@Rusher Meta is an art all its own for sure. I have a couple questions on meta.se that were voted down quite quickly.

undergroundmonorail

1:46 AM

Woo, saved 6 bytes on my pigeonhole sort. len('i is not None') > len('i!=None')

Additionally, I keep spelling it pidgeonhole on my first try. Pokemon has ruined me.

Geobits

pidgeothole?

New pokemon games this November... my kid's already in waiting mode.

Ok, so am I ^^; ...

undergroundmonorail

My friends are all super hyped. I'm interested, but I don't really love Hoenn the way they do.

I'm still getting it day one, don't get me wrong. :P

Geobits

I was never a big Hoenn fan, but I heard it was going to be quite different from the originals. Haven't seen much on it, so I couldn't say for sure.

That reminds me, I should probably work on updating Pokedextra. I haven't even gotten X/Y data in yet ><

undergroundmonorail

1:51 AM

Oh, that's cool.

I looked up Pokedextra. :P

Geobits

Yea, I had fun working on that. It was originally just a project for my kid, so he'd quit asking to look stuff up on the computer every 5 mins or so.

undergroundmonorail

Haha

Do you play on Showdown at all?

Geobits

Nope. I've got some nicely-trained pokes, but I haven't gone competitive. I just use them to lay the smackdown on friends and family.

undergroundmonorail

Heh, fair.

grrr i'm so mad, i tried to buy something with my hard-earned tokens on tetrisfriends but it didn't work at first so i clicked the button a few times, eventually it went through but it charged me for all the attempts at purchasing it that i could afford, so instead of losing 1000 i lost 4000 and couldn't afford the other thing i wanted to buy

Geobits

The internets have trained me not to ever click the submit button more than once when paying for something. The hard way.

undergroundmonorail

1:58 AM

Luckily it wasn't actual money, just tokens that you get for playing

But still, getting tokens takes a long time.

Geobits

Shit. Playing is time, time is money, et cetera and so on.

undergroundmonorail

I contacted support and maybe they'll give me my tokens back? It only happened an hour or so ago so I'm not surprised at the lack of a response so far

@Geobits It's not like I'd be working if it wasn't for tetris, I don't think "time is money" applies :P

Geobits

Don't know the site, but anything with decent customer support should be able to see it as a dupe.

Shhh! Customer support doesn't know that :p

Quincunx

@Geobits Blech. The new pkmn games are terrible IMO. Gen III or below is good. The new ones add a perspective tilt that looks bad. Also, the ideas for new pkmn are weird (e.g. saggy pants teen).

Gen III has a nice top-down view

And the pkmn haven't gotten strange yet.

undergroundmonorail

The new pokemon are so good though! And the perspective tricks are gone as of X/Y, since it's just actual 3D now.

Quincunx

2:03 AM

Ugh. Actual 3D? And the battle graphics are too good. I don't like graphics that are too good.

Geobits

@Quincunx Ah, damn. I stepped on your lawn again, didn't I? :p

2

undergroundmonorail

Honestly, my biggest complaint with gen III and below is the stupid, stupid way they handled physical/special attacks. In gen IV they were like "Hey, what if we stop being idiots and make each move either physical or special, instead of saying 'every water type move is special, every fighting type move is physical, blah blah blah'".

Quincunx

@Geobits??? Stepped on my lawn? Haven't heard that before.

Geobits

I've heard the "new pokemon are weird" argument before. I can pick a few out of any generation that suck.

Quincunx

@Geobits Me too. Gen III: ... I can't think of it right now...

Geobits

2:07 AM

urbandictionary.com/define.php?term=get%20off%20my%20lawn

Quincunx

@undergroundmonorail That's true. But it makes some things interesting

Geobits

Gen 3? The immediate picks for me are Plusle and Minun. Gimmicky as hell, and no good at anything, really.

Quincunx

@Geobits Are you implying that I'm old?

@Geobits Actually, they are very good. Try the battle frontier in 2 on 2. They can save your pkmn.

Geobits

Nah, it's a generic "back in my day, we had real pokemon" thing :p

I'll take a couple extra sweepers any day.

undergroundmonorail

@Quincunx I don't play much doubles, but as far as I'm aware they don't get used at all in pvp

Quincunx

2:08 AM

@Geobits I still have pkmn cards. Even have one that is in Japanese and says Pocket Monsters.

Geobits

I never got into the card game. My son's starting to, though :)

Quincunx

@undergroundmonorail They aren't terribly useful, but in battle factory (where you get to use rental pokemon), they can be invaluable.

Geobits

Ok, I could see an argument for them in rental. But you can make something work with just about anything in rental.

undergroundmonorail

@Quincunx I suppose that's true. I'm more of a Singles guy myself, didn't experiment in 2v2 much.

Quincunx

@Geobits I didn't play it too much, but I did have fun constructing decks. I constructed a normal type deck once. It was a lot of fun playing it. But that was years ago. The cards are now in a box that is collecting dust.

Geobits

2:11 AM

Sounds like my MTG cards.

Quincunx

@Geobits Some pkmn are useless in rental. :-). They really are useless. Well fine, you can take out half another pkmn with them, but that means they are terrible.

undergroundmonorail

You know what pokemon is underrated? Ditto.

"Oh, you're setting up? Let me just switch into Ditto real quick, steal your stat boosts, outspeed with Choice Scarf and wreck your whole team."

Geobits

I like Ditto and all, but it's a pain to get a good one. It's not like you can breed one with good stats.

undergroundmonorail

All that really matters is HP, everything else is copied from the target.

31 HP IV and Imposter is enough.

Geobits

True...

Now I may have to go play around with a ditto.

undergroundmonorail

2:14 AM

I mean TECHNICALLY you want 0 speed and 31 SpD so that you win a Struggle war against another Ditto, and you can tank a hit from a Zoroark if you mispredict, but in practice it doesn't matter.

Geobits

Gen 6 it's scandalously easy to get a 31 IV anyway. Friend Safari and all that.

undergroundmonorail

Oh, and you might want a good Hidden Power. I had a friend RNG me one from gen V with HP Ice :)

Ah, yes, I found what I was looking for. Ditto is fantastic and if you disagree you're wrong.

Oh, and Ditto can copy Mega pokemon, too. I forgot about that.

Quincunx

@TheDoctor but }}big isn't working

undergroundmonorail

@Quincunx Earlier he said he made it him-only because there was an exploit.

Quincunx

@undergroundmonorail Probably when I just typed }}big

Geobits

2:20 AM

Oh, I didn't know Ditto could go mega. Makes sense, but didn't know.

undergroundmonorail

It's especially cool since it doesn't use up your one mega-evo for the battle.

Geobits

Hmm. Well I've got a few Ditto with good HP for breeding purposes. Maybe I'll give one a spin.

Q: Duct Tape some sorting

Your job is to make a sorting algorithm. The catch, you must copy it from Stack Overflow. Your program will take an input array (or equivalency), and output a sorted permutation of the array. Your program must consist solely of copy and pasted code blocks from Stack Overflow. You may not take...

New post! Pathological Sorting

undergroundmonorail

I made a new email account specifically for applying for a job (undergroundmonorail@gmail.com doesn't sound very professional). I tried to get incoming emails to redirect to my normal address, but it wouldn't work for some reason so I gave up. Now, whenever I check to see if my potential employer has contacted me, I see the test email I sent to see if it's working

Is adding a tag a significant enough edit to be worth doing? That new sorting question is begging for underhanded.

Eh, I'm just gonna do it, if it gets rejected then who cares.

Geobits

12:58 PM

If the tag is correct, I don't see a problem. If you're doing it en masse to reap the rep, that may be different.

Underhanded it too close to trolling in my opinion

I have two lists, a and b. I want to reassign the content of a into b and the content of b into a. or in other words, after running a few operations with two lists, I want to switch the names of the lists. so that the list that was named a would now be named b, and the list that was named b woul...

python

Rusher

@durron597 Up until just last week I was swapping items like temp=a;a=b;b=a; in python

undergroundmonorail

2:01 PM

Even if you didn't know about the tuple packing/unpacking way to do it...

>>> print a, b
10 5
>>> a ^= b
>>> b ^= a
>>> a ^= b
>>> print a, b
5 10

B)

(probably a bad idea in practice because unreadable and the interpreter doesn't know what you're trying to do so it can't optimize at all, but B\) regardless)

Rusher

I can't Google the ^= operator

I'm too lazy to think of a word that would go beside it and put it in quotes

like "^= operator" Python

undergroundmonorail

a^b does a bitwise xor of a and b, a ^= b assigns the result of a^b to a.

@undergroundmonorail Oh man the day I finally got pointers in C

it was like a whole universe opened up to me

"why would you need to know the address of something in memory? wtf?"

undergroundmonorail

@durron597 I'm still struggling along in the high-level languages. Maybe I'll get there one day :P

Out of curiosity, why would you need to know the address of something in memory? I'm sure it's useful I just can't think of anywhere I'd want to use it.

Rusher

If you are hacking a game, you often need the location of items in memory to 1) know things you shouldn't know and 2) modify things you shouldn't modify

durron597

think about if you want to iterate through an array

undergroundmonorail

That's a good point

durron597

2:24 PM

pointers are about two things

relative locations in memory

e.g. in an array x[0] and x[1] are adjacent in memory

Geobits

c pointers clicked for me one day when working with strings. err... char arrays.

durron597

and about passing by reference

Geobits

my only programming before c was in basic/qbasic, so it was definitely foreign.

durron597

if i have void swap(int x, int y)... it can't be done!

but if you do void swap(int *x, int *y)

undergroundmonorail

Ahhh

durron597

2:26 PM

then you are passing the memory locations of the two variables

Rusher

I remember completely getting star (*) pointers in C++, and then the professor introduced the ampersand (&) for references and I was lost again. Took me forever to stumble back from that

2:29 PM

oh, once i understood * i understood &

* = a -> b, & = b -> a

it's like + vs -

undergroundmonorail

@durron597 In python, that syntax does something entirely different. If a == (x, y, z), then f(*a) == f(x, y, z)

Or something. That specific piece of syntax constantly trips me up.

durron597

man when i was first learning python

i hated it

"this is the bastard stepchild of java and laziness"

i'm such a purist ;)

Rusher

Purists have a hard time with Python

because Python has a Pythonic style, and purists have to learn it all

Meanwhile, the rest of us can just use regular constructs until we learn the Pythonic ones

Geobits

my only problem with python is the evangelists who proclaim it to be the "One True Language" :p

undergroundmonorail

Python is the only language I've ever truly loved. Not that I've learned too many other languages.

First I learned Turing for school, a dumb made up language for stupids.

Rusher

2:32 PM

It would be my one true language if not for the poor class declarations. Who declares methods with __ImAMethod

undergroundmonorail

Then C#, again for school, but I found python on the internet and adored it from the start. I don't even know why.

Geobits

Oh, @Rusher . Disregard my TwoSwap results yesterday. There was a bug in the controller. It's been fixed now, but I haven't tried to run the test again. (I still assume it's not perfect, but no proof)

Rusher

@Geobits I found out that what we are studying is called Pairwise Exchange

Except that instead of reconnecting the broken path in the best way possible, we are swapping them

So they just get reconnected in the exact opposite order

Usually you would take out two points and place them back where they fit best

but for your problem, that might shift the entire list and disqualify us

I think you managed to eliminate the "greedy" solution and made it a hard problem again

Geobits

3:04 PM

Hmm. A Game with a TwoSwap and two ThreeSwap has been going for a while now. A couple hundred turns in, the distance in down to 3k from 12k.

Rusher

One swap means two points displaced right?

Geobits

Even if it's not optimal, the TwoSwap is looking pretty good. ThreeSwap sometimes times out, so it's riskier.

Rusher

2 swap means at least 2, and at most 4?

Geobits

Yes.

undergroundmonorail

@Geobits Keep track of the time so far, if it's > 58 seconds spit out the best one you've found so far.

Rusher

3:06 PM

Well, they get 60 seconds per turn

Geobits

@undergroundmonorail The way this one works is that it spits out the first it finds, so that wouldn't help much ;)

It's just that there are 5050 possible swaps for each depth, so 5050^3 things to look at.

undergroundmonorail

Oh. I misunderstood how the bot worked :P

Geobits

It's down to path length 2800 now. If my math is right, a rough lower bound for optimal is around 1400 for this size problem.

If that's not right, blame either Wikipedia or my bad understanding of their math.

Rusher

3:27 PM

@Geobits can you copy and paste your test input here?

I don't want to generate a 100 element list lol

Geobits

I might be able to later. I have to flip a switch to make it output that. With it on the console is a pain to read, so I usually turn it off. Can do later.

Alternatively, you could just download the controller which will generate them for you :p

Rusher

oooookkkkkkkkk

Quincunx

Does anyone know what this guy means with his 4th point?: codegolf.stackexchange.com/a/27036/9498

Geobits

Oh, but that lower bound was for Euclidean. If you estimate an average conversion of sqrt(2) from Euclidean to Manhattan, it comes out around 2k.

Quincunx

4. Store the second largest element of the second helper (this is allowed, right?)

Geobits

3:34 PM

From a quick glance at the code, I don't know what he means.

Looks like he's literally just storing the second-largest element size from one of the spare stacks in a variable.

Quincunx

To me, it looks like he is storing it, but not popping it. So he created a reference to it.

@Geobits In your Potato Salesman (I will forever call it this. The salesman sells hot potatoes and needs them to not get cold), is multi-threading allowed? You never mention it, and your computer's specs say that you have 4 processors.

Geobits

4 processors with 2 threads apiece, to be exact. I'm surprised nobody's asked yet. Yes, it's allowed.

durron597

Geobits

Since each player is playing sequentially, I don't have to worry about having a bajillion threads going.

Rusher

@Geobits If someone beats me, let me know and I'll add more lines of code for 3 points lol

I'm basically hard coding the depth to keep it fast

Quincunx

4:33 PM

@Geobits I thought that each processor can really only do 1 thread; more threads are imitated threads.

Geobits

@Quincunx In theory, yes. In practice, I've see dramatic speed increase going from 4->6 threads (like for my flood-paint program)

Imitated or not, they seem to work the same.

Quincunx

Perhaps the processors can execute the extra threads when doing some long operation, or perhaps if the programmer doesn't use the extra threads, some other process on the computer will.

Geobits

Probably some voodoo like that. I only go so deep into the hardware side of things. Press buttons, make work.

Quincunx

@Geobits But I needed to understand how it works. That is how I think for many different things. So now I know how processors work.

Geobits

Oh, I totally get that. I'm that way with most things. The intricacies of modern CPU design still escape me, so I've accepted that level of abstraction. :)

Quincunx

4:43 PM

Yes, I don't totally get it either. But that doesn't stop me from trying.

Wow. I was thinking of multiprocessing. This is multithreading.

Rusher

5:18 PM

@Geobits Is it legal to continue outputting garbage after I output the result?

Nvm

"the output consists of only and all the 100 points present in the input"

Geobits

If it's comma-separated, the program would probably let you. It would reject bare garbage, since that would be attached to the last comma-separated value (like your \n issue earlier).

I haven't tested that, but it splits on commas and takes the first two hundred tokens as input.

Rusher

@Geobits I wrote a multithreaded bot

can someone please check if I'm talking nonsense here? codegolf.stackexchange.com/questions/27028/…

Rusher

6:21 PM

@m.buettner Seems irrelevant to me. The output has to be accurate according to that massive formula, but you don't have to actually use that formula to get the output.

m.buettner

I'm not sure how that changes anything?

Rusher

I'm saying that the burden lies on you to prove that you actually need 10^37 digits for an output that is only 9 digits long

m.buettner

if I compute said formula for x = 90, n = 50, the accurate result is 10^37.

I'm not talking about intermediate values

Rusher

I was under the impression that his formula was only an accuracy checker. Is it wrong?

Geobits

Since it's talking in radians, x should probably be modulus 2PI before plugging it into the forumla. Not that the question mentions that.

m.buettner

6:25 PM

it's an approximate computation... it's only accurate if you include all terms up to infinity. since we're truncating it's largely inaccurate far away from 0.

@Geobits ah, that's a good point

Geobits

The 90 limit is very.... misleading.

Rusher

I thought sin(x) had to be between -1 and 1. I don't understand how an approximation ends up at 10^37. You guys have completely lost me

It must be the worst approximation ever...

Or I'm just really bad at math

m.buettner

Rusher

Yes

it's just that... the taylor series of sin(x). which is just an infinite polynomial, which we truncate to compute it in finite time. but any finite polynomial will shoot off to infinity at some point, right?

Right

m.buettner

have you seen this graph before? that's what happens if you only take the first two terms.

you can take more terms to include more of the maxima/minima, but at some point it has to shoot off

well I need to head off in a bit, so I'll just look for further comments tonight or tomorrow

Quincunx

@m.buettner The trick is that you take a number of terms, then use the fact that sin/cos is periodic to compute it in the most accurate location.

m.buettner

@Quincunx yes, but as Geobits mentioned this is not specified and there is no example clarifying this.

or maybe there is, wait

Rusher

@m.buettner This answer looks like it got your 10^37 repl.it/Sji

run and then type in 90 50

m.buettner

in fact, there is one example that shows he doesn't truncate (the 6.54).

SyntaxError: unexpected EOF while parsing

' 90 50
-1.4213558317646852e+37'

Did you click the run button and then type '90 50' in the terminal?

m.buettner

yeah

I believe you though

the problem is

this doesn't have 8 digits of accuracy

it has 8 digits of precision

like, the result is correct. but the OP wanted to have 8 digits after the actual decimal point

Rusher

Oooooh... I see what you mean now

-1.4213558317646852e+37 I suppose has zero digits after the decimal when expanded

m.buettner

yeah, it's IEEE-754 floating point so there are no more than 15 significant decimal places

Rusher

I have nothing to add to your comment on the post. Hopefully he'll fix it. I don't want to close vote yet, but technically it's unclear.

Visual Studio lost intellisense at 9:00 this morning and I have been happily plugging along not knowing if what I'm writing even works or not

And I'm too lazy to restart it

So I wrote a solution to this:

A: Proposed Question Sandbox - Mark XII

Game similar to the Fifteen Puzzle Because I may factor in "date of solution posted" as a tiebreaker, I don't want to say the exact rules in the sandbox... but the exact rules aren't the reason I'm putting this in the sandbox. Basically, the challenge will be to "solve the given puzzle(s)" in t...

With little optimization it takes like 2 seconds to populate the solution Cayley graph and then spits out the answer nearly instantaneously

So maybe speed is not the way to go

Geobits

Golf it?

durron597

Yeah, that's what I'm thinking

and when i say the cayley graph i mean the optimal one

my prog is just dumb BFS

Geobits

Nice. Nothing like finding out your carefully crafted puzzle isn't as hard as you thought :)

Hello Goodbye
