Earlier quoted context omitted.

Seriously. They even copied his text verbatim. The original code didn't mention any license which I don't think means it's a free-for-all. Also, they apparently copied the code before he pushed a bug-fix I emailed him yesterday :)

So do you know what the license is. I'm planning to fork this awesomeness for some other variants, and I'm sure others are thinking about that too.

Best assume that there is no license unless it's posted obviously.

I've been watching "PubNub-World-4" for a while (28 generations, animation is still on). It has a nasty hill to climb that stops all cars at about 160 meters. I saw one almost make it over. So now I don't want to refresh and lose the chance that one might eventually evolve to make it.

Most of the cars seem to be quite similar, though. Also, the one that almost made it over doesn't seem to be marked as the leader so there's no net improvement in the cars. I saw one more, in about Gen 30, almost make it over too (it jumps up and sits on the ledge a while before falling back, as opposed to not getting past the ledge or jumping straight up in the air and falling back down).

Very mesmerizing thing.

We are working on improvements to the Genetic Algorithm! Updates Shortly.

You might be able to further increase performance with parallel.js[1]: [1]: http://adambom.github.io/parallel.js/

This looks like it may work out! Looking into it a bit more.

After some improvements on the multiplayer aspects we are starting to see better generations being created and breading between champions.

I don't think this idea works. All players will very soon have the same top car (or the descendant of the same top car), and get a copy of that car from all other players. This creates a massively inbred mono-population. Not sure what the appropriate fix would be. Import the top car from one random player in each generation?

And yet, isn't having the strongest species the goal of an evolutionary algorithm? Having multiple players do multiple runs (parallelization) and ending up with the same / a similar species sounds like a goal to me.

Perhaps you'd like to see more varied species get comparable end-results, but I think you'll need a more varied obstacle course / 'goals' in that case.
