masongtxr: what
Westicles: heh heh
hinammmm: do u know a forum of whitehat>
masongtxr: no
masongtxr: answer me please
BlaiseEbuth: To what question?
masongtxr: CSB
masongtxr: wood 3
hinammmm: can someone give me some forum of whitehat?
AlanSpacer: You can find white hats in almost every clothing store
hinammmm: not funny

Lekrkutj: for (let i = a; a <= i >= b; i++) {
Lekrkutj: why this doesnt work
AlanSpacer: you wrote it out too mathematically
AlanSpacer: a <= i && i >= b is probably what you mea
AlanSpacer: n
AlanSpacer: However, that looks wrong anyway
juice0: do you want i to be between a and b?
LemonPi314: a <= i && i <= b
if the answer to juice0's questions is yes
Lekrkutj: yeah i wanted it to be between a and b
Lekrkutj: thanks
Lekrkutj: to much of a mathemician apparently
KpskyVnzt: if you want it btw 'a' and 'b' then use ( i=a; i<=b ; i++)

TobiasA: Nothing hurts more than being 1st in a league and yet still being below the boss
TobiasA: I'd rather be last in a higher league:unamused:
martinpapa69: :broken_heart:
TobiasA: has anyone reached gold with flat MC in uttt so I can know what is possible and what isn't
martinpapa69: why would you do mc in uttt :thinking:
TobiasA: :scream:
martinpapa69: mc is not 1v1 friendly
TobiasA: I wasted my time
martinpapa69: not rly you have a sim i guess
martinpapa69: so you can build an mcts around it
TobiasA: if it isn't 1v1 friendly then where is it used mostly?
martinpapa69: 1 vs env
TobiasA: got it thanks
eulerscheZahl: "has anyone reached gold with flat MC in uttt "
yes, I did
eulerscheZahl: then MCTS for legend
xpman: hi
TobiasA: :0
TobiasA: hi xpman
TobiasA: how did you do it eulerscheZahl
eulerscheZahl: for each first move:
run sequence of fully random moves until the end
eulerscheZahl: repeat as long as there is time
eulerscheZahl: take the first move that gives the most wins
eulerscheZahl: won't get you into legend but good enough to destroy silver
TobiasA: i did that too but it only got me too 1st in silver but still below the bos:disappointed_relieved:
TobiasA: *boss
eulerscheZahl: then you need more sims
TobiasA: how do i get more sims?
eulerscheZahl: i don't even know your current amount
eulerscheZahl: how many rollouts at the start of the game? (at 90ms)
TobiasA: dunno:sweat_smile:
TobiasA: lemme check
TobiasA: do you mean the number of steps to get to a terminal node or number of times that process was performed?
eulerscheZahl: the latter
eulerscheZahl: i'll just put up this number: 5k full rollouts at turn 1 (90ms) with MC will get you to gold easily
TobiasA: 4293
TobiasA: that's what i'm getting
eulerscheZahl: sounds good enough
martinpapa69: fix your sim
TobiasA: it works fine though
TobiasA: guess i have no choice but to use MCTS but the thing is if MCTS gets me to gold but not legend i won't know what else to do
martinpapa69: building an mcts on a buggy code doesnt sound like a good idea
TobiasA: if only i knew what the problem was
sarabelforte: hi
TimothyAlexisVass: Hello sarabelforte
TimothyAlexisVass: How are you?
sarabelforte: im fine thanks im a total beginner in codding
TimothyAlexisVass: Oh
TimothyAlexisVass: Hey guys, how is it possible to have played over 100,000 clashes or even played over 100,000 clashes and have a Score around 10-12?
TimothyAlexisVass: Are there bots in the Clashes? :\
sarabelforte: i dont kow
jacek: TobiasA you can make sims more smart. i.e. make moves that win small board more probable
TimothyAlexisVass: Just read about it and yes, there are bots...

TobiasA: that was what got me from second to first in silver
ProCoder03: I did a Flat MC which performed well in Wood, but when I just simply added the code for 3x3 small boards , I am only in top 100s
TobiasA: but wontonimo said % is very slow
ProCoder03: is it a problem with my sims ??
TobiasA: and i have a lot of %:sweat_smile:
ProCoder03: what do you mean by '%' ??
Netsos: cal
TobiasA: modulus
TobiasA: top 100 of what league?
ProCoder03: bronze
ProCoder03: I tried MCTS now
ProCoder03: top 1000
TobiasA: bruh
TobiasA: that's scary
ProCoder03: the prob is my MCTS does some invalid moves
TobiasA: i guess the problem is from your sim
ProCoder03: yeah ik, I just can't find it
ProCoder03: it seems there is a prob with my Main board class , urgghhh
TobiasA: i feel your struggles
TobiasA: good luck on finding the problem
ProCoder03: performance wise , MCTS is good, I usually get around 4000 rollouts for 1st move with flat MC but i can go up to 8000 rollouts in MCTS
ProCoder03: Thanks :smiley:
TobiasA: time to go modulus hunting:muscle:
TimothyAlexisVass: Have you learned anything yet sara?
Wontonimo: modulus is very slow compared to addition, bit it isn't so bad as to avoid it at all cost. If it makes sense to use it and changing it out for something else doesn't improve sims/turn, use modulus
Wontonimo: if you need to do x%9, do it. if you need to do x%16, try instead x&0b1111
ja_fica: you can avoid using muduls
ja_fica: *modulus
ja_fica: in every number
Wontonimo: example of modulus 9 plz
ja_fica: https://aipuzzles.com/learn/performance
ja_fica: random generator section
ja_fica: using shifts
ja_fica: you can go ahead and implement it in your algorithms, thank me later
jacek: considering number generation is your bottleneck
Wontonimo: that's good for rand
ja_fica: ((number >> 16) * mod) >> 16
ja_fica: using uint32_t
Wontonimo: yeah, i know that trick
ja_fica: it works as long as the number is smaller than 2^16
ja_fica: you can do in 64 bits
ja_fica: ((number >> 32) * mod) >> 32
ja_fica: using uint64_t
Wontonimo: sure, but it doesn't do 32%9
ja_fica: sure it does
Wontonimo: ?
ja_fica:
((32 >> 16) * mod) >> 16
ja_fica: ((32 >> 16) * 9) >> 16
ja_fica: xD maybe im wrong
ja_fica: never tried it
ja_fica: you are rigths, im such a noob
ja_fica: *right
Wontonimo: i really like the random number use that you pointed out. i only learnt that trick recently
Wontonimo: it makes total sense
ja_fica: modulus cant be avoided
ja_fica: it can but will be less efficient
TobiasA: Hi wontonimo
Wontonimo: :wave: hey hey
BlaiseEbuth: :scream:
Wontonimo: sorry TobiasA if I made it sound like modulus is really really bad. It isn't crazy
TobiasA: got it

Maxim251: there is 7 bits
BlaiseEbuth: *that
Kepe55: Why
Kepe55: I like python
BlaiseEbuth: :3
Kepe55: So does anyone know what the problem is in my solution?
BlaiseEbuth: Maxim251 know.
BlaiseEbuth: But you don't listen to him... :(
Kepe55: That was for me?
Kepe55: Wdym with there is 7 bits
BlaiseEbuth: rtfm was also a valid answer though...
BlaiseEbuth: "The input message consists of ASCII characters (7-bit)"
Kepe55: If you print it out though it is a normal string holding a message, not ascii
BlaiseEbuth: :rofl:
BlaiseEbuth: Sorry.
BlaiseEbuth: Do you know what ASCII is?
BlaiseEbuth: (Please don't tell drawing with chars)
Kepe55: Seems like I don't I thought ASCII is the numerical representation of a number, bytes("h", "ascii")[0] would print out 104 for example
Kepe55: of a string*
BlaiseEbuth: of a char*
Kepe55: yh
Kepe55: What they provide isn't a number tho
BlaiseEbuth: In fact it is, since the string is composed of chars, that are stored as numbers. -> Their ASCII representation
Kepe55: Oh, so it's basically saying that the characters in the message are convertable to ascii
Kepe55: That's what I did though in my code
Kepe55: http://chat.codingame.com/pastebin/53256509-f098-499f-832e-c090732dcedc
BlaiseEbuth: Right. But the number you get is encoded on 8 bits.
BlaiseEbuth: And the puzzle use 7 bits numbers.
TimothyAlexisVass: OK Some of the clashes weren't finished, now it registered.
BlaiseEbuth: So that probably cause problems when you count 0 and 1
TimothyAlexisVass: Wish you all a great day/evening/night!
Kepe55: oh
Kepe55: thx
Giovanick03: cool
Giovanick03: I'm 12 going to secondary school

Kepe55: http://chat.codingame.com/pastebin/53256509-f098-499f-832e-c090732dcedc
Kepe55: Im doing the Chuck Norris problem rn
Naknik: im asking for the question
Naknik: oh shu I hated it
Naknik: not messing with that again sorry
Kepe55: It works with single letters but not for multiple ones
Kepe55: like its working for C but not for CC
Kepe55: np
Atduyar: hi
arfelious: hi
Wontonimo: hi new people
Wontonimo: :wave:
michaellan: bonk
Wontonimo: Kepe55, are you still looking for help with chuck norris?
Kepe55: Yep :/
Kepe55: I don't get what's wrong
Kepe55: why it works for single letter strings but not for multiletter ones
Kepe55: Blaise said something about 8 and 7 bit ascii, but i dont get how I should turn 8 bit ascii into 7 bit
Wontonimo: i'm looking at your code
Kepe55: thank you!
Wontonimo: i'd have one function that converts a 7bit number to binary text, so 3 becomes 0000111
Wontonimo: one way of doing that would be : f"{number:#09b}"[2:]
Wontonimo: i'm substituting that in for your getBinaryFromNumber function
Kepe55: wdym? Doesn't my getBinaryFromNumber function do that?
Wontonimo: no
Kepe55: oh
Wontonimo: your function returns 11
Wontonimo: as a number, not a string
Wontonimo: it needs the leading zeros
Kepe55: and by converting it to an int those zeros get lost?
Kepe55: So if I stop turning it into an int it would work?
Wontonimo: yeah
Wontonimo: you have a function getNumberFromString which i think your intention is to concat all the numbers
Wontonimo: but i'd recommend concat'ing all the binary strings like '0000111' and then the next one etc
Wontonimo: getNumberFromString simply becomes
Wontonimo: return "".join( [ getBinaryFromNumber( ord( c ) ) for c in string ] )
Wontonimo: getBinaryFromNumber(ord('h')) --> '1101000'
getBinaryFromNumber(ord('i')) --> '1101001'
Wontonimo: getNumberFromString("hi") --> '11010001101001'
Wontonimo: and the end of your program is simply
gotBinary = getNumberFromString(message)
print(encode(gotBinary))
Kepe55: Wait so I would turn my getNumberFromString into def getNumberFromString(string):
return "".join( [ getBinaryFromNumber( ord( c ) ) for c in string ] )
Wontonimo: http://chat.codingame.com/pastebin/4e69cac3-f4be-4186-9175-d752bf9573ac
Wontonimo: yeah, that's right

Kepe55: am I missing something?
Kepe55: I think I got lost
Wontonimo: This is the problem : "{0:b}".format(number)
use this : f"{number:#09b}"[2:]
Wontonimo: add
assert( getBinaryFromNumber(3) == "0000011" )
Wontonimo: to your code right after getBinaryFromNumber
Wontonimo: to make sure it is calculating correctly
Kepe55: Like this?

Wontonimo: I made some other comments above : about "and the end of your program is simply"
Kepe55: So like this
Kepe55: http://chat.codingame.com/pastebin/cbe7e7bd-43a6-455b-89b6-3163615ca08e
Kepe55: YESS it works!
Wontonimo: :tada:
Kepe55: Thank you so much
Wontonimo: no prob
Wontonimo: i'd like to suggest adding little micro tests for each function, like the assert I shared
Wontonimo: it really helps with debugging and ensuring your code continues to work after refactoring
Kepe55: alr, thanks
Wontonimo: for ultimate tic tac toe I have 1000 lines of code, 400 of which are asserts and similar tests. So about 40% of the code just tests the code.

Wontonimo: use stderr instead of stdout

Maxim251: Omy god, I use first time iterator in codingame :D I never used before, i dont have reason to do that, even, I try not use it. But In that situation what I have now, I see that is easier delete position in array in this same loop.
Maxim251: I hope if in for loop if I delete position in vector, still for loop will iterate to next position as usual
Maxim251: and... Bad idea, Iterator works, but my logic is bad... oh.
jacek: umm dont delete using iterators
jacek: at least, try to do it smartly
Maxim251: problem is that Robot need remember turn in new direction, but when he again go to that place, then is destroyed... Problem is that I know how mapped that place, but I dont know how delete robot when he get to that place.
Maxim251: Happly deleting position using iterator works beatifully, but my logic is bad..
Maxim251: http://chat.codingame.com/pastebin/7b3368b6-f344-40ae-bdf9-a3a625714cf5
Maxim251: this is sample of that function
Maxim251: shortly that means, if robot go to position on map that is not avaible to move, then delete robot
Maxim251: Oh my, I had bug, now I know why code did not work. Thats bug is from that stupid ones
