Default avatar.png tkaetzel: yes

Amogh.R: how can we see the question after submitting in clash of code ?

eulerscheZahl: search for it

eulerscheZahl: it's slow right now, i'm not sure what I broke :/

jrke: where is git repo for the same euler?

Amogh.R: hmm yes i cant access it

Default avatar.png tkaetzel: no

jrke: oh found the repo

Amogh.R: is there any api

Default avatar.png tkaetzel: ok

Amogh.R: its working now

Amogh.R: thank you

Default avatar.png NOTsteve: any help for regex? I can't seem to grasp them...

Default avatar.png NOTsteve: like i feel like i just don't understand them and how to use them

Vigasaurus: I really like personally

Default avatar.png tkaetzel: ok

thanhhv317: Hi everyone, i just build a website, using Angular9, please review it for me at:

Vigasaurus: your cert is revoked

thanhhv317: but i see it's still work

Default avatar.png GharbiWass: it's fluid and ergonomic

Default avatar.png GharbiWass: good bro :point_up_2_tone1:

Default avatar.png GharbiWass: @thanhhv317 :thumbsup:

thanhhv317: thank you bro

jacek: good morning

eulerscheZahl: moin

AntiSquid: morning

Default avatar.png indiehjaerta: nmaps= for else"s

jacek: hm?

Default avatar.png Passifi: anyone knows whether you can save time by replacing iterators with standard for loops ?

Default avatar.png Passifi: by time I mean processing time :)

eulerscheZahl: first you should let us know when programming language you use

Default avatar.png Passifi: oh sorry c++

eulerscheZahl: probably not a big difference then. in doubt you should just measure it

Default avatar.png Passifi: kk thx

Knee-Gears: hey euler!

jacek: dont forget to use #pragma optims

Default avatar.png Passifi: just realized the problem gives me the number of elements so I now hope using arrays instead of vectors gives me enough speed boost :)

jacek: what problem

MSmits: hey jacek, I think you were right about the statistics. Needing a million of games before getting a good idea about what the best moves are

MSmits: my initial guess was correct, but that seems lucky, in hindsight. It fluctuated a lot in between


MSmits: adding steal option was a good idea though

MSmits: move 0 value has been dropping hard, these last day

MSmits: this

MSmits: in other games you dont need so many meta mcts games to figure this out. In Yavalath and uttt it's really obvious, but in connect 4 not so much

Default avatar.png legunen: are you a bot ?

jrke: MS whats your othello's algo?

MSmits: jrke it's mcts with early play out evaluation. So kind of like a mcts with a minimax eval at the end. It's about as strong as an average minimax bot. But some other bots are objectively stronger like jacek and dbdr because they trained their bots locally, producing much stronger eval

MSmits: I'll pm you for details

jrke: hmm

jacek: oh im 3rd in othello :c

jacek: you'll post mortem him for details?

MSmits: nah

MSmits: I don't mind sharing how my bot works btw... but it's pretty basic

MSmits: it's highly optimized, uses the basic mcts with no random rollout (EPT eval) and uses all the features commonly used in othello

MSmits: thats about it

jacek: and i bet avx

MSmits: yeah

MSmits: but no ntuples

MSmits: that is obviously the way to go

MSmits: I should learn how to properly do this one of these days

MSmits: maybe next summer vacation

MSmits: I need to finish my yavalath demo project

MSmits: got the board working, but now i need to port the AI. More work than I thought because it needs to be C#

MSmits: and I am not sure if i can use the same kind of code, which takes half a second to form all the lookup tables. This might be very slow in C#

MSmits: and it will be compiled to webgl

MSmits: oh and pdep/pex wont work i guess

Default avatar.png ArCjLord: how work on flutte here

Default avatar.png ArCjLord: who work on flutter here

Megha.Akash: I have worked on Flutter ArCjLord

VizGhar: I have some small projects in flutter done

VizGhar: So you got your answers, I believe this is not what you were looking for ArCjLord

Default avatar.png zhoubou: gm :)

Default avatar.png zhoubou: Well, it's already day. I overslept it seems :P

eulerscheZahl: smart actually. i consider winter sleep for some years already

Default avatar.png zhoubou: Hehe. We should invent a pill for that

Kitkat260: good morning

Astrobytes: Yes, hibernation would be good. Apparently there is evidence that our ancestors hibernated. That's good enough for me.

Default avatar.png zhoubou: That's very interesting, didn't know that


Astrobytes: If you can't read that one:

eulerscheZahl: enough evidence for me. good night

Astrobytes: :D

Default avatar.png zhoubou: Yeah, first one is paywalled

Kitkat260: hi Astrobytes


Astrobytes: You'll find euler under a pile of sticks, leaves and mud for the next few months :D

Astrobytes: hi Kitkat260.

Default avatar.png zhoubou: Hehe :D

Default avatar.png zhoubou: Another thing climate change affects jeesh

SuperSpartan17: I can taste colors. MMMMMMMMmmmm

SuperSpartan17: Purple's my favorite

eulerscheZahl: synesthesia?

jacek: acid

PatrickMcGinnisII: got the vaccine ;)

jacek: or tasted some toad skin

VizGhar: I just looked around, and I don't want to hear more about that fetish

SuperSpartan17: But it's sooooooo good.

eulerscheZahl: VizGhar btw i had a short look at your Tsuro contribution

VizGhar: uhm?

jacek: oh boy

eulerscheZahl: i think Metro would be a little more interesting (similar idea)

eulerscheZahl: as you have multiple trains where you try to build long routes. not just 1

eulerscheZahl: so the game lasts a little longer and is less random I think

SuperSpartan17: <3

VizGhar: hmm I'll take a look. Not even sure whether I want Tsuro accepted as is.

SuperSpartan17: Butterflies will drink your blood, sweat, and tears.

eulerscheZahl: your comments are very random SuperSpartan17. are you a troll?

jacek: AutomatonNN is he?

AutomatonNN: hey guys i want to be fair i guess i will try to add a solution on github

SuperSpartan17: I haven't been on coding game so long.

SuperSpartan17: And last time I was on no one ever used the world chat

eulerscheZahl: maybe it was long ago before world became the default

eulerscheZahl: we were chatting on #general before

SuperSpartan17: Oh ok

alexei_pc: shut up

eulerscheZahl: mind you language alexei_pc

VizGhar: AutomatonNN kinda like this guy?

AutomatonNN: eulerscheZahl is there a way to see a program to tell what is happening to have a lot of problems wi

VizGhar: eulerscheZahl metro seems to be way to go... but holidays are already over :(

eulerscheZahl: after holidays is before the next holidays

eulerscheZahl: (unless that's during contest, then you have to postpone metro)

Stilgart: AutomatonNN: stop pinging euler and say turtle instead !

VizGhar: (you most probably don't have kids...)

AutomatonNN: eulerscheZahl is the problem with the contest in the chat to do a different one

eulerscheZahl: (╯°□°)╯︵ ┻━┻

Astrobytes: :D

Stilgart: :joy:

Stilgart: at least it tried

dhwajsharma: yo

Default avatar.png ChampionCoder: My, quite a few people online now...

SuperSpartan17: Corn Flakes were invented to prevent masturbation.

VizGhar: you haven't blocked him yet? o.O

BlaiseEbuth: Who need to be blocked ?

freeman42x: testing

reCurse: Alright recess is over

eulerscheZahl: :hammer:

Shiverz: Hey everyone, I just implemented my first contribution to the site and i'd like some feedback. If you guys had the time to check it out and tell me what you think, that'd be great ! Thanks in advance !

eulerscheZahl: a = int(input()) b = int(input()) import calendar print(sum(calendar.isleap(x) for x in range(a, b+1)))

eulerscheZahl: first, what did I win?

BlaiseEbuth: :clap:

darkhorse64: Another Coc designed by and for Python ?

Shiverz: Are you saying its too easy ? :/ Cause i had a fast less than two minutes COC in mind

reCurse: Pretty sure most high-level languages have calendar library

Shiverz: Yup, thats true

reCurse: Clash should be separated from CG like

reCurse: Sorry, daydreaming

darkhorse64: std::chrono::year::is_leap for C++. I did not know that

reCurse: Not exactly a new problem :D

Shiverz: Should I remove it and opt for a more original and potentially harder one?

darkhorse64: Let others review it. Frankly, I have seen much worse material

eulerscheZahl: "no clash is too easy" someone insistent to include this sentence in the rules

philRG: @eulerscheZahl: Python king :clap:

reCurse: import king

eulerscheZahl: please, let's be serious I'm Python king boss

eulerscheZahl: * Python Boss King

darkhorse64: Please no

VizGhar: euler 322 puzzles solved in C#... I'm not gonna ask what you do in your free time o.O

philRG: true :-) my mistake

eulerscheZahl: i'm on CG much longer than you are

eulerscheZahl: and i'm not the one who has 100% puzzle completion

reCurse: Time flies

VizGhar: true but still :)

eulerscheZahl: or had before Freecell at least

darkhorse64: Legend in all multis is the great achievement

eulerscheZahl: and contests since Hypersonic (my first contest)

darkhorse64: Yes, even better

BlaiseEbuth: You're a newbie beside me... But I do nothing but trolling on the chat... :sweat_smile:

eulerscheZahl: the French jacek

BlaiseEbuth: You're a frog btw

reCurse: Still trying to breach legend in trolling :(

philRG: trolling takes time and patience

eulerscheZahl: if you do it too obvious, you'll just get banned

reCurse: Refined trolling ofc

eulerscheZahl: expert level trolling and you can achieve everything. even become president

reCurse: That's not refined trolling...

reCurse: That's bannable trolling

eulerscheZahl: good point

BlaiseEbuth: And if you're sneaky enough you become moderator...

philRG: :joy:

eulerscheZahl: psst, don't tell them

reCurse: Oh you mean the trollling was inside of me all this time??

eulerscheZahl: :runner:

BlaiseEbuth: unleash your inner troll

philRG: i started hypersonic 4 months ago when I began to start understanding the basics in bot programming :-)

**philRG unleashes himself

Stilgart: freecell killed the 100% puzzle completion anyway

eulerscheZahl: i refuse to even try it as long as there is an autoplay feature

eulerscheZahl: did JBM even write a solver himself?

Stilgart: Community success rate: 0%

Default avatar.png JBM: nope, not yet

eulerscheZahl: then how do you know if the tests are solvable in 1s and the puzzle classifies as hard?

Stilgart: I am more motivated by downloading the referee and exploiting what I may find than by solving the puzzle

eulerscheZahl: wait, you didn't even write the constraints

eulerscheZahl: "Try to win before reaching the turn or time limit."

Default avatar.png JBM: well obviously the approvers tested it, so it's all right

Default avatar.png JBM: that's what they're here fore, innit?

eulerscheZahl: we all know how well the approval process works (space maze among my contributions)

Default avatar.png JBM: i place great trust in CG's decisions

Default avatar.png JBM: don't make me doubt now

eulerscheZahl: :rolling_eyes:

BlaiseEbuth: Give that man a moderator badge !

eulerscheZahl: the CG community, a fountain of wisdom

philRG: don't make jpm doubt, that's the rule :)

eulerscheZahl: ok, then i'll just wait for him to solve Freecell

Default avatar.png JBM: i thought you were waiting for manualplay

eulerscheZahl: that too

Stilgart: are forks forbidden now ?

Default avatar.png JBM: so not really "just" :D

eulerscheZahl: usually the creator is supposed to have a working solution when posting a puzzle

eulerscheZahl: they forgot that requirement for SDK contributions

Default avatar.png JBM: who reads those checkboxes anyway

Default avatar.png JBM: (cf approvers)

Default avatar.png JBM: I mean I could have let it in WIP

Default avatar.png JBM: but then you'd have complained I'm raking XP

Default avatar.png JBM: you're almost french by now

reCurse: Ah so that's what it is

eulerscheZahl: the solution is so simple: write a solver ;)

eulerscheZahl: then you would see that autoplay is annoying

Default avatar.png JBM: oh i believe you

Default avatar.png JBM: it's still in my todo, i'm not forgetting it

eulerscheZahl: :+1:

Default avatar.png JBM: after the truly important features of adjusting the icon to match the cards, and the klondike-style game ending

eulerscheZahl: :D

Default avatar.png JBM: about solvability: I'm only issuing one of the 32k "Win95" games

Default avatar.png JBM: so you may probably just compress the solution DB

Default avatar.png JBM: -> I'm confident it's ok

Default avatar.png NOTsteve: anyone have any regex advice? I just can't seem to wrap my head around it


Default avatar.png JBM: "now you've got 2 problems" NOTsteve

BlaiseEbuth: ^:slight_smile:$

Trist3: lvl 30+ omg

Default avatar.png RyanGilbert: lol

Default avatar.png RyanGilbert: How do you become moderator to accept contributions?

Default avatar.png RyanGilbert: is that something u earn or do u have to apply

eulerscheZahl: clash contributions: play 50 clashes

eulerscheZahl: any other type of contribution: reach level 20

eulerscheZahl: only public clashes count for those 50, no private ones

Default avatar.png RyanGilbert: ok thanks

philRG: +25Xp for my first contribution of CoC thks EulerscheZahl :-)

philRG: +50xp for moderation

eulerscheZahl: i don't even know what I should ask first here

eulerscheZahl: why only 25XP and not 250? why thanks me?

eulerscheZahl: and why don't you use tab completion to write my name?

BlaiseEbuth: Cause a coc contrib must not give more than 25xp. Cause you're the one. Cause he don't know that this feature exist.

eulerscheZahl: fuuuuuu***** it happened again

Salted: Hahahahahhaha!

eulerscheZahl: how does the font even change itself?

BlaiseEbuth: :D

BlaiseEbuth: That's a spooky font, your pc is haunted... :scream:

eulerscheZahl: i installed it to create the onitama logo

VizGhar: :D :D :D How'd you fixed it last time? cant remember

Salted: I remember writing pranky programs like programs to do that kinda stuff. That's so funny!

eulerscheZahl: full reinstall of my browser

VizGhar: uninstall font reinstall browser :D

eulerscheZahl: hm, i don't think i'll need that font even again. so just dumping it sounds like a plan

eulerscheZahl: and continue until only 1 is left if it happens again

VizGhar: chrome gor font settings

VizGhar: has

Salted: Just embrace it and learn to love that font. I mean that's how I learned to like coffee.

eulerscheZahl: i tried those font settings, had no effect for me

BlaiseEbuth: Keep comic san ms if you do that.

eulerscheZahl: i still hate coffee

VizGhar: Or go study medicine :) you might find that font appealing later on

Salted: What's your go to alternative to coffee?

eulerscheZahl: sleep

Sakshi_Jain: green tea for low caffeine mode and energy drink for high caffeine mode

VizGhar: white tea or sleep for me. I'm allergic to coffee

Sakshi_Jain: Ooo I recently started with white tea, it's pretty good

Sakshi_Jain: have you tried red tea btw?

VizGhar: Best approach is. "I need some sleep, so I get some sleep"

VizGhar: red? :O

Sakshi_Jain: yess

Sakshi_Jain: its called rooibos

Sakshi_Jain: I have a caffeine free one

Sakshi_Jain: it has an interesting earthy scent and taste

Sakshi_Jain: quite similar to silver tips white tea

Sakshi_Jain: but stronger

Default avatar.png Sivasuriyan: u can try beer.

VizGhar: ah rooibos? drank it but didn't like aroma... maybe not pure rooibos tho

Default avatar.png Sivasuriyan: even u can try briani

Sakshi_Jain: ohh

eulerscheZahl: uninstalling the font worked :)

VizGhar: :thumbsup:

Astrobytes: I told you uninstalling the font worked for me when I had my browser-font issue

Astrobytes: and +1 for rooibos (red tea)

Sakshi_Jain: haha

BlaiseEbuth: :coffe:

Sakshi_Jain: so guys I have a very important coding assessment tomorrow

Sakshi_Jain: any tips?

eulerscheZahl: but uninstalling the browser was faster to test and seemed to work at first

eulerscheZahl: is that just you vs the problem? or live coding with someone watching?

Sakshi_Jain: well it's a proctored coding assessment with 3 problems of varrying difficulties

Sakshi_Jain: My performance will be compared with that of other contestants

eulerscheZahl: stay calm, read the task completely and try not to make any assumptions while skipping a few lines

Sakshi_Jain: ahh, I'll really have to keep that in mind

eulerscheZahl: try to think about corner cases (like integer overflow, division by 0)

Sakshi_Jain: I tend to make that mistake a lot

Sakshi_Jain: good idea

eulerscheZahl: the leap year from earlir already got approved and is on stream not

eulerscheZahl: i like my code more

Default avatar.png skyrocky: pls hepl me

struct: ask the question


eulerscheZahl: let's play bingo with this: first who can cross out all 6 numbers

Astrobytes: how many times you posted that link by now?

Astrobytes: *have you

eulerscheZahl: first i think

Astrobytes: Yeah, just the once for me too.

BlaiseEbuth: We gonna post it as many time as required !

Astrobytes: Damn right.

eulerscheZahl: so i'll cross out (3) on my list

Astrobytes: :D

Default avatar.png JBM: errr... cheat solving is *hard*?!

jacek: hm?

eulerscheZahl: i have no memories about that puzzle

eulerscheZahl: oh, i got bored had a rage quit on that one

eulerscheZahl: solved the "double solved rubiks cube", that looked a bit more challenging

Default avatar.png JBM: well now you should have all the tedious code at the ready

DomiKo: My T-Shirt is finally here!

eulerscheZahl: which one?

Default avatar.png JBM: how did you dress before?

DomiKo: one from FallChallange

DomiKo: JBM I have no idea

DomiKo: and one from HackerCup too

DomiKo: Wooo

reCurse: Eh I completely forgot about that

jacek: so now you just wait for pants

eulerscheZahl: hackercup: never did that, I hate facebook

Stilgart: euler++

Default avatar.png JBM: was more of a "requires FB account" that blocked me

DomiKo: :(

DomiKo: Logo was epic

DomiKo: They removed it :(

DomiKo: (in hackercup)

jacek: oO

eulerscheZahl: that too JBM

eulerscheZahl: i even have 2 codejam tshirt so my standards are pretty low. but no to facebook

eulerscheZahl: both collect a lot of data. but at least google gives you something in return

eulerscheZahl: still: congrats for winning it DomiKo. by what i've heard from others, it's not that easy

DomiKo: hackercup is the easiest one in my opinion

DomiKo: beacuse is really strange

DomiKo: you click submit

DomiKo: and you have 6 minutes

eulerscheZahl: the easiest is the hacktoberfest of course

DomiKo: to upload file with output

jacek: clash difficulty?

eulerscheZahl: sounds like the old codejam format

DomiKo: its shit format

eulerscheZahl: download input, upload output

DomiKo: me with nice CPU

DomiKo: can run a lot of O(n^2) and don't care

DomiKo: 4 minutes runtime

DomiKo: pfff

eulerscheZahl: some even wrote tools to distribute it to several machines

DomiKo: yeah

DomiKo: its like

DomiKo: write any solution

DomiKo: that isn't bruteforce

Default avatar.png NotSpice: Could anyone give me some input on the lost child weekly puzzle? I've used a depth first search and I'm getting values that are too high.

eulerscheZahl: you need BFS

eulerscheZahl: otherwise you find any path

Default avatar.png NotSpice: Alright cool.

Default avatar.png NotSpice: Could you give a rough explanation why breadth is better?

eulerscheZahl: painting time...

eulerscheZahl: DFS can find such a path from top left to bottom right:

jacek: BFS finds shortest paths quickier

eulerscheZahl: it gives you a valid path. but you have no guarantees about the length

Astrobytes: That art skill :heart_eyes:

jacek: :notebook: :soccer: is a place when you can train pathfinding algos

Default avatar.png NotSpice: That makes a ton of sense, thanks for the help!

Default avatar.png Butterfart: how do I debug print

Uljahn: are there any commented lines in your starter code?

Uljahn: debug print syntax should be there

Default avatar.png Butterfart: # Hint: You can use the debug stream to print initialTX and initialTY, if Thor seems not follow your orders.

Default avatar.png Butterfart: but i dont know how to use the debug stream

Uljahn: depends on a language

SPDene: as Uljahn says: look at the comments in the default code

Default avatar.png Butterfart: Just found it sorry

Uljahn: good

Default avatar.png Butterfart: Thanks for your help

jacek: rubber duck to the rescue!


Default avatar.png RyanGilbert: are there prizes for the upcoming cointest

Default avatar.png RyanGilbert: contest*

Astrobytes: For the Spring Challenge? Sure.

Salted: Reaching the top 2% of optimization puzzles for the quest map is a monumental task.

Default avatar.png GriM: So i've found this site is great for practice, but how did you guys actually LEARN?

Default avatar.png GriM: Just start the challenge, and then research until you can solve?

jacek: you need at least some basics

jacek: but yes, start puzzle, read on what puzzle requires and google the things you dont know

Astrobytes: ^ 100% this

Salted: After really struggling through a puzzle, I learn by looking at other people's code after I complete a puzzles. It's especially helpful when learning a new language.

jacek: a mod agrees, so its true

Default avatar.png GriM: I know some. Basic syntax etc.

Westicles: what is this google you speak of?

Westicles: nvm, i looked it up on altavista

jacek: or banged it

Default avatar.png Velicko: hi guys, i was playing code vs zombies few days ago and window with animation just disappeared. I now tried again, and still there is no animation... When i play test, i see that it has passed and became green, but there are also no logs and console output window is empty...

jacek: restart browser?

Default avatar.png Velicko: fixed it.. I had some CORS browser plugin enabled :P


Default avatar.png DeltaRays: HAHAHAHAHA

Default avatar.png DeltaRays: feelsadman

Default avatar.png DeltaRays: I beat some guy by 1 character

Default avatar.png DeltaRays: very funny

Astrobytes: Sidesplitting confirmed.

jacek: hm?

struct: jace k playing clashes?

struct: Do I need to release any game to make you stop?

Westicles: chutes and ladders would be nice...

darkhorse64: We are all waiting for Connect 4

struct: Westicles isnt it just luck?

struct: I dont see how you can code an AI for it

jacek: struct make some clash

Westicles: well, you'd have to replace the dice rolling with something else.

jacek: whats wrong with dice rolling

struct: jace k the game is only dice rolling

struct: nothing else

jacek: just like war card game? no strategy, only random

struct: yeah

struct: there is no strategy

Astrobytes: Replace with FOW

Astrobytes: And no board.

Astrobytes: Or anything in fact.

Astrobytes: Game: Snakes/Chutes and ladders Output: valid move

Westicles: This steganography puzzle has me thinking... maybe all clashes should be copied to a very easy puzzle category

struct: which one»


struct: Puzzle was nice

Default avatar.png RyanGilbert: is everyone onffline rn?

Westicles: mostly, yes

ZzzTRAPzzZ: clash of code scoring is rlly unfair

ZzzTRAPzzZ: it was shortest code, so I made my solution as short as possible in python 3

ZzzTRAPzzZ: this is what I got:

ZzzTRAPzzZ: print(sum(c=="1" for c in bin(int(input()))[2:])%2==1)

ZzzTRAPzzZ: but this would print "True" or "False"

ZzzTRAPzzZ: and the expected answer was "true" or "false"

ZzzTRAPzzZ: and even though I solved the problem perfectly it gave me 0%

ZzzTRAPzzZ: while in languages like java "true" is automatically lowercase

ZzzTRAPzzZ: when it scores shouldn't it not account for the string that's give if it's true/false but the boolean?

Westicles: ZzzTRAPzzZ, I suggest we plan some kind of sit-in for protest

Default avatar.png BattleRobot_c964: :flushed:

Default avatar.png RyanGilbert: L

Default avatar.png RyanGilbert: str(True).lower()

Default avatar.png Sineofxisx: A

Default avatar.png RyanGilbert: sadly

Default avatar.png RyanGilbert: :(

Default avatar.png Sineofxisx: yikes

Default avatar.png RyanGilbert: the thing is

Default avatar.png RyanGilbert: java in golf is like

Default avatar.png RyanGilbert: something the bots would do maybe
