Husoski: SubZeRoy9 Nobody's answered in over an hour, so maybe you're not interested anymore...but a small if statement will work for Mars Lander 1. Think about controlling your maximum downward speed (see the problem statement).

eulerscheZahl: "proper way", how do you define that. there are search algorithms used too. but that's more interesting for the optim version of mars lander

VizGhar: If "big if statement" solves the problem and you even get those economical achievements, then if statement is way to go for sure

jacek: happy Caturday

NewCoder09: can anyone help me with mars lander episode 2?

VizGhar: One hour and still no question asked :P

jacek: :upside_down:

Default avatar.png weebiss: oh hi

Default avatar.png weebiss: hii

Default avatar.png weebiss: anyone??

Default avatar.png Kokoz: hello :)

Default avatar.png weebiss: hi

vaeng: Is there a way to use Fortran in codingame?

Default avatar.png Kokoz: I dont know what Fortran is :/

Default avatar.png weebiss: Whats that

vaeng: A pretty old programming language that is used a lot for scientific programming

Default avatar.png weebiss: Ahh i see

vaeng: Weather forecast, fluid simulation, ...

Default avatar.png weebiss: :thinking:

Default avatar.png weebiss: ok

jacek: you can make a request on forum to add this futuristic language

Westicles: vaeng, you can get to it through bash but otherwise no

HoneyGlazedGherkinsEggTartare: Fortran implementations are often faster than C++ implementations.

Westicles: it is already installed, it comes free with g++. should be easy for them to add

HoneyGlazedGherkinsEggTartare: https://ntrs.nasa.gov/api/citations/20180000413/downloads/20180000413.pdf

Westicles: how do you figure out if you should score or block in counting tictactoe?

Default avatar.png weebiss: hii im back

jacek: Westicles do the mirror thing and youre good to go

Westicles: what's the mirror thing?

jacek: https://forum.codingame.com/t/community-puzzle-counting-tictactoe/192910/7

Westicles: hmmm, well drawing every game doesn't seem to be a good strategy to get to wood1

eulerscheZahl: funny that it still hasn't been dealt with

jacek: :rage:

jacek: so simple https://img-9gag-fun.9cache.com/photo/aOQPrZN_460svav1.mp4

Huy31: https://www.codingame.com/clashofcode/clash/234689690c57f11c25c416dee403e57ddd47c6e

Huy31: go go go

Uljahn: pls post clash invites on the #clash channel, not here, thanks

Chrimle: I've not received my certification test results. How do I solve this?

Uljahn: DM [CG]Thibaud or wait till monday

VizGhar: somebody asked similar on discord (without response)

jacek: on friday? :thinking:

Uljahn: somebody with same nick

jacek: woah

VizGhar: :grimacing:

Passifi: You know, these are holidays in the civilized world, you wouldn't expect your swedish staff to work on walpurgis night would you ?

VizGhar: Quite offen

Chrimle: What's that supposed to mean? There are plenty of people working on christmas eve, and new years eve etc. Sweden may have a bunch of christian holidays, but not many are actually christians. I won't assume anything about anyone's work schedule. I encounter a problem, I report about a problem. No matter which day it is.

jacek: :+1:

jacek: but theyll probably fix it on monday

Chrimle: Let's hope so! :slight_smile:

VizGhar: And he asked on chat and discord... those are proper channels of communication even during holidays :P Try to call them :S

Chrimle: :sweat_smile:

VizGhar: Heh... I got to gold in mad pod racing even without any steering implementation and looking just one turn ahead...

jacek: you only need -3vel for gold

VizGhar: -3vel?

Uljahn: target - 3*Velocity

VizGhar: First time I see this :D

jacek: oO

Uljahn: rly?

VizGhar: yeah... but to be honest I was too lazy to search through whole forum

VizGhar: Bunch of guys unable to read inputs :|

VizGhar: for legend it is GA/SA/NN ?

jacek: GA/SA

jacek: but probably some bunch of ifs is sufficient

jacek: NN is for the top of the tops

VizGhar: I can't do NNs :) I'm too lazy for this and not very confident

VizGhar: * not confident at all

VizGhar: With SA I'm always struggling with initial temperature, if you guys have any resources on that

jacek: i never done SA

Uljahn: guess your GA in the search race has some SA flavor

VizGhar: Understandable... I want to try it. It is much faster then GA but boy it's random :P

jacek: SA flavor?

Uljahn: like decreasing mutation range

jacek: oh

Uljahn: it's basically an analogy of SA temperature

jacek: i just dont know anything about SA sane hyperparameteres

Uljahn: VizGhar: SA is random, but not so random as MC, i think SA and GA are just trying to guide randomness

Murat_Eroglu: Excuse my ignorance but what is SA and MC ?

jacek: simulated annealing. monte carlo

Murat_Eroglu: Thanks

VizGhar: I'll have to create my own pit for testing parameters :D Is brutaltester helpful in any way here?

VizGhar: I've used it once and It was a bit painful

VizGhar: BTW explain to me the "target - 3*Velocity" again

speed = distancefromtarget -3*velocity?

VizGhar: (I'm not thinking right now)

jacek: target = target checkpoint - 3 * your pod velocity

HoneyGlazedGherkinsEggTartare: go clash

CodiNaruto: hey, I am trying to get the success in which you have to get 5 upvote on a contribution. Could you look at what I did ? https://www.codingame.com/contribute/view/145357388aea5f97a134ed41372fab3fc575a

VizGhar: cant you just wait day or two? :|

CodiNaruto: of course :)

Mortis_666: bruh i joined a clash and left it, but it doesnt remove me from the clash, drop so much rank :(

Uljahn: VizGhar: https://i.imgur.com/HyCgPxh.png

VizGhar: Uljahn :pray:

VizGhar: It's nice that you don't need physics if you have computational power :D

Uljahn: actually i have some simplified simulation (ignoring collisions) to do some bruteforce above -3Vel heuristic

VizGhar: for opponent prediction?

VizGhar: or for your own?

omylist: may i know where can find people join coding escape for beginner ?

jacek: try discord

omylist: which channel should use ?

jacek: coding-escape

omylist: trying

omylist: and thanks

jacek: :+1:

Sarstan: What's coding escape?

jacek: https://www.codingame.com/cooperate

Sarstan: Oh, I never checked out the cooperate tab, lol.

Default avatar.png JakeXS: how do u get a pro account ?

jacek: i think its for companies only

Default avatar.png JakeXS: ;(

eulerscheZahl: some are free for everyone to play

Default avatar.png ForRest_dev: guys, I am new here so I am a bit confused, where I can start learning some useful staff

Default avatar.png ForRest_dev: I saw there was some kind of a game here or was it just an advertising like this?

jacek: probably this https://www.codingame.com/multiplayer/bot-programming/mad-pod-racing

VizGhar: You won't learn basics here if that's what you are asking...

eulerscheZahl: "where I can start learning some useful staff" Thibaud is the most useful staff member for starters. jupoulton for SDK questions

jacek: and whos the best for banning?

VizGhar: EU ;)

TheRipperJack: guys, im working on a problem. my console output , standart output stream shows the correct answer but it says failure "Found: Nothing".

VizGhar: endline?

TheRipperJack: oh yes thank you

a-Rye: ForRest_dev try Activities -> Learn. Then, try Activities -> Practice -> Easy Puzzles or Activities -> Compete -> Clash of Code

freshskates: anyone here from sunnyvale?

Passifi: Man, in general I like really like coding in c++ but whenever a puzzle has intensive parsing it just becomes a nightmare :scream:

VizGhar: understandable :)

VizGhar: but if you reach hard/veryhard puzzles or bot programming, you will be grateful for c++ again

eulerscheZahl: no, i'll just stick with C#

eulerscheZahl: i'm too stubborn

Passifi: is working with strings better in c# ?

eulerscheZahl: yes, it's easier to code

jacek: ill stick to C char array

Westicles: :taco: BlaiseEbuth

Wontonimo: hey VizGhar , if you are are still around and want to know about the -3v thing, here is the best (and easiest) paper I've found to date that explains why https://w3.cs.jmu.edu/spragunr/CS354_F17/handouts/pid.pdf

Wontonimo: it is the same concept that is used for cruise control in cars, basic auto pilot, and tuning shocks in cars.

Wontonimo: and basic AM radio receiver.

Wontonimo: and a lot more applications

jacek: AM radio receiver :older_man:

Wontonimo: it's also in FM but it's not as obvious, as it is kinda mixed in with the extra complications of frequency modulation

SubZeRoy9: Oh crap. I accidentally registered for the bot programming challenge thinking it was a game mode... I hardly know how to do if statements!

jacek: oh my

Wontonimo: no prob. there is no cost or penalty for not competing SubZeRoy9

Default avatar.png AlexYankouski: is it possible to join just short mode clashes?

jacek: no

AdemDj12: hey

Passifi: Good Evening Good Sir/Ma'am/them

Shadman_Shariar: Hello everyone...

Kaelidian: VizGhar

Kaelidian: MY NEMESIS

Masks: (╯°□°)╯︵ ┻━┻

Default avatar.png __Zaax__: does anyone know how score is calculated in CoC rank ?

jacek: https://en.wikipedia.org/wiki/TrueSkill

Default avatar.png __Zaax__: thx !

ASM_MOV_INT: yes, just join clashes and quit until you find one you like

ytaya: hey

ytaya: how can i know the clash is souther or faster ?

Passifi: if it has a distinct drawling sound to it its southern else its faster

Tommyyy: who likes flutter?

ASM_MOV_INT: short mode, fast mode, reverse mode

ASM_MOV_INT: the mode is listed next to the timer

ASM_MOV_INT: once it starts.... in the top left

ASM_MOV_INT: :wink:

piremsema: hii everyone! what's the deal with clash of code events? are they any different from usual clashes?

elijahstorm: Tommyyy flutter is dope

Default avatar.png puppydytt: Hi everyone! I've got trouble, all tests passing but when i press submit the site says that I have 1 incorrect but I fiexd it. I reloaded page but result still same

Default avatar.png puppydytt: Admins?

ycsvenom: http://chat.codingame.com/pastebin/4fefb8ab-2aac-416b-aa16-8a24e24f17ad

ycsvenom: Thibaud there is [Shortest ,Fastest ,Reverse] modes in CoC ,why don't you add [Performance] mode a mode that will give the player 15 mins as usual but the most optimal and fastest code will win and it's measured in nanoseconds

grahamcracker1234: that would make all interpreted languages obsolete

ycsvenom: it will be a huge upgrade for the platform

ycsvenom: i know but no problem

ycsvenom: like in shortest it made all compiled languages obsolete grahamcracker1234

grahamcracker1234: i suppose that's fair

Default avatar.png puppydytt: The following validators differ from the puzzle test cases to prevent hard coded solutions. This is why you can have some fails here even if all of the tests provided in the IDE have been successfully passed

Default avatar.png puppydytt: what does it mean?

BobLob: Perl and BASH would like to have a word about shortest

BobLob: ( at least in regards to interpreted languages )

ycsvenom: puppydytt there are always n*2 testcases for all problems n visible in the ide and n behind the scene testcases

ycsvenom: if you manage to solve all the n visible ones it didn't mean that you solved the problem it just means that you solved half the problem

ycsvenom: your code should be able to fit all testcases

ycsvenom: to assure that you didn't provide the answers of testcases explicitly

grahamcracker1234: sometimes testcase validators are poorly made tbf

grahamcracker1234: at least on coc ones

ycsvenom: that's very possible don't forget that some human made it

Darleanow: HEY EVERYONE missed y'all

Default avatar.png Gilel: wahoo

Default avatar.png Gilel: :apple:

Default avatar.png ruggedcabbage: @grahamcracker1234 you play some crazy games and your code is near perfect everytime, how many YOE do you have?

grahamcracker1234: haha thanks for the compliments

grahamcracker1234: I started programming when I was 11, but I only started taking it seriously when I was like 13-14 im 20 now so hopefully that explains it

grahamcracker1234: as for ruby, i learned it specifically for coc, but i've fallen in love with it. I probs have maybe a little under a year of experience with it

Ducks404: when you decided to take it seriously, what did you do?
