@VTCAKAVSMoACE But there's only eleven numbers there, how could it get to seven already?

My grandma had Alzeimer's and I guess as part of the diagnosis the doctor had her count backwards from 100 by 7s. My mom went to the appointment with her and couldn't do it herself. :P

12:00 AM

@AlexA. that's just mean

VTCAKAVSMoACE

@AlexA. ouch

It's like sobriety tests where they tell you to do the alphabet backwards. I know plenty of sober people that couldn't do that.

I can never do that

@Doorknob That doesn't mean you're drunk now.

@Geobits "Well officer, I can't recite the alphabet backwards but I can write a totally sober computer program that does it."

@Maltysen oh... yeah :P

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

You mean drive drunk?

12:04 AM

@Geobits underage drinking, or just in general?

I'm pretty sure no one should do that ever

@AlexA. No, underage drinking.

Oh, yeah

17 ftw

Hm, 16?

No, I think 17

Not that I'm advocating it or anything

hey everyone @Geobits totally just advocated underage drinking

@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.

@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 >_>

public transcript shit

@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.

in Beep Boop Maggot, 22 secs ago, by Bald Bantha

[BOT] I think alex a. somewhere I would want to go

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

@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

12:11 AM

@AlexA. I wish more people would do that. Parents really should be the ones teaching this shit.

Side note: People will star anything with 'fuck' in it, won't they?

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

@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".

Right

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

Are you still smoke-free??

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.

12:19 AM

Just ~~let alcohol fill the void~~ clear your mind? ¯\_(ツ)_/¯

lol, well staying busy helps more than anything. "Clearing the mind" is the opposite approach.

@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.

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

@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.

@AlexA. there was some speculation about that.. but his cover couldn't possibly last that long

@AlexA. And possible take blows to his ego??? nooo...

@aditsu I can't find it now, but that reminds me of a meme I saw where it was pointed out that Hitler fought in the army (in WWI) and was a competent politician, neither of which Trump did or is, and concluded that comparing Trump to Hitler is an insult to Hitler.

... O_O

^

That was a ride from the beginning to the end

12:51 AM

@El'endiaStarman well, Trump is actually a very competent politician (not in the sense that he has good policies, but in the sense that he knows how to gain supporters and manage issues that come up); as for fighting in the army, I don't necessarily see that as a quality

just found this:

@BaldBantha Best thing ever. The JS plugin to end all JS plugins.

@aditsu Well, Trump dodged the Vietnam draft.

12:53 AM

@AlexA. It is curious. Part of me wants to believe that a lot of it is simply intended to rile up the public and the media. He may really believe what he says but he can't possibly be dense enough to intentionally alienate all his political allies.

@El'endiaStarman good for him

@mınxomaτ How did you get that one?

@aditsu Trump definitely knows how to rally supporters, that's for sure. He is, however, first and foremost a businessman. Hitler, on the other hand, had a seat in Germany's Parliament or whatever it was called before he made a successful power grab.

@BaldBantha I'm magic.

@HelkaHomba I've come to think that he may actually be that dense. If there's one thing that's apparent about his character, it's that he's arrogant enough to think he can do anything on his own, with or without others' support.

1:20 AM

Is there a name for an algorithm that solves this problem?

@EᴀsᴛᴇʀʟʏIʀᴋ noice

not mine

from reddit

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.

@mınxomaτ p=q=n, problem solved

1:32 AM

You know that's not what I meant.

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

Are p and q integers?

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

that's a different problem ^

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

Maybe that's clearer.

1:35 AM

that problem would be p * q == n

@aditsu Not really, if all are integers.

yes really, read it

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

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

for that question or for your question? :p

Damn it, you know what I mean.

1:38 AM

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

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

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

@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

After which I rephrased.

the rephrased version is extremely vague

@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"

1:43 AM

@Sp3000 Got a link?

@mınxomaτ no, the SO question is clear, and "p * q == n" was not meant to be a solution; are you actually trying to get an answer or do you just enjoy arguing? :p

your first post asked for an algorithm name

1:46 AM

@DrGreenEggsandHamDJ That's pretty helpful

that's yet another different problem :)

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

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

@DrGreenEggsandHamDJ Exactly.

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

Anyway, that solved it.

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

1:50 AM

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

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

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

@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.

@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

@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

2:00 AM

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

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

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

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

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

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

2:04 AM

Oh, I get what you mean.

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

4 and 6 are better

No, 6 and 4.

Ninja'd

and 5 and 5 are best

^

> In case of a tie, the optimal solution is the one with less empty chairs.

It works with that rule to

2:07 AM

5 5 or 4 6?

5 5 has a score of 1, 4 6 has a score of 2.

I mean in the original question, not the chairs question

Oh, the original question isn't super clear.

if you mean the SO question, the answer is 4 6

as 5 * 5 != 24

Oh alright

2:09 AM

Haha, I love this site. This is the only place where I can over analyze the difference between factors in a number and people would actually care.

I'm pretty sure next to none of my irl friends would care.

lol

@DrGreenEggsandHamDJ well, now I'm really curious.. how low can it go? :)

How low can what go?

the small factor

1?

2:20 AM

no, I mean the small factor in the solution, relative to sqrt(n)

in @DrGreenEggsandHamDJ's challenge

Oh, haha. I found a couple outliers. 91: (7, 13), 50: (5, 10)

those are still within 2

I'll see if I have the script I used to generate the test IO, and run it much higher.

code-golf math

Yes, but we are finding whether there are any small p

relative to n?

relative to sqrt(n) mainly

so I should be tracking sqrt(n)-p

2:32 AM

Uh... I think we're trying to find the biggest q-p

Although, that grows as n does, so maybe that's a better idea.

@LeakyNun either that or p, both of them relative to sqrt(n)

it looks like sqrt(n)-p is not limited by a constant

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

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

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

Portal Portal

2:35 AM

Portal

@DrGreenEggsandHamDJ What are you tracking?

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.

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?

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

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

2:41 AM

code-golf does mean that the shortest answer wins.

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

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

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

@MichaelCodes That hasn't been true in practice.

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

2:43 AM

Haha, you even have a 'C' answer.

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

@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

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

Depends who you ask.

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

ok, thanks both maitysen and leakynun for the confirmation

2:45 AM

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

@aditsu What should I be looking for?

whatever you want :)

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

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

ok, thanks.

2:47 AM

@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

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

initial conjecture: p > 0.63*sqrt(n)

@aditsu Now that's something I can search for
