hackyouu: hello world

crazy_ape: ouh

Coding_Aria: hello world

Thorcode: hi world

derjack: good morning

TheBlueBias: 'nin

Thorcode: good morning derjack

TheBlueBias: :(

Thorcode: ?

derjack: :upside_down:

Thorcode: How can i handle all the number in the last line of fax machine?

TheBlueBias: In the inputs?

Thorcode: yep

Thorcode: at the heart there is alot of input and It make me dizzy

TheBlueBias: What language do you use?

Thorcode: Python

TheBlueBias: Well something like: [int(i) for i in input().split()]

TheBlueBias: But that's probably already in the base code.

Thorcode: nope

Thorcode: it just input()

TheBlueBias: Oh. Right.

Thorcode: and in the fifth test case the input so long :(

TheBlueBias: So. I gave this piece of code to you, but you'll have to learn about it. Search "list comprehension"

Thorcode: thanks

Thorcode: there is alot of stuff I didn't know in python :(

TheBlueBias: Do you follow any course?

Thorcode: yep

Thorcode: a course on w3school

TheBlueBias: Well you'll probably learn what's missing soon.

Thorcode: list comprehension doesn't help me

Thorcode: oh I get's it

Thorcode: thanks TheBlueBlas

TheBlueBias: :thumbsup:

Thorcode: alot

Thorcode: Wontonimo have a nice puzzle

TechnoBot: Howdy'

TechnoBot: Hello?

Uljahn: :door:

Thorcode: hi

TheBlueBias: Bonus day on ICPC! \o/

struct: why?

Seii: iza no malagasy ato

struct: English in this chat please

Seii: sorry, can't write english very well

AntiSquid: there is #jp

AntiSquid: although what you wrote doesn't look like a spoken language at all

eulerscheZahl: TheBlueBias my reaction was more like :rage:

struct: I agree euler

struct: its unfair

eulerscheZahl: no I'll ask my boss for an extra day off. still pissed, tell me earlier and I can plan. and be less disappointed when I drop in the last hours

AntiSquid: ah malaysian ? seii, well dont think anyone else here speaks it

struct: Did they give any reason on why they extended the contest?

Seii: sorry everyone

AntiSquid: you should be

derjack: oO

AntiSquid: it was a joke, sir bubbleeyes

eulerscheZahl: no reason. just "The contest duration has been extended to 5 days. The actual finish time is October 14, 2021, 00:00 UTC**"

eulerscheZahl: the video announcement always said 5 days. maybe CF did it wrong in the first place?

eulerscheZahl: and now CG down?

eulerscheZahl: CF*

eulerscheZahl: Oops! Probably Codeforces can't be reached right now or your Internet connection is broken. You can try:

eulerscheZahl: https://codeforces.com/

AntiSquid: ya

AntiSquid: it's down for me too

eulerscheZahl: sounds serious. why not extend it to a full month because of this?

AntiSquid: seen some other contests get randomly extended last minute, makes me wonder is it a "we don't like who's at the top so let's give it another try" sort of thing :D

eulerscheZahl: i predicted tourist, NVAL, T1024 and wleite at the top ranks. only tourist still missing

eulerscheZahl: but last time he also appeared close to the end already. has already submitted but really behind in ranking for now

struct: nval comented on the day added

eulerscheZahl: he's not the only one who ranted

struct: I only saw 2/3 comments

struct: but was on the official contest page

eulerscheZahl: mine was the 4th comment about it

eulerscheZahl: thought the more users write about it, the more likely they see what they did

AntiSquid: i would invite some coworkers to post a rant too if i was angry about it

AntiSquid: 502 Bad Gateway on all pages

TheBlueBias: Yeah. I understand euler. But since I didn't had the time to do a lot, for me it's more a good news...

TheBlueBias: You're participating to ICPC too Squidy?

AntiSquid: who's this guy calling me squidy ?

AntiSquid: no, i looked it though

eulerscheZahl: i would never do that. I always write squiddy with 2 d

huhjo: sussy boy

TheBlueBias: Meh... He doesn't recognize me... :(

Overbed: where do i learn python 3 for free

Overbed: the basics

C26_1: um

C26_1: you can googles for yourself

C26_1: or searching in Youtube

Mundgus: w3scool

Mundgus: geeksforgeeks

Mundgus: for python learning

C26_1: @Mundgus, yes explanatory websites

TheBlueBias: Overbed https://www.letmegooglethat.com/?q=learn+python+basics

Overbed: thanks

C26_1: whoa

TheBlueBias: :3

C26_1: I've never seen a website that's like this

C26_1: Set = contains unique things

Overbed: is hyperskill.org a good website to learn python 3 from?

Overbed: it isnt free but my school can fund me a bit

C26_1: Array/List = contains a lot of things (may including copied things)

Mundgus: If you search paid website, use udemy

Overbed: onlineacademy?

Mundgus: udemy.com

Overbed: thanks

C26_1: @Mundgus, struct (Only in C/C++/C#) = short-words for structure, somethings than contained multiple information about a object

C26_1: @Mundgus, dictionary = one-to-one correspondence of info-checking

C26_1: does that fact true or just simply false

Mundgus: struct can contain functions, not just variables

derjack: in c++ struct is just a class without private stuff

Mundgus: Yep

struct: I think it can still be private

struct: its just public by default

Saber-Tiger: What's up

eulerscheZahl: do you have inheritance for structs?!

eulerscheZahl: i always thought that's the main difference

eulerscheZahl: and for C# structs are value types and not object types

struct: you do have

eulerscheZahl: ok. big difference between C++ and C#. to no surprise

struct: They are exactly the same in c++, the only diference is that struct is public by default and class is private

derjack: trust this guy, he knows a thing or two about structs

derjack: loa has no longer WIP in title, but its still WIP?

eulerscheZahl: no, it's VIP now

kimsejin123: hi

kimsejin123: feel very good

derjack: :tada:

miszu: finished 22nd in cvz. Need. To. Optimize. More

Uljahn: :tada:

miszu: what reasonable algorithm can be used when you have (2000x2000)^30 search space?

eulerscheZahl: got the extra day off. still not happy about codeforces

eulerscheZahl: just bruteforce it miszu

eulerscheZahl: you are exaggerating the search space, it's only (2000x2000 x PI/4)^30

Uljahn: NN or search space discretization i guess

miszu: eulerscheZahl akchually.. it's (PI*1000^2)^30

eulerscheZahl: >>> 1000**2 * math.pi == 2000**2 * math.pi/4 True

eulerscheZahl: even python with possible rounding issues agrees that they are the same

miszu: my trigs sucks then lol. I didn't get how you added a pi/4 at the end

Uljahn: what's possible rounding issues in python? :thinking:

eulerscheZahl: >>> sum([0.1]*10) 0.9999999999999999

eulerscheZahl: case closed

Uljahn: is it python's issue though?

eulerscheZahl: IEEE754

derjack: 0.1 + 0.2 = ???????

miszu: how good CMA-ES is?

eulerscheZahl: how good your English is?

miszu: anyone here used it and was satisfied?

miszu: mmmm... English is 3rd language so not the best :(

eulerscheZahl: sorry, just teasing ;)

miszu: haha that's cool :P

eulerscheZahl: for me it's the 2nd language. I surely write some wrong or even stupid stuff as well

miszu: I want to an english college to learn english properly. Man I struggled because you need to pass an english "exit exam" which is like an 2k word essay about ideas from the author

miszu: went*

karandeeppotato: :grin:

jacek: huh? i thought there was english in canada

miszu: if you live in Quebec it's a bit complicated

miszu: they don't like English much

jacek: who likes them :v

chungangli: Hello, everybody, who can help me?

chungangli: I want to change the account email, but I can't do it.

chungangli: I am using gmail for this account, but I want to use outlook email for it. but I have no way to do it.

DomiKo: miszu I used it for some tasks, and it was pretty good, BUT it really depends

miszu: DomiKo do you have a good reference that explains the algo clearly? All I can find is very mathy equations and I can't make sense of it

miszu: I understand the high level but all the sigma etc. assumes that the reader knows exactly what it means

DomiKo: algo isn't really easy, so I don't know if you can find any explanation without math

miszu: at least they explain the pseudo code the operation

miszu: if not I will continue to search

DomiKo: https://blog.otoro.net/2017/10/29/visual-evolution-strategies/

DomiKo: there you can find some visual effects

DomiKo: that could help

chungangli: Dear DomiKo, could you help me?

DomiKo: about mail change?

chungangli: yes

miszu: thanks DomiKo

DomiKo: right corner, there is a arrow, click it, then go to settings

DomiKo: and in setting in "Login information" you can change email

StarsAreFire: For the https://www.codingame.com/ide/puzzle/aneo Is the distance stated - An integer distance representing the distance of the traffic light from the starting point (in meters). From the very start of the drive or from when you enter the zone?

chungangli: I tried, but it is needed to enter password, but I have no password becasue I am using google login now.

Uljahn: those are the same i guess

Uljahn: StarsAreFire

DomiKo: if you are using google login, you need to get a password

TheBlueBias: chungangli use the "forgot password" option to set a proper password, then you'll be able to change your email

DomiKo: do what TheBlueBias told you

LeeDeffo: i have no idea what im doing right now

TheBlueBias: Well. I have no idea of what you're doing right now, if that rassures you.

chungangli: Thank you, friends, it works well. :)

DomiKo: nice

TheBlueBias: :tada:

TimothyAlexisVass: Sometimes when people reverse their thinking, they move sideways without looking at the backside underneath their own position.

jacek: ~paulo coelho

miszu: DomiKo lol in the page: "CMA-ES is my algorithm of choice when the search space is less than a thousand parameters. I found it still usable up to ~ 10K parameters if I’m willing to be patient." cvz: *laughs with the billions of search space*

Uljahn: paramters not states

HalfTangible: We're supposed to share our code, right?

Uljahn: no, this is optional

miszu: my bad

miszu: is it possible that CMAES gets stuck in a local optimum given enough time?

DomiKo: enough time is a weird sentence

miszu: enough generations

DomiKo: I'm not 100% sure, but I would say yes.

DomiKo: but with big enough population, it would be really rare

miszu: I will try to give a shot with cvz. At least the simple one not with the integrals and all stuff

jacek: :scream:

miszu: all I need to figure out is how to generate random points from gaussian distribution and how to apply when you want to make a series of moves

miszu: linking mean and std with many moves ahead

miszu: TIME TO CODE CMA-ES!

TheBlueBias: Don't scream.

jacek: madness

TheBlueBias: https://www.youtube.com/watch?v=KwIe_sjKeAY

miszu: jacek you think it's overkill to use that algo?

miszu: glad c++ has a normal_distribution class in std. One problem less

jacek: its alright

TheBlueBias: don't think twice

jacek: but cma-es sounds similar to madness

darkhorse64: Since people started encoding NN brains in UTF16 for CG, sky is the limit, miszu. (100k too)

miszu: cmaes is not so bad. It's just computing a normal distribution over X% best sample

darkhorse64: :popcorn:

El_Nino619: kys

nikogabro: hello can anyone tell me whats catch in codingame sponsored contest??

TheBlueBias: No. All the interest is to figure it out by yourself.

nikogabro: okay whats your best?

Andrew_Clark: I think I did well

nikogabro: like how much?

Andrew_Clark: 2:07

nikogabro: 207?

Andrew_Clark: the time I took

TheBlueBias: You're not speaking of the same thing...

Andrew_Clark: oh

nikogabro: xd

jacek: oO

miszu: if my parameters are x and y but I simulate 10 moves ahead does that mean I have 20 parameters?

Uljahn: i think yes

Wontonimo: are you talking about a GA miszu ?

Wontonimo: if so, that is how some people implement a GA

Wontonimo: an implementation detail is that on the next game round, you move all the parameters 1 position.

Wontonimo: also, some simulations work better by keeping dx and dy instead of x and y

Uljahn: also you can use complex numbers :smirk:

Wontonimo: oh? tell me more about that

Uljahn: i mean one complex number instead of (x, y) pair

miszu: Wontonimo talking about CMAES

miszu: just understanding the math

miszu: I use dx and dy

miszu: I understahnd you compute mean and sigma for each parameter but I don't get it how the sigma(xy) comes into place

Wontonimo: what is CMAES?

Uljahn: CMA-ES

Uljahn: evolution strategy

Wontonimo: oh, cool. i just learnt something. Thanks

ZarthaxX: guys any recommendation on a cpu?

ZarthaxX: like intel or amd for instance, or a specific model

miszu: amd ryzen are good

miszu: the newest generation\

ipsissimus: ^

ipsissimus: note however, that if you get an amd cpu, youll need a gpu as well, as most amd chips dont have integrated basic graphics like intel

ipsissimus: unless thats changed recently

ipsissimus: *shrug

ZarthaxX: no problem about that

struct: price range ZarthaxX?

jacek: integrated gpu is crap

ZarthaxX: have a gpu, just wanted to know what cpu is good for programming purposes and i guess a bit of gaming

ZarthaxX: struct ehhh hard to tell with the coin conversion hehe

ZarthaxX: i was looking at i7 11gen for exmaple that is 330$

ZarthaxX: accesible here

ipsissimus: no more than a 4 core id say. no need to go crazy with threadripper or anything if you not trying to do some blender rendering etc

ZarthaxX: okey

jacek: but if you ml stuff, the more cores the merrier

ipsissimus: yeah

ZarthaxX: that's something i was worried about

ZarthaxX: if i plan to do data science stuff

ZarthaxX: ML etc

ZarthaxX: would be nice to have 8 cores 16 threads?

ipsissimus: sure, if youre looking for max cores though, i think amd is best bang for buck at the moment

jacek: thats why i have amd. 16 threads

ipsissimus: intel been slacking for like 5 years now

struct: the 11700k has avx512

ipsissimus: thats a over clockable chip i believe

struct: you can even go for the kf

struct: which doesnt have the integrated gpu

ipsissimus: yeah dont pay for stuff you dont need

ZarthaxX: well in argentina the version without F is cheaper than the one with F haha

ZarthaxX: but as you are saying, intel has been kind of bad in last few years, but i didnt know if the i7 11gen was different

ZarthaxX: or the i7 10gen

ipsissimus: i have a great basic system ryzen 3600X and rx 580. does the job and gives me 1080p 60fps which im happy with.

struct: I think the 11th gen is fine

ipsissimus: was around 800 bucks total build

ZarthaxX: avx512 thingy is interesting but i think useless struct haha

ZarthaxX: tempting tho :(

ZarthaxX: nice ipsissimus

struct: Whats the 10850k / kf price there?

struct: its 10th gen though

struct: but 10 cores

ZarthaxX: an equal option in terms of money for i7 11 gen was the ryzen 7 3700x

ipsissimus: hyperthreaded?

ZarthaxX: mmm lemme checj

struct: yes ipsissimus

ipsissimus: i think x variants of ryzen chips are worth it for your use cases

ipsissimus: ryzen just so good for an chip class

ipsissimus: amd went hamm

struct: it depends on the country you live in mostly

ZarthaxX: i9 10850k is like 1/5 more than the i7 11700

struct: On some countries theres barely any difference in price

struct: ah ok

ZarthaxX: ipsissimus you think so? okey..

ipsissimus: ye but in US i think intel overpriced

ZarthaxX: i have seen reviews everywhere recommending amd tbh

ZarthaxX: but i didnt know if anything changed now with this 11gen

ipsissimus: or maybe ryzen underpriced idk

ZarthaxX: ryzen here seems to be above intel in terms of price now

struct: yeap thats what I mean

ipsissimus: ye that demand for a superior product :O

ZarthaxX: ryzen 7 3700x is equal in price to i7 11700, has same cores and threads

ipsissimus: but i think nows a bad time for chip buying no?

struct: but 2nd gen

ipsissimus: what with semiconductor shortage

ipsissimus: ?

ZarthaxX: according to this page tho i7 11gen is better https://cpu.userbenchmark.com/Compare/Intel-Core-i7-11700-vs-AMD-Ryzen-7-3700X/m1450761vs4043

struct: also new cpus coming soon I think

ZarthaxX: but that page says the i7 11gen is better and later on every page says ryzen is better

ZarthaxX: :(

miszu: ryzen 5900 is very powerful

struct: I doubt the 2nd gen ryzen is better than the intel 11th

miszu: that's the one I will buy once I have an rtx

struct: Maybe in some scenarios

ZarthaxX: uh the 5900 one seems very expensive :8

ZarthaxX: :(

ipsissimus: yeah intel chips arent bad we should be clear. just USUALLY more expensive. and sometimes expensive enough that you can get a better chip from amd for less

ZarthaxX: struct its hard to tell without testing it :sweat:

ZarthaxX: right

ipsissimus: doesnt intel have ARC for benchmark testing?

ZarthaxX: it makes me doubt as i have seen that every page recommends amd because its better at multicore

ZarthaxX: so i dont know if even having 2 cpus with same cores and threads, and a benchmark saying intel one is better, i still shouldnt believe it haha

Babali: Bonjour

MmODeadlySins: Bonjour ;)

ZarthaxX: hey

MmODeadlySins: You'are Welcome :)

ipsissimus: i dont think you can go wrong with ryzen at the moment. unless next gen comes out with crazy new tech

ZarthaxX: okey

struct: hi

TheBlueBias: :french_bread:

ipsissimus: but it may not work out price wise dependent on location

Babali: @MmoDeadlySins ça va gro ?

Astrobytes: #fr guys

TheBlueBias: Baguette

ZarthaxX: ipsissimus thing is i have these 2 cpus at same price, and i didnt know what to pick

ipsissimus: which 2?

ZarthaxX: i mean these https://cpu.userbenchmark.com/Compare/Intel-Core-i7-11700-vs-AMD-Ryzen-7-3700X/m1450761vs4043

Babali: Berret

MmODeadlySins: @babali lol

WisTala: English here thanks

ZarthaxX: and the i7 10700 is a 1/5 cheaper option too for those, dont know if worth

ZarthaxX: https://cpu.userbenchmark.com/Compare/Intel-Core-i7-10700-vs-AMD-Ryzen-7-3700X/4077vs4043

ipsissimus: ryzen 15$ cheaper

ipsissimus: ez choice ;)

ZarthaxX: ignore that

ZarthaxX: here is same price

ZarthaxX: i just wanted to show models and benchmarks, not prices as they dont make any sense when talking in different countries :P

struct: ah here the 3700x is way cheaper

struct: 270 vs 320

ZarthaxX: damn :(

ZarthaxX: maybe they are equal here because people is buying ryzen mostly

ipsissimus: well that says something too no?

ZarthaxX: what thing?

ipsissimus: that everyone buying them up and its driving up the price

ZarthaxX: ah

ipsissimus: and its not like amd spamming marketing like intel does

ZarthaxX: yeah its true

ZarthaxX: well in the benchmark page, the amount of benchmarks for ryzen one is huge

ipsissimus: really though, disappointed in intel. they need to step it up. Competition is good for consumers

ZarthaxX: like 10x and more times intel one

ZarthaxX: yeah :(

ZarthaxX: so, ryzen option is good for programming too?

ZarthaxX: i just dont know how much multicore benefits here

ipsissimus: yeah like I said, ryzen is just a sick with the (zen??) architecture

ZarthaxX: aight

ipsissimus: they really went hamm on this product skew i think

ipsissimus: seen alot of true believers come out because of ryzen

ZarthaxX: good to know

ipsissimus: yeah most people dont know but the only reason amd was in the game with intel owning like 80% market share in the past was that amd had the 64 bit architecture patent, and they licensed it to intel. but with recent products, their market share has soared

ipsissimus: take a look and see for yourself

ZarthaxX: oh nice, will check it out ty :)

ipsissimus: https://hexus.net/business/news/components/147224-amd-briefly-passes-intel-desktop-cpu-market-share/

ZarthaxX: annoying to be in this moment of the year where there is a 50 50 tho haha

ZarthaxX: and with these 11 gen from intel that dont have much time on the market to have a clear judge about them

ipsissimus: yeah but both manufacturers going to have a hard time with supply. so prices going to get raised

ipsissimus: prophecy detected

ZarthaxX: probably haha

struct: I dont know how well 12th gen will do

struct: with multiple diferent cores

struct: like 16 cores but 24 threads

struct: only 8 cores have 2 threads

ipsissimus: likely will be OS dependent i think right? some OSs handle core abstraction better than others

struct: no idea

ipsissimus: i have the other extreme than zarthaxx, i like to do small projects on toasters. really makes you figure out how to be efficient

jacek: like how to fit NN in 100k limit

ipsissimus: ye. tho im trash at programming, i know hardware better cuz im EE. but thats why im here :) to get trashed by my competition and look at their code

TheBlueBias: Toasters are less expensive though.

ipsissimus: thats right. and if you can get it to work on a potato. itll work beautifully on company high end employee issued comps

matez: The clash of code page sometimes does not work: when the clash would start it does not give the coding page and you cannot do anything just became the last player :(

TheBlueBias: Just refresh the page and you'll get the IDE

matez: I will test it...

eulerscheZahl: https://codeforces.com/blog/entry/94906?#comment-850177 reasoning for extending the Huawei contest got downvoted so much that it's hidden by default :D

Astrobytes: " So was it just a bad communication (pun intended) " :D

eulerscheZahl: I couldn't resist to do that edit on my post :P

eulerscheZahl: i'm getting wrong answers now and I can't find my bug

eulerscheZahl: works fine with offline tests. I have no idea how the server cases look like

struct: Do I need to give a solution to every flow?

eulerscheZahl: no

eulerscheZahl: if you do, it would be a perfect score

struct: dont think it would be perfect

struct: Because I could not take the best path

struct: Unless I understood the problem wrong

eulerscheZahl: it's about how many valid paths you can create

eulerscheZahl: the distance is the tie breaking in case of same number of paths. looking at the scoreboard you can completely ignore it

struct: oh I see

struct: thanks

Rich_Engler: When your binary search is one step too slo w><

Rich_Engler: For the most part it works, unless the value being looked for is at one of the extremes...

jacek: batman eh

Rich_Engler: yep

Rich_Engler: 85%

Rich_Engler: I just run out of time in test 6

os-moussao: Test 2 didn't make sense for me, if the ball in (0, 0) went the the hole in (2, 1) it would be already 3 moves, yet the ball can is only make 2 moves????!!!!!!!

os-moussao: what do you think guys?

LisaLISA: HI

struct: os-moussao which puzzle?

derzinek: Hello guys. I'm new here and I need some help. Trying to solve chuck norris. Can't pass third test. ASCII for % char is 37 and binary for 37 is 100101. When I encode it result is: 0 0 00 00 0 0 00 0 0 0. My code works correctly but the test says it's 00 0 0 0 00 00 0 0 00 0 0 0. Why?

struct: Needs to be 7 bit binary

struct: so 100101

struct: would become 0100101

derzinek: I think I missed that part. Thank you so much struct.

struct: it needs leading 0's

struct: np

struct: leading or trailing

struct: i cant remember the right word

derzinek: "i cant remember the right word" never mind, I'm not so good at English :))

struct: basicly you need 0's on the left until you have 7 bits

struct: :p

jacek: أوه حقا

jacek: ‮oh really

jacek: Automaton2000 what do you think of this ‮

Automaton2000: i make a new one

Rich_Engler: Trying to solve batman ep1. I don't really see how I can optimize the code further. All tasts pass except for 6 where I am one move too slow

struct: seems like an infinite loop

struct: batman doesnt really require you to optimize the code

struct: ah

struct: one move too slow

struct: sorry

struct: I read it wrong

lolimagine: I GOT

lolimagine: unbanned!!!

Kitis: lol

Astrobytes: let's see how long that lasts . . .

Chrisidris21: ayy

Chrisidris21: rookie lua coder

jacek: beautiful https://i.imgur.com/kH0oSAK.png

2ReGul4r: Hey can someone explain me how I can approve contributions? I got 50+ games of clash of code, but I still cant do it :(

jacek: shouldnt it be more?

2ReGul4r: it says: Any player who has played more than 50 clashes has approver rights.

jacek: so you have 50 or 51 games played

2ReGul4r: i got 51

jacek: maybe it takes time to acknowledge, i.e. the ranking calculation is done once per day

struct: search racer jacek?

2ReGul4r: yeah thats the only tought I had why it would work

jacek: struct eeyup

jacek: i though id try nn there before trying in csb

struct: nice

struct: how many different moves do you allow?

jacek: for GA every move

jacek: -18..18 and 0..200

struct: but this wont be for the NN right?

struct: wont be the same

struct:

Westicles: only 49 clashes

Westicles: you have to look on the leaderboard

jacek: yeah, id probably quantify for starters

jacek: at first im gonna do supervised based on moves from GA

Astrobytes: Quantize you mean?

jacek: quack

ja_fica: I'm having an hard time to convert an array of 128*128 float values to fit in 100k size code

Astrobytes: I was asking seriously

struct: ja_fica do you use 32 bit float?

ja_fica: I do, but I can discard the last 16 bits

ja_fica: and the remaining of the mantissa

ja_fica: *and keep

struct: if its 16 you can use special chars

struct: I think

struct: the cg editor counts chars not bytes

struct: so you can use 4 bytes chars

MSmits: some chars are counted as 2 chars.

ja_fica: the problem is that \0 and \n characters exist

MSmits: (or something)

MSmits: ja_fica let me check how i do it.

struct: I never did this before so I dont really know the details

ja_fica: im having trouble in \0 and \n

MSmits: ja_fica I skip a few characters

MSmits: http://chat.codingame.com/pastebin/233c8046-51fc-4c1c-91b6-feb96730ec86

MSmits: I start at 'a' + 95 to skip most of the control characters

MSmits: and then there are 2 more of those in the 8k range, i also skip

MSmits: stay below 50k or so and you should be safe

MSmits: I only use 14 bit from a unicode character myself, but 15 bit should be safe

MSmits: it's just a bit annoying decoding it, because you have to be careful about how to do the -2 for results higher than 8232

jacek: welp i use 1 weight - 1 character

MSmits: yeah but how do you avoid those control characters?

MSmits: have you just been lucky not hitting them accidentally?

jacek: lower resolution

MSmits: dont know what that means

jacek: + its somewhat homemade ugly solution

MSmits: ok so you skip the bad characters?

MSmits: like this one:

jacek: http://chat.codingame.com/pastebin/c757cb95-b960-477c-b57e-7e3c79517ac7

MSmits: https://www.codetable.net/decimal/8232

MSmits: mmh not sure i understand that completely, but are you just skipping way more characters than you need to?

jacek: probably. here the 'resolution' is 1/3000.0, enough for most purposes

MSmits: yeah but i am not worried about the accuracy of it

MSmits: i am worried about it converting to unicode 8232 which is a line separator

MSmits: thats what ja_fica was talking about

ja_fica: Too complex for me to get it right was

ja_fica: *way

jacek: unicode 8232?

MSmits: ja_fica it's not too hard, if you start at a + 95 and skip 8232 and 8233

jacek: i just care it will not exceed 50000 something

MSmits: this one jacek: https://www.codetable.net/decimal/8232

MSmits: it makes your string go to the next line when you paste it

ja_fica: yes

jacek: i never encountered it then

MSmits: i only did recently

MSmits: (my book got big)

jacek: and the visualiser is done somewhat :tada: https://streamable.com/37v53b

MSmits: that looks cool

ja_fica: MSmits, with your code, I cant print the characters

ja_fica: they get implicit converted to %255

MSmits: no, the function is bigger, but it's C# code, so i dont know if it'll help you

MSmits: this is just the part that skips the bad unicode chars

MSmits: also i dont do floats (yet)

ja_fica: I can do C# as well

MSmits: ok i'll share the code, but its complicated

ja_fica: Well Im not worried about floats

ja_fica: I can use union to integer

MSmits: http://chat.codingame.com/pastebin/9ff1a15c-a645-42be-b495-5d98e582d263

ja_fica: thanks, I'm having this problem at a long time ago

MSmits: I use 6 bits per yavalath move

MSmits: since a character holds 14 bits, the moves are sort of split between different unicode chars

MSmits: the bitindex is where in the current number I am at

MSmits: and the bitnumber is the number for that character

MSmits: this will eventually become a unicode char

ja_fica: thats genius

ja_fica: Thats exacly what I tried to do

MSmits: thanks, i use different systems for different games

MSmits: in bandas i put 10 moves in 1 char =)

MSmits: 10 solved states i mean

ja_fica: but can't we make 14 bits of info into a single char?

MSmits: yeah

MSmits: so a solved state is like 1.5 bits :)

MSmits: W/L/D

MSmits: thats less than 2 bits

MSmits: I do a ternary representation here

MSmits: 3^10 fits in 1 unicode char

MSmits: so you can fit 10 WLDs in 1 char

MSmits: but for Yavalath it's just 2 moves and a little extra, because it's an opening book

ja_fica: Im a litle confused how to use it for 14 bits but I'm definitely use C#, thanks a lot

MSmits: it's easy. First move fits in bit 0-5 of first char, Second move fits in 6-11 of first char, Third move fits in 12-13 of first char and 0-3 of second

MSmits: thats if you use 14 bit, but i could have used 15

MSmits: it's just messy to code, you're going to make bugs. But the concept is easy

MSmits: that list of integers i feed in, all has integers that fit in 6 bits ofc (yavalath has 61 hexes)

Chrisidris21: first time learning lua

Chrisidris21: code

struct: I see that you got 1st again

struct: nice

MSmits: Thanks, I remade the book, it's much bigger now

MSmits: and the bot is new too

MSmits: better TT and pruning

struct: you are doing c4 atm right?

ja_fica: I finnaly got around flatten neural network weigths. Thats my final step to copy weigths. Then all that I'm missing is the training process. Alpha-zero like code its hard to transpose to C++

MSmits: remaking C4 with the same kind of TT. Locally will redo also for meta mcts, I have a great idea for pruning. Maybe i can solve C4 with that

jacek: solve nine men morris

ja_fica: 6x7 is solved in 5seconds

MSmits: I was thinking about the fact that we use only 3 possible options out of 4 with our bitboard representation: Namely empty, p1 played or p2 played. There's not an option for occupying both p1 and p2 bitboards

ja_fica: you can use transposition table with 72 bits

MSmits: so what if I use that for representing parts of the board that can no longer affect the outcome?

MSmits: like cells that can no longer make 4 in a row

MSmits: it does not matter if they are blue or red

ja_fica: static already played positions?

MSmits: yes

MSmits: i can make many many transpositions with that

MSmits: reducing the statespace by a lot

MSmits: so when creating a new state locally, I check the whole board, all useless cells are coloured as this other color

ja_fica: thats happens if you go full minimax

ja_fica: and not MCTS

MSmits: and represented by both p1 and p2 filled

MSmits: this is just for local meta mcts though

MSmits: it will be too slow otherwise

MSmits: drawn or nearly drawn games only solve around 17 or 18 plies before the end. I think i can solve these much sooner with this TT trick

MSmits: or at least re-using the results much more

MSmits: btw, i am not interested in using this to retain/regain nr 1 C4. I could just do that by making a bigger book. I like a shot at solving it

struct: I think ill code my mcts to change the value of the node instead of having the status var to check if its solved

struct: Just to try the avx select again

wizaral: Hello. How to reopen school/job chat if I've closed it?

MSmits: ohh right, i'd be interested to see if you can make it work struct

MSmits: no idea wizaral

struct: i have a version but it doesnt perform better

MSmits: yeah i know, i meant if you make it work better

struct: mainly due to the fact that I need to do some weird stuff to the status var

wizaral: (╯°□°）╯︵ ┻━┻

MSmits: struct you could try it with a game that has no draws

struct: wizaral was it a chatroom?

MSmits: then you can avoid status altogether

MSmits: (just set extreme negative wins or positive wins for solved games)

struct: I still think it wont do much of a difference

wizaral: I used join command and it reopened

MSmits: probably not, but that won't stop you

struct: true, ill try to do something on ICPC first though

MSmits: gz wizaral :)

MSmits: what is this ICPC

struct: https://codeforces.com/contest/1576/problem/A

MSmits: ohh ok, looks cool

MSmits: jacek i was going to solve nine men's morris at some point. Is it up yet?

jacek: its in contributions

MSmits: yeah i know, been there for a long time

struct: I tried playing it vs ludii

MSmits: it's solvable, but requires some trickery

struct: it started smiling at me before I placed all the pieces

struct: :/

MSmits: haha

MSmits: it's exactly the kind of game i like to try and solve so I hope it gets out of contribution soon.

MSmits: you can't fit the whole solved result in a bot as a book, so it's not like you can use it very well ingame

MSmits: but it would be cool to try and train a NN on the solved results

Astrobytes: weren't you going to approve 9mm jacek?

Astrobytes: it only needs one more since eric approved earlier

**Astrobytes killed the chat

TheBlueBias: With a 9mm...

Astrobytes: lol

Astrobytes: that was 9 Mens Morris btw in case anyone didn't catch that

MSmits: naw, we just assumed jacek visits people who submit solved games with a 9mm

MSmits: that jacek, always trolling people

Astrobytes: Hey, Poland isn't *that* wild lol

MSmits: I'm sure Russians think it's the wild west

Astrobytes: I'm not convinced

MSmits: they have wild west themeparks at least :P

Astrobytes: lol, I don't want to know :D

Astrobytes: The image conjured up in the mind upon thinking of that is quite enough

MSmits: hehe ok

Astrobytes: MSmits: Why did Erwin Schrödinger, Paul Dirac and Wolfgang Pauli work in very small garages?

Astrobytes: They were quantum mechanics!

Astrobytes: (before you look it up)

MSmits: oh nice one :)

Astrobytes: A blowfly goes into a bar and asks: "Is that stool taken?"

Astrobytes: (blowfly larvae eat sht)

Astrobytes: Done for today, I'm here all week

MSmits: lol

wegrepdf: hi

Astrobytes: lo

Astrobytes: No no, this version has "William Tell has stretched his bow till it won't stretch No furthermore and/or it may require a change that hasn't come before." after a few rearranged lyrics. I mean they forgot shit all the time lol

Astrobytes: ahhh ffs

Astrobytes: So wish there was a remove message button

Astrobytes: (wrong tab, please ignore the above)

miszu: man get sample from multivariate gaussian is so complicated

Astrobytes: hahaha, fun with stats

miszu: I thought you can plug and play but NOOOO... you have to find a matric A such that A*A^t = Sigma

Astrobytes: It's not a straightforward algorithm

Astrobytes: I mean, I haven't used it, but I've checked it out (the maths at least) and I would make sure you understand the maths first before attempting the algorithm itself

Astrobytes: Are you sure this is a good idea for CvZ?

miszu: cvz would work in theory

miszu: because cma es is good for problems that the reward is much later

miszu: such as cvz

miszu: there are scenarios where you score big points just at the end

Astrobytes: Hm, I get your reasoning

Astrobytes: And good luck with it! Nice placement with the GA btw, you don't just want to fine tune that for a better score?

miszu: I did flat MC

Astrobytes: Aha!

Astrobytes: Told you it was decent

MSmits: Sent you a reply miszu. Going to sleep now

MSmits: gn all !

Astrobytes: gn MSmits

miszu: gn MSmits

miszu: I did flat MC before but I did a mistake

miszu: I chose number between -1000 to 1000

miszu: however rarely you get 1000

miszu: so I fixed thanks to struct and increased to like 2000 so like 50% chance you get 1000

Astrobytes: that's what I meant before about ranges

Astrobytes: Have a higher+lower range than you need and clamp the result to your legal range

Astrobytes: well, not clamp, but take the appropriate value

Astrobytes: You won't go back to trying your RHEA?

miszu: I was too stupid to understand what you meant before :P

miszu: RHEA?

miszu: what's that?

Astrobytes: lol Ah, rolling horizon evolutionary algorithm

Astrobytes: The GA type you were using previously

Astrobytes: GA/EA

miszu: GA I tried but gave me suboptimal results

miszu: but maybe I implemented wrongly

miszu: the crossover part

Astrobytes: That's in its nature but it should be better than flat MC

miszu: I simply took the delta X and delta Y from different parents

Astrobytes: this is a conversation for later for me I'm afraid, I'm going to bed. I think it's worth giving it a go again

miszu: i will

miszu: thanks!

miszu: but need some research about crossover

Astrobytes: there's a lot of different ways, start simple and experiment

Astrobytes: Anyway, I'm out, see ya later :)

miszu: take care!

Thorcode: hi

Wontonimo: hello all

khalis: hi

Wontonimo: hey khalis

Wontonimo: what brings you here?

Wontonimo: not much eh?

Hyperplane: wtw ;]

Wontonimo: hey Hyperplane

Wontonimo: what are you working on?

Westicles: mom called them both to take out the garbage

Wontonimo: it happens

OofButBetter: hello. i am new to this website!

Wontonimo: hey

Wontonimo: how did you find out about it?

Mauprogamer333: can you recommend me a book of algorithms?

OofButBetter: my tutor showed me it

Wontonimo: oh. what have you seen so far?

OofButBetter: only a couple of taks, but i am having lots of fun!

Wontonimo: there is this python cookbook http://bedford-computing.co.uk/learning/wp-content/uploads/2015/10/Python-Cookbook-3rd-Edition.pdf

OofButBetter: *tasks

Wontonimo: what programming language are you interested in

OofButBetter: python

Wontonimo: oh, that link i just sent could be good

OofButBetter: i also write in c++, but mostly python

Wontonimo: and also there is this site to practice some easier puzzles in python https://www.hackinscience.org/exercises/

Wontonimo: once you have the basics like loops, arrays, functions then try some of the puzzles here

Westicles: after you do 50 clashes you can approve my cryptic reverse contribs

Wontonimo: no no plz don't

Wontonimo: oh, i read that wrong

Wontonimo: i thought you said "approve any cryptic reverse contribs"

Wontonimo: please do approve Westicles' reverse contribs

Westicles: heh heh, well no you had it right at first. I watched twitch and they mostly hate them

Wontonimo: my secret is that i don't watch twitch, so I don't know how much people hate my contribs

Westicles: binarysearch seems to be the big thing these days

Wontonimo: what kinds of things have you done with python and c++ so far OofButBetter

OofButBetter: uhh i programmed on those languages and learend to use them but nothing else really

Wontonimo: this is one of the 'intro' puzzles here. check it out and tell me how you do https://www.codingame.com/training/easy/the-descent

Wontonimo: you can pick any programming language you like from the dropdown at the top

OofButBetter: i already did that

Wontonimo: and how did you find it? difficult, easy ?

OofButBetter: pretty easy

OofButBetter: im on temparature right now

Wontonimo: okay, i made this one https://www.codingame.com/training/easy/fax-machine How hard is it?

Wontonimo: okay, do temperatures

Wontonimo: you get more points for it i think

OofButBetter: ill do it after:)

Wontonimo: do you have a math background or physics? If so I can recommend some that have more of a math or physics style to them

OofButBetter: no not really im fine for now

Wontonimo: :thumbsup:

OofButBetter: :ok_hand:

Wontonimo: Westicles, are you working on anything these days?

Wontonimo: when you say binary search is the big thing, on the twitch stream? It's that ... kinda old school ?

Westicles: I hadn't heard of it before. Seems to be about learning algorithms

Wontonimo: binary search learning algorithms? like a decision tree?

Westicles: oh, I meant https://binarysearch.com/

OofButBetter: well i set up my profile pic

Wontonimo: you are mentally unstable

Wontonimo: (tm)

OofButBetter: :joy:

Thorcode: is there any 13 years old boy from US or UK

Thorcode: pls dm me :)

Thorcode: I need something to prepare for SAT

Thorcode: I need more English word in more subject :)

Westicles: they've dumbed down the SAT so much in recent years that almost everyone aces it

Wontonimo: participation badge

Thorcode: ?

Westicles: back in the old days a 1600 meant you got on TV and invited to space camp

Wontonimo: noone watches TV anymore

Wontonimo: so you wouldn't know even if that still happened

Thorcode: or read news

Westicles: people read news 18 hours a day now

Wontonimo: which people? Fox news doesn't count

Westicles: twitter and whatnot

Thorcode: I can solve SAT if I have more word even the SAT is DUMBED down I can't do it if I don't understand the input :)

Wontonimo: what words are you looking to learn?

Westicles: Just concentrate on writing a nice essay about the important of climate change

Thorcode: the math word

Thorcode: like sum plus minus, etc

Westicles: :thinking:

Wontonimo: https://www.khanacademy.org/ has some great word problems

Wontonimo: that are focused on math

Thorcode: thanks

Thorcode: I can write an essay

Thorcode: Thanks Wontinomo

Wontonimo: let me know if that helps

Wontonimo: you are welcome

Westicles: I always get suspicious when the chat log is missing a day. Something big must have gone down yesterday

Wontonimo: :thinking:

Thorcode: Yesterday my chat broken :(

Thorcode: can't connect to the server :<

C26_1: if stockPrice() > stockPrice(1)

C26_1: sorry

C26_1: I'm just type the wrong button

Wontonimo: good night

Wontonimo: :wave:

Thorcode: Night night Wontonimo :)
