This repo contains my solutions for the Advent of
Code 2023 in R.
Here’s my past performance (and this year’s performance, so far):
However, this year is not really about performance, especially not when it comes to completion times. Most of the code in this repo was written using only one hand, because I’m nursing a three-month old baby with the other.
I solved the majority of puzzles in base R. I’ve marked the days where
I used libraries with footnotes.
Follow me on Bluesky!
Here is a table of contents showing you what each day was about, along
with some stats. Completion time refers to the time it took me to
complete the puzzle since release (part 1, and part 2 in brackets), as
tracked on the Advent of Code website. Next is my rank for the puzzle on
that day (part 1 (part 2)), and finally the runtime of my code. It’s a
crude measure of runtime1, where I simply calculate the difference in
Sys.time() at the beginning and the end of part 1, and the beginning
and end of part 2. That means in some occasions, the runtime for part 2
will be much shorter because part of the code needed to solve part 2 was
already run in part 1. Reading in the data (and sometimes, basic
preprocessing that has nothing to do with the puzzle solution) is
excluded from the run time calculations.

I know these stats are basically meaningless for anyone else’s computer, but to put things into perspective, here are my computer stats: Razer Blade 15 Base Model, Intel Core i7-10750H CPU @ 2.60GHz, 259 Mhz, 6 Cores, 12 Logical Processors, 16 GB RAM ↩

POSSIBLE SPOILERS AHEAD! Here, I used the function
mLCM()from the packagenumbers. ↩ -
For part 1, I originally coded up a base
Rversion that takes 1.09 min to run (day23_pt1.Randday23_functions.R). Then, I wrote a second version usingigraph(day23_pt1_v2.R) which is reported here. For part 2, there is only one version usingigraph(day23_pt2.R). ↩ -
Here, I shamelessly used
igraph. ↩
