how big grid do I even need to for t hat

this is insane

this says I have to use math

rather than creating a array

#

I have a idea

#

what if while going up or left I calculate the top number of dots

#

but hmm

hazy sinew Dec 18, 2023, 7:23 AM

if i calculate the shoelace inline it works

WHY IS THAT

hazy sinew Dec 20, 2023, 8:41 AM

#

#

is this correct

#

we get the previous inputs from ...

#

the top gate checks if all are high, if so it sends low to the or

#

the bottom gate checks if all are low, if so it sends high to the or, and to the flip flop

#

the xor checks if the previous state and current state changed

#

if it did, it sends high to the nxt

#

if nxt receives high from the xor that means it received a signal from the conj, that signal is in the or gate

rini (rini@wetdry.world)

I've just found out this actually doesnt work at all for the opcodes. everything compiles just fine, except.. its not matching the enum value at all. instead, it's trying to match the function pointer of the variant constructor, which was truncated to a single byte with no warnings whatsoever (okay clippy seems to warn you, but it didnt because it was a macro. it also doesnt explain whats wrong at all: https://rust-lang.github.io/rust-clippy/master/index.html#/cast_enum_constructor)

i really hate rust actually

warped dust Dec 20, 2023, 12:43 PM

#

some_func as usize is perfectly valid

#

it casts the pointer

also listen to clippy itll probably scream if u do smth like this

u can use a breadboard and logic gates to solve today

but because theres 200 trillion iterations and the speed of light is 300million m/s, at 1GHz (60 hours to compute) i can use a max of 30cm of cable

because otherwise itll take longer for the signal to travel than for the button to press at 1ghz

Better example for 2023 21 part 2

.##..#...#.

In part two, being able to assume ||there is a clear path to the edges|| dramatically simplifies the logic needed to solve, so here is a modified example input along with its expected outputs:

@teal mountain what happened

teal mountain Dec 22, 2023, 5:45 AM

#

nothing, i was just slow today Sadge

#

first day in a couple of days i've woken up at 6am for it, was busy for a few days

#

maybe a bit rusty

hazy sinew Dec 22, 2023, 5:46 AM

#

what about day 20 part 2

teal mountain Dec 22, 2023, 5:46 AM

#

oh yeah i just don't feel like doing it

#

i'll do it at some point

#

probably today

hazy sinew Dec 22, 2023, 5:46 AM

theres a cheese

teal mountain Dec 22, 2023, 5:46 AM

what is it

#

idc about spoilers atp

(spoiler it for others tho)

#

this is how ur graph looks

#

||the 4 towers are binary numbers, the arrows that go TO the conj are 1 and the ones that go FROM the conj are 0, the top one with 2 arrows and broadcaster connection is LSB, its odd and the numbers are prime and coprime (they dont have to be but they are)||

#

||the lcm of the numbers is the sol||

teal mountain Dec 22, 2023, 5:49 AM

lol wtf

#

did people realise this when it actually came out or only afterwards

#

that's cracked

hazy sinew Dec 22, 2023, 5:50 AM

teal mountain did people realise this when it actually came out or only afterwards

havent heard of anyone who realized

teal mountain Dec 22, 2023, 5:50 AM

#

you could just do that on paper

hazy sinew Dec 22, 2023, 5:50 AM

#

maybe some electronics engineer did

#

cause its an lfsr and it always has this property no matter what

#

if you sinplify it to just a few gates youll notice

teal mountain Dec 22, 2023, 5:50 AM

#

damn

hazy sinew Dec 22, 2023, 5:51 AM

#

if there was a part 3 it would be heres a huge number, construct an input such that it outputs this number

#

i wouldve had an implementation ready

cuz its just berlekamp massey with custom logic

also you can construct the input using 58 xor gates and 58 flip flops (real ones, not aoc ones)

hazy sinew Dec 22, 2023, 5:53 AM

hazy sinew also you can construct the input using 58 xor gates and 58 flip flops (real ones...

or using 4 lfsr ics

#

but we dont have those

#

and im not gonna build 58 xors and 58 flip flops on a breaboard

and it would take about a week to bruteforce because the speed of light is too low

p1 is easy

since it will take you more than 7 minutes to write the code

waiting 7 minutes is better

hazy sinew Dec 23, 2023, 11:00 AM

yes but i didnt know it was 7 minutes

you can solve today using chinese remainder

@teal mountain

i solved it in kotlin

but using z3

hazy sinew Dec 24, 2023, 2:33 PM

hazy sinew

this didnt work

teal mountain Dec 24, 2023, 2:36 PM

i'm gonna have to do z3 too yeh

#

i feel like there's a mathematical sol to this but i have no idea what it is

hazy sinew Dec 24, 2023, 2:37 PM

#

teal mountain i feel like there's a mathematical sol to this but i have no idea what it is

there is and i tried both versions of it, one of them i posted above (off by 494) and the other just didnt work, i couldnt find any matching prime factors

#

z3 is a math solution too except its just equations and you solve for x y and z by bruteforcing

i think its on purpose cuz last year the leaderboard was taken by ppl using ai

#

and writing scripts that automatically submit anwers from chatgpt's api lol

delicate crane Dec 25, 2023, 10:34 AM

#

I have found chatgpt is utter ass at basically all AOC problems, 2015, 2022, 2023

#

Maybe that's because I only ask it when I am desperate and have been working for multiple hours

warped dust Dec 25, 2023, 10:35 AM

i think it was gpt3 actually

#

chatgpt is dumber

it was working though but maybe its just so many people trying

gpt 4 works on most days besides 20s and part 2s of 15+

as you can see by the leaderboard

day 15 part 1 was solved in like 50 seconds and part 2 in 35 seconds

#

hazy sinew gpt 4 works on most days besides 20s and part 2s of 15+

I asked gpt to troubleshoot my code

(it failed all the times)

Actually I asked copilot which is gpt4 afaik

I wonder if ai will be able to do all of it next year

comparing gpt 3 and 4 there is already insane enough difference

you can do every day both parts of all years with ai if you give it 1 sentence of help

u cant tell me this isnt ai

hazy sinew i mean if #1 is ai that makes no difference because nobody lost points due to it

if everyone loses 1 point it makes no difference

#

i think eric should go the route of https://codingcontest.org

#

they explicitly allow ai but the problems are designed to break it

#

so if you dont know what youre doing ai isnt useful

#

but if you do know how to solve the problem and using ai to write code fast its really good

real hinge Dec 25, 2023, 4:12 PM

hazy sinew they explicitly allow ai but the problems are designed to break it

how do they break the ai tho
