exchange. (I am a moderator there.) I don't know anything about computational geometry, but your question looks reasonable, and there are competent people who visit CS.SE. While my understanding is that all algorithm questions are considered on-topic on Math.SE, they tend to be outliers: you have the wrong target audience.

I believe that Math.SE's policy allows migrating computer science questions when they are unanswered and the asker agrees, so you should flag your question for migration to CS.SE. Please do not repost the question, as having the question in multiple places makes answers harder to find. Since you have only 1 reputation on Math.SE, you won't be able to flag; if you agree to the migration, someone else (e.g. me) can flag it for you.

Algorithm questions are allowed by Stack Overflow's FAQ, but they tend to get a poor reception: if you haven't committed to a programming language, SO is probably the wrong place.

I agree with your proposition to migrate it to CS.SE. I just created an image to illustrate what I'm talking about, but I can't post it because of my low rep. –  Antoine Lecaille Jul 12 '12 at 16:27

If mathematical question's/ algorithm's implementation is needs to be done in any programming language(which are allowed to discuss on SO). And you are facing problems in it.

ie. I have implemented algorithm in language, it should do this but it does this. I tried already this and that, but it still shows that odd behavior. type questions are fine on SO.

Otherwise mathematical questions are not allowed on SO.

Do not forget that "how could I implement this algorithm in language" and "how do I write algorithm in language" are not good questions. –  Time Traveling Bobby Jul 12 '12 at 10:25
    
@UristMcBobby: Yeah. I mean if you are facing problem in implementing logic or any error messages. Then it allowed, isn't it? –  Somnath Muluk Jul 12 '12 at 10:30

Yeah, sure, "I have implemented algorithm in language, it should do this but it does this. I tried already this and that, but it still shows that odd behavior." type questions are fine for the most part. –  Time Traveling Bobby Jul 12 '12 at 10:31
