Check out this site:

Let it run overnight, change a few parameters (mutation rate, frequency distribution, number of wheels etc.) and see what kind of weird car you can get. Post pics and scores :D.

Have fun :).

I am not seeing evolution?

On Generation 8, have "evolved" backwards from wheels to polygons that go nowhere.

It depends which ones from the previous generation mated with that roulette part of the algorithm. Some will go backwards and eventually disappear while the ones that continue to reach the distances required will live on. After a while it had 2 wheelers with every single one shaped very much like a motorcycle only the back wheel was the medium sized one and the front wheel was the big one... sort of like a longer penny-farthing. Something like 2 thirds of them were reaching their distances. Very cool.
 
Version 2 is out. More tracks, more options etc. My v1.2 bakkie is stuck @ 549.9 :mad:. Seems to have hit a local optimum with a mutation rate @ 2%. Better crank up the mutation rate, maybe that will help.

EDIT: Ah snap mikeyb beat me to it :p.

Yeah, mine was set with a mutation rate of 1%. I ran it for about 15 hours. Couldn't get past a hill at 534ish :cry:, but at least all my cars in a gerneration could get there.
 
Post pics :D.

Caught this chap, all the good ones look similar.

I ran it for a few hours, 6 wheels max at 25% frequency , mutation at 5%, and hit over 1000 on generation 28.

Once i hit 1000, i put the mutation down to 1%, and it got really boring.

Then my laptop battery died, and the pc hard booted.
 
A thousand? is that the score in brackets or before it. I think the highest score in brackets I had was 1019 or something like that. It is just double the score of the actual terrain covered IIRC.

Score before the brackets.

Using version 2, using the UP and DOWN modifiers, I got to 300 on generation 9.

trying to replicate it now, so you can believe me :)

Sheesh, that's possibly an all time high score.

:p 384 Gen 6, but looks like its stuck there now

Weird how sometimes you think, nah, thats gonna go nowhere and then it beats the previous gen.
 
Mine is also stuck at 384.3 :confused: Why wont they go further? It just stops when it gets that far
 
I think it is a quirk with version 2. Either try the "Hang Ten" or "Big air" terrain in version 2 or version 1.2. So far version 1.2 and Hang ten are the most fun for me.
 
Gah, that sucks, have to start over now :/
Had the perfect four wheeler...
 
mah new champ :wtf:

Looks like this is the max so far for v1.2. Try getting up this hill....
