    Discontinued Advent of Code 2020 (by ednl)

    Thanks to /u/thomasahle for encouraging me to implement axial coordinates, which made it a lot easier. Also thought of a better way to parse the input in one go. And this allowed me to tighten up the grid dimensions. Runs in under a second on a very old laptop, half of which is because of the scipy import ... https://github.com/ednl/aoc2020/blob/main/day24alt2.py

    So, the only sensible thing to do was rewrite HashSet for my own use: link

    That is what I did for my perl solution and that takes less than 1.5 seconds to do both parts.

    I'm also proud that to speed up my thinking through this grid, I literally downloaded the top image on the wikipedia article and rotated it 90 degrees. I knew conceptually that the grid he described was the equivalent to what I was looking at, but thinking through the deltas degrees off was hard, so I made it easier, and checked it in for kicks https://github.com/jackowayed/advent2020/blob/main/24/1920px-Tiling_6_simple.svg.png

    Solutions to the 'Advent of Code' (http://adventofcode.com) programming challenges in Elm (by jwoLondon)

    This was a satisfying one. I love working with hex grids. I used the similar 3-axis hex representation as day 11, 2017 (but rotated by 90 degrees), and the similar unbounded game of life pattern seen on day 17, 2020 and exactly a year ago on day 24 2019.

    Advent of Code (by michaeljgallagher)

    Link Struggled at first on how to implement the hexagonal grid, but after a bit of research stumbled across this. Used complex numbers for the offset coordinates (like in day 12), and then pretty much just copy and pasted my day 17.

    Golang library to manage hexagon grids (by pmcxs)

    Really happy with this solution. Borrowed Hex code from pmcsx/hexgrid which I guess is a lil naughty, but I was pleased with my execution time of around 300ms for Part 2 and around 600us for Part 1. Also pleased with the clarity and brevity of my code.

    Python - again, no ifs, ands, or buts, and only four lines longer than day 17. I'm particularly pleased that, by using complex numbers for the coordinates, navigating the directions can be done with sum.
