Do we have to see a new variant on this every week? Or every month? It's fun to watch, it's cute, it's cool, but it's getting tedious.

I for one never get tired of this evolutionarily challenged little vehicle. Wee look at the little guy go! Or not as the case may be after 65 generations or so...

Indeed. Those who are interested (such as I) can go to boxcar2d.com themselves. A major technological leap/ton of new features/big milestone would merit a post, but not a slightly improved algorithm.

This version is definitely an improvement, and interesting to watch. I welcome it.

This doesn't actually look like a Genetic Algorithm to me.

What I would expect is that with each generation, the "most fit" car or cars from the previous generation are combined with small mutations, and then "duke it out" in the next generation.

What i'm seeing is that each "generation" includes 20 different vehicles, each of which mutates a little bit. I'm not seeing that much trial and error or different versions of the same "DNA".

It's been running for over an hour now, and they don't seem to be getting any better. How long is it supposed to take?

Wow, this is amazingly fun to watch!

Can we genetically evolve algorithms for genetically evolving cars?

fun toy. suggestion: do it with some fake animals with legs and all

suggestion 2: guide more the mutation to avoid spawning for hours without success
