Thanks for the tip, but I think mine should be doing that right at least. My day 16 took 4.5 hours to run, which was longer than most I think.

i dont fundamentally understand how it can take so long, theoretically a greedy algo makes sense

earnest forge
i dont fundamentally understand how it can take so long, theoretically a greedy ...
Greedy algo is obviously correct for geodes (that's the primary optimisation goal, after all) - but I think it isn't generally correct for any other machine
earnest forge
but when making robots
Take this example: ||Ore robot: 10 ore, clay robot: 11 ore, obsidian robot: 12 ore + 1 clay, geode robot: 13 ore + 1 obsidian||
A greedy approach will obviously get the wrong answer
raven wave
yeah
idk if im sounding dumb but what if it was in reverse
so it considers the most expensive robot first
wait no

Does it specify anywhere that you can't build several robots in one turn? Or is that just supposed to be assumed?
magic oxide
well apparently it doesn't work for the test if u let it be multiple per turn
i guess u kinda infer from "robot factory from your pack"
lunar jackal
The elves: Hmm am I forgetting something
You:
earnest forge
Does it specify anywhere that you can't build several robots in one turn? Or is ...
It tells you that it takes you a minute to build a robot, I'd infer that to mean 2 minutes for two robots i.e. only one per turn
keen trout
Does it specify anywhere that you can't build several robots in one turn? Or is ...
It says you only have 1 robot factory and it takes 1 minute for it to build a robot.

Doing day20 part1, and I'm having trouble. I get expected behaviour with test inputs, but not with actual inputs. I think my problem is ||dealing with values where abs(item) > length - it's throwing my calculations off||.
I think it'd help if I could have some sample data that has some such behaviour, and what the result at each step should be.
Actually, could someone give me the result of each step for the following test data (7 items which aren't part of my inputs), because I think that'd help me figure out how things should behave:
||8, 8, -11, 3, -9, 0, 12|| (edit: or maybe ||8, 7, -11, 3, -7, 0, 12|| )

In Rust (reimplementing in python to see if somehow that chanfes things because I'm desparate and it's easier to communicate on this server) I'm using ||collections::VecDeque|| which is equivalent to python's ||collections.deque||.
For each item, ||find index, then rotate_left index steps (python deque.rotate(index*-1) I think. Then I have two implementations. With one I pop_front (popleft), rotate k steps, then push_front / appendleft. k is abs(n) % (len old xs or len new xs). With the other implementration, I replace the value with None, then do the rotate, then push, then remove the None. First implentation works on sample input but feels buggy, second inplementation doesn't work||
unique osprey
ok this part ||abs(n) % (len old xs or len new xs)|| . Make sure ||the "length" is length after removing the item||

I don't know that the tetris one is 'hard' its more that I just cba with all the boilerplate. But I also havent done it becasue I thought "cba with that" so maybe im missing the nuance of it!
magic oxide
I found it personally difficult because I didn't know how to ||do cycle detection||
at least for robot assembly I knew how to ||dfs from day 16||
silver wyvern
See I havent done 16 or the robot one because ||dfs is new to me and im not 100% on writing somethign that complex yet.||
How would you apply ||dfs to day16 though? Since i think it matters in which order you trigger the valves||
Unless Iโm mixing up ||bfs and dfs||
marble smelt
where do I find the challenges?

compact wasp
nah tetris was fine
torn thorn
but it was self obvious what the trick was
magic oxide
didn't you guys cheese it by ||guessing the cycle was just one cycle of the moves||
torn thorn
||i didn't detect any cycles in the actual jet streams itself, so it would've been a multiple of the length of the jet movements||

covert arrow
||they were in the 2k range I think||
torn thorn
looked at the golf ๐ญ
magic oxide
that's how many moves there were
compact wasp
i see a modulo so it has to be length
magic oxide
the golfs make some assumptions
compact wasp
golfs just have to work on all aoc inputs
magic oxide
about the input
torn thorn
meh
magic oxide
like for yesterday we assume that no monkey had ro__ as their name, and that humn came before root
torn thorn
i have some mixed feelings abt that
covert arrow
we just look at the 6-7 inputs we have and if something is true in all of them, we just assume that it's true for all inputs
compact wasp
common sense applies though
like obviously we aren't just building a dict that maps inputs directly to outputs
magic oxide
another one I remember is day 13
we assume the numbers are from 0 to 10 and that the max nest length is less than 5
torn thorn
lmao
magic oxide
yeah
torn thorn
it might be interesting to see how much it'd add if you didn't assume anything about the input than what was directly stated

it'd break entire solutions
for certain ones
for others it'd just add extra chars
compact wasp
yeah
torn thorn
it'd break entire solutions
i.e.?
magic oxide
day 13
torn thorn
ic
magic oxide
you need empty lists to be negative numbers
but they need to be comparable to each other along their absolute values
so I did nest level-5
if it's greater than 5 it breaks the code
you could do like 99 but it'd break for nest lengths of 100
you'd have to add an entire function to find the max nest length if you wanted to salvage it
compact wasp
day 21 also breaks without certain assumptions
for instance, we assume that ||part 2 is linear||
magic oxide
yeah

oh
torn thorn
||wait oh u mean if there was like root^2 or smth||
compact wasp
||1j * 1j = -1, which would mean that there could be no imaginary part||
magic oxide
||no we mean like if we had (humn related thing)*(humn related thing)||
compact wasp
||without the imag part, we cannot solve for the unknown, because it just disappears||
covert arrow
||normally it would be quadratic but the x^2 term would be lost||
torn thorn
ic
compact wasp
whoever came up with that idea should get a raise frfr
magic oxide
||since any vector isomorphic to R2 works, we don't need the bilinear product that comes with complex, but that also means that we don't have a proper operation for (humn thing)*(humn thing)||
magic oxide
whoever came up with that idea should get a raise frfr
they can get a 25% raise
from 0 to 0
torn thorn
||ok but what if there were multiple monkeys that required the humn node||
and it wasn't linear
compact wasp
||ok but what if there were multiple monkeys that required the humn node||
||as long as it's linear, we're all good||
compact wasp
and it wasn't linear
ok but this was one of the assumptions
without that it just breaks
torn thorn
how would you solve it if it wasn't though
torn thorn
multiple roots though?
compact wasp
pretty sure it's guaranteed to converge on one of them
if it's implemented correctly
torn thorn
how'd it be implemneted?
magic oxide
if it wasn't ||linear||, I probably would've just used my ||rational function class and made a rational function out of the thing, and then found the root||
compact wasp
idk yet
magic oxide
||golf would be difficult tho||

unforunate ๐
magic oxide
||if it wasn't linear it'd be a pain for the input creators as well since they have to guarantee a unique solution or do something else||

magic oxide
||they say just to multiple them all together and use that number ez||

||since if some of the roots have multiplicity > 1 you wouldn't be able to just vieta the answer straight up, so some inputs would be unfair||
