(physicist here) see lines 5-12 of my solution, where I use some numpy and nested for-loops to generate all 3x3 permutation matrices with signs flipped and determinant +1. There turns out to be exactly 24 of these, and they are the right ones.

[2015 Day 7] [c] Kicked my ass!

Java 25/38 https://github.com/fireduck64/adventofcode/blob/master/2021/24/src/Prob.java This involved a recursive sweep through the model number space while memoizing on the current register values. Basically, after the model number parts are read they don't matter for the recursion so the only state is the register values and the execution line number. So the memoization was able to actually help. Although, to be honest my solution for part 1 only worked because the number was near where I started the search (9s on down) and the part 2 only worked because I guessed (correctly) that the first number was still a nine because I'm on to how much Eric likes to punish us. Execution time around 2 minutes.
