when reaching a 100% on a given challenge in a specific programming language, it’d be nice to see how the own solution compares to solutions provided by other users in case of cpu usage, memory usage and execution time for example.
I like the idea, maybe the solo games in “Optimize” should have multiple ranking:
score, for this particular game (like fuel consumption for mars lander)
number of characters
cpu usage
memory usage
…
Also, thus data could be used for blog posts, comparing languages or vm, like http://benchmarksgame.alioth.debian.org, or describe some implementation or algorithm.
Could attract attention, and more players.
