FWIW, I agree. Everyone should do it at least once. Not that I'm advocating it or anything. Shit.

You mean drive drunk?

Maltysen

@Geobits underage drinking, or just in general?

I'm pretty sure no one should do that ever

@Geobits I'd probably argue against for the case of really addictive illegal drugs. If you try it once and like it, you shouldn't seek it out again...

e.g. meth

@Maltysen Hookah is always legal though; it's just tobacco.

Maltysen

@Geobits idk, kinda makes you dizzy after a while, but overall wasn't bad

@AlexA. the flavoring may or may not have had tobacco in it >_>

Geobits

@AlexA. Right. I can understand that viewpoint. I don't necessarily agree with it, but I understand it. Most of the people there were just being hypocrits and jumping on the side they thought the instructor wanted to hear. It was actually good fun debating the entire class on my own.

Geobits

This was in the military, so there was a big "drugs are bad, mmkay" mentality by leadership. Not necessarily amongst the general populace.

Alex A.

@Geobits My friend's girlfriend's mom said to her before she started high school, "You're going to be exposed to this anyway, so if you can finish either of these, you have my permission." She then handed her an entire Manhatten and a cigarette. So she doesn't drink or smoke and she's in her 30s now. :P

I guess a bad experience when you're 14 will keep you off of it for life

@Geobits In general I agree with you with the exception of the ones that can seriously wreck your shit (again, e.g. meth).

Geobits

@AlexA. Yeah, I don't have any experience with seriously hard drugs. However, I do believe in personal freedoms, and it's hard to argue against it within that framework. Not impossible, but considerably more difficult than "it's bad for you, so you can't do it".

Alex A.

Right

Geobits

Then again, I smoked for 15+ years knowing full well it wasn't good for me, so what do I know? :P

Alex A.

Are you still smoke-free??

Geobits

Yes. And it's still driving me a bit crazy >_>

Especially times like these, when I'm doing nothing between drinking sessions o_o

Seriously, someone fax me a cigarette.

Helka Homba

@Geobits It can also be bad for anyone you're associated with - friends, family, dependents especially. I don't have strong opinions one way or the other here, just that is another aspect.

aditsu

@HelkaHomba so.. q~4%3%!

Geobits

@HelkaHomba True. I didn't really want to get into that aspect of it, though, since it can be used for severe restrictions on liberty. It's hard not to slippery slope that one imo.

mınxomaτ

I'm basically look for the most efficient solution for this: Given n, find p and q, where p * q >= n AND |p-q| is as small as possible.

aditsu

@mınxomaτ p=q=n, problem solved

mınxomaτ

01:32

You know that's not what I meant.

aditsu

if not, then p=q=ceil(sqrt(n))

Alex A.

Are p and q integers?

mınxomaτ

@AlexA. Yes, see this: stackoverflow.com/q/16266931/3750388

aditsu

that's a different problem ^

mınxomaτ

Essentially convert 1 dimension into 2 dimensions, so that the latter is as square as possible.

Maybe that's clearer.

aditsu

01:35

that problem would be p * q == n

mınxomaτ

@aditsu Not really, if all are integers.

aditsu

yes really, read it

so for a prime number, the unique solution would be 1 and n

mınxomaτ

OK, let's try this again: Is there are more efficient solutions than those given in the SO answers.

aditsu

for that question or for your question? :p

mınxomaτ

Damn it, you know what I mean.

aditsu

01:38

I know you know I know what you mean, but I don't actually know what you mean

Sp3000

Since we all like strawpolls so much: strawpoll.me/10400582

aditsu

I have at least 3 different possibilities for what you might mean

mınxomaτ

@aditsu With the addition of being as square as possible. Simply p * q == n does not give any indication that the difference between p and q should be as small as possible, which is what both I and the question clearly state.

Seth Kitchen

I have an issue understanding javascript callbacks. Can anyone help?

@mınxomaτ yes, the SO question includes being as square as possible (I thought that was clear); I was only emphasizing the part where that question is completely different from what you said

the rephrased version is extremely vague

mınxomaτ

@aditsu It's exactly the same as the SO question, but condensed. In any case "p * q == n" is neither a solution for my rephrased question nor the SO question.

Looking at OEIS - if it helps I think these are called "central divisors"

your first post asked for an algorithm name

01:46

@DrGreenEggsandHamDJ That's pretty helpful

aditsu

that's yet another different problem :)

Dr Green Eggs and Ham DJ

Although it's still not clear why you don't just do p=q=n is there a second criteria beyond p*q>=n?

Smallest p*q? That's essentially my challenge, minimized |p-q| and p*q-n

aditsu

@DrGreenEggsandHamDJ apparently that's not exactly what he wanted, but he won't clarify

mınxomaτ

@DrGreenEggsandHamDJ Exactly.

@aditsu If you think that, you misunderstood the SO question.

Anyway, that solved it.

aditsu

@mınxomaτ nope, absolutely NOT; the only thing I'm not clear about is what you want to solve

Dr Green Eggs and Ham DJ

01:50

@mınxomaτ what's more important to minimize, the difference in absolute value, or "missing chairs" if you will?

aditsu

SO question: clear, PPCG challenge: clear and DIFFERENT, mınxomaτ's question: ¯\(o_º)/¯ no idea what you want

Sp3000

Hmm I'm not quite sue there's an efficient algorithm for that question tbh

Dr Green Eggs and Ham DJ

@Sp3000 do you mean my challenge, but for efficiency, not code length?

Hmm, now I wonder what the efficient way is. I did it in O(n), but you can probably do a lot better.

aditsu

@DrGreenEggsandHamDJ I'm pretty sure you only need to try 1 or 2 values going down from sqrt(n)

oh wait, there could be more

but still, limited by the differences you find

O(sqrt(n)) in the worst case

Sp3000

@DrGreenEggsandHamDJ I mean the general problem of finding the factor closest to sqrt(n)

Since factorisation in general is unknown whether it's easy/hard

Dr Green Eggs and Ham DJ

02:00

@aditsu How can you objectively and efficiently determine when you've hit the best solution, descending from sqrt(n)

aditsu

@DrGreenEggsandHamDJ when the factor difference becomes greater than the best score you found so far

Dr Green Eggs and Ham DJ

Is it strictly increasing though? I don't think it is.

aditsu

yes it is, if one factor goes down, the other one can't go down too

Dr Green Eggs and Ham DJ

No, because factor difference isn't the only thing. There's also p*q-n to consider.

aditsu

yes, but the difference alone can become greater than the score, then you stop

Dr Green Eggs and Ham DJ

02:04

Oh, I get what you mean.

Leaky Nun

like for n=24 p and q should be 3 and 8?

Dr Green Eggs and Ham DJ

Oh, the original question isn't super clear.

@aditsu What does relative to sqrt(n) mean?

aditsu

I mean express it as O(something related to sqrt(n))

Dr Green Eggs and Ham DJ

Another interesting one: 8283 --> (76, 109)

Leaky Nun

@DrGreenEggsandHamDJ What are you tracking?

Dr Green Eggs and Ham DJ

if f is the optimal chair arrangement for a given N, I was looking for max(diff(f(n)) for n in range(x))

where diff is just q-p

and x was 10000

whoops, max, not min.

MichaelCodes

question: I posted my first golf question, and I got 9 replies. Is there a convention about selecting an answer? i.e. do I have to choose the shortest, which typically would mean V or pyth, or what other criteria?

Maltysen

@MichaelCodes shortest, and if there is a tie, then by time of posting

Dr Green Eggs and Ham DJ

Typically, yeah, the shortest that get's each test case.

El'endia Starman

code-golf does mean that the shortest answer wins.

Leaky Nun

@MichaelCodes You don't really have to accept an answer.

Dr Green Eggs and Ham DJ

@LeakyNun Shh, this might be the only code-golf I ever win!

MichaelCodes

if the shortest wins, then people wouldn't bother with perl, sql, etc... which could be interesting but more bytes.

El'endia Starman

@MichaelCodes That hasn't been true in practice.

Leaky Nun

@MichaelCodes this is an ongoing problem in debate, so I don't think you should bother

Dr Green Eggs and Ham DJ

02:43

Haha, you even have a 'C' answer.

MichaelCodes

seems to me that it's fun for people regardless of whether they "win".

Maltysen

@MichaelCodes the usual answer to that is that "winning" in terms of the green checkmark doesn't really matter

a) it usually never happens for a long time

and b) its only 15 rep

MichaelCodes

ok, so it's not bad decorum to leave it open and unanswered?

Dr Green Eggs and Ham DJ

Depends who you ask.

I've accepted one in all of my challenges so far.

MichaelCodes

ok, thanks both maitysen and leakynun for the confirmation

aditsu

@DrGreenEggsandHamDJ I think we're looking at somewhat different things

Leaky Nun

@aditsu What should I be looking for?

aditsu

whatever you want :)

MichaelCodes

And thanks DrGreenEggs for your crazy short 13-byte totally cryptic answer

Dr Green Eggs and Ham DJ

@MichaelCodes I'd say this is the most relevant answer: meta.codegolf.stackexchange.com/questions/8706/…

MichaelCodes

ok, thanks.

Dr Green Eggs and Ham DJ

02:47

@MichaelCodes Haha, anytime. I've been working on V for a while, and it's cool when I get a challenge it can actually do well in.

trichoplax

I'm in favour of phasing out the green tick mark since we aren't quite a Q&A site, but until that happens I tend to accept for all my challenges. For non-golfs it makes more sense but I accept for golfs too

aditsu

sqrt(n)-p seems to be sublinear in sqrt(n)

initial conjecture: p > 0.63*sqrt(n)

Leaky Nun

@aditsu Now that's something I can search for

aditsu

it's quite weak but it's a start
