About

This is my collection of solutions for Advent of Code challenges. Most of these will be done in Common Lisp. I may go back and do some of them in other languages, too.

Random problems have solutions in other languages. In 2020 I made an effort to solve problems in Ada, which I did through the first half. I’m repeating that effort in 2021 as well as attempting the problems in Rust.

Organization

Each year has its own org file (linked below). From there you can get to my code and write up for each of the problems I’ve solved for that year.
