so what i thought was impossible (deep pit preceding a long steep hit) was actually beaten, but it seems that it gets harder because those types of cars mess up later on

edit:
lol i just watched one car completely flip over and then continue onward

Ah, this remembers me of the year before last year when I took the AI course in my uni.

We had to implement a generic algorithm back then, but none of them was as cool as this lol

I can do one better. I had an entire line of cars who had very rounded, top heavy, roofs because they would flip at the bottom of a very large downhill slope. About 1 in 3 or 4 would do the full flip, just enough to keep the dome top until the trait died off ater 4-5 generations. It was an epic trait.

Let it running overnight, doesn't look like it'll ever get up this hill though

Heh. Screw your raised-midsection designs. My game found a different solution for those spikes that might catch you.

Fly over them with pure speed.

what the hell is up with this regression, some bad front-heavy trait took over while I was asleep last night, ruining my sleek designs.

They all used to look like this:

Would it be possible to add a button to display the best run so far? I noticed that the run cuts off when it reaches the previous best, but still records the rest of the run in the parentheses.

I can't believe I watched this run while eating breakfast. I find it so interesting

I think the parenthesis is the top distance that the current generations cars can get up to, to be considered complete successes, and it's always double of the previous generations top score. When it reaches the number in the parenthesis, it doesn't deem it necessary to keep recording (for some stupid reason) so it restards. Noticed it one time when I restarted, always got confused by that number at first.

I've had a simulation running for two days. The track mine spawned has a very large hill at around a distance of 180. It took over 150 generations before a car spawned that could climb it. I wasn't around to witness it though, and it couldn't recreate that success. Yesterday I got home and saw that there were a bunch of generations around 260-280 that built cars that could climb the hill, and luckily enough the first car I watched after I got home made it up successfully. Turns out, the best cars to get up a hill have slim bodies with a small-medium back wheel and a large front wheel.

But, once again it could never recreate it. I left this morning when it was at generation 490 and there's been no further success.

This is truly mesmerizing to watch, and it makes me think a lot. How does the selection work? What about mutations? What if you could set different mutation rates for various traits? What if you could have more traits than there are? (Number of vertices, number of wheels, spring coefficients...)
I feel like a version 2 is in order. With various modes of selection, user-made tracks, per-generation random tracks and everything I mentioned above. And blackjack. And hookers.

TL should work together to create an advanced version of this tbh. I would help but my programming skills are limited.

the cars in that thing dont really seem to be evolving, every once in a while there will be one that goes a long way, and then the next one ends up being complete shit

It seems that a new version is out, with the ability to up/down vote the individual cars (?) and some additional options.
