IM GONNA SAY IT :marseyraging:

>be me, day 16 of AOC

>write a solution to part one that only considers nodes with values > 0

>runs pretty quickly, could be better

>get to part two, considering two players

>:marseyclueless: obviously it is equivalent to a single player playing the game twice and not visiting previously visited nodes, right?

>try solution on test input, doesn't work

>shit, forgot about the case where the players run out of time before reaching the end

>rewrite algorithim for two players (tedious af)

>press run

one eternity later

>shit, guess I need to improve the algorithim

>rewrite the algorithm to use a matrix of distances instead of recomputing the distance each time

>part 1 runs 21x faster :marseywholesome:

>:marseyclueless: surely this is the correct implementation

one eternity later

>what the frick do they want from me

>how could i possibly do this any faster

>wonder if there is a linear time solution i'm missing

>scrawl a page of nonsense with matrices, realize that none of it matters because it would be running slower than my interpretation

:#marseygiveup:

>fine, i'll check the solution thread on rdrama

>see a comment from @ihsoy

I solve part two simply by dfs through the part once, and then if time gets to zero, i restart the dfs.

>wtf, that doesn't work, i already tried that on the test input

>try it on the actual input

>mfw it works

>mfw i wasted hours because the test input was nothing like the actual input

I'M GOING TO KILL YOU SANTA CLAUS!!!!!!!!!!!

A fast AoC day 15 part 2 solution without cheating*

[*] with blatant cheating that would make @Snakes blush

pip install z3-solver

    import z3
    x, y = z3.Ints('x y')
    zs = z3.Solver()
    zs.add(0 <= x, x <= size_limit)
    zs.add(0 <= y, y <= size_limit)
    for it in data:
        zs.add(z3.Abs(x - it.sx) + z3.Abs(y - it.sy) > it.r)
    assert zs.check() == z3.sat
    return zs.model().eval(x * 4000_000 + y).as_long()

Darn, this sounds bad, really bad. Imagine if Twitter was a monopoly.

Yea right like that'll stop them from growing, Elmo.
