I've completed "Restroom Redoubt" - Day 14 - Advent of Code 2024 #AdventOfCode https://adventofcode.com/2024/day/14
What a cool problem today. I got to use my Grid and Position template classes I made to speed up development. And the solution isn’t easily done with LLMs. In fact you need to step through iterations yourself to find an Easter egg. I did some statistical analysis on each grid iteration to guess where it happens so i don’t have to wait so long. Here’s my solutions. https://github.com/marcus-grant/advent-of-code/tree/main/2024/14

Went into this one thinking I was hot shit because I know basic linear algebra and could use numpy for quick elegant solution. LOL, humbled. Watch out for floating point errors.

Phew!!!!!

That was a tough one until I started over with memories of my #ElectricalEngineers days. I used #convolution because, given the right kernel matrix, you can detect edges, and sides in a 2D grid of features.

Not too bad, just make sure you think about what data structure you use, out of memory errors are a real possibility here.

I've completed "Hoof It" - Day 10 - Advent of Code 2024 #AdventOfCode https://adventofcode.com/2024/day/10

Not too bad, just use a BFS traversal with some helper functions and this problem becomes much easier.

Yesterday was awful, the advent is scaling complexity too quickly. Certainly faster than previous years, even last year which scaled quite quickly. Thankfully this one wasn't too bad using DP.

I won't even hide this one behind a CW,

JUST USE SOME REGEX

You'll thank me later, it's not worth doing this one with explicit string manipulation.

I've completed "Red-Nosed Reports" - Day 2 - Advent of Code 2024 #AdventOfCode https://adventofcode.com/2024/day/2

Should've been an hour or less, but man, I get caught up so easily in not reading some tiny detail about the problem I'm solving. When modifying part 1's solution in part 2, remember a report is "SAFE" if ANY removal of one value in the report results in the report being safe with the same rules as part 1. It doesn't matter which value.

https://news.ycombinator.com/item?id=42028873 Really cool paper on SPANN. A way to use nearest neighbour algorithms to perform insanely fast searches on huge data sets. It stores nearest neighbour positions in tensor space for the data sets in memory and then all the actual content stays on disk. With just 64GB RAM they manage to recall any part of 2.6TB of data on average in just under 1 millisecond

Not too bad, gets especially easy once you realize differentials are involved.

Spoilers for "Wait For It" - Day 6 - Advent of Code 2023

This was one of the easier ones so far. Usually the more math heavy ones take less time because there's less wrangling of complicated data structures.

Just make sure you look at the values for distance travelled for different possible charge times. They follow a pattern, with a maximum. Resemble anything? A parabola perhaps?

Honestly with all the abstract representations of data needed to complete these I think I need to start creating data classes that name things to go faster in these solutions.
