An unofficial home for the advent of code community on programming.dev!

Advent of Code is an annual Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.

We all know and love (!) the leaderboard, but how about a different method?

One can solve a problem with a simple, naive method resulting in a short program and long runtime, or put in lots of explicit optimizations for more code and shorter runtime. (Or if you're really good, a short, fast program!)

I propose the line-second.

Take the number of lines in your program (eg, 42 lines) and the runtime (eg 0.096 seconds). Multiply these together to get a score of 4.032 line-seconds.

A smaller score is a shorter, faster program.

Similarly, (for a particular solver), a larger score is a "harder" problem.

The issue with that and reason why AoC doesnt use that for the leaderboard is they dont have access to the code people write, just the final result

Adding that as an option would mean having something that takes into account differences in base runtimes of code for different languages (e.g. scripting languages taking longer) so that its feasible to code it in anything, and having the ability to execute many different kinds of code which can be a pain to set up (and would mean youre then running arbitrary code unless you sandbox it)

I used that as the way to rank people in [email protected] when I was running that and its been on hiatus for awhile due to the effort needed to run it since I havent had time due to building up things in the instance such as [email protected]

It could work if self reported but then its easy to cheat

Oh sure, it's only for fun - I was thinking of it more of a way to compare my own solutions to different problems.

I didn't notice there was a challenges community! That's awesome. (Maybe a more casual honor-based version where anybody can submit puzzles would be easier? Creating puzzles sounds like fun!)

Yeah ill be editing it and trying to relaunch it in the new year with a different format
