genetic algorithm car physics (update: version 2!)

i feel like i'm watching genetic mistakes try and crawl out of test tubes/petri dishes and fail miserably. awesome.

left it over night. best score is about 320.

the problem with this is you get cars that are very suited to the beginning of the track, but fail miserably later on. and all the cars that would survive the later parts fail on the early parts.

I cranked up the mutation and I love some of the retards I'm getting out of it

this is like the slowest GA ever. looks like the cars reproduce asexually, i.e. it's based solely on mutation?

anyone else started to name them based on their appearance?

No names, but I do find myself mumbling "derrrp" at some of them that has 0 chance of survival (like ones that spawn upside down).

his name was "bugs life".

The first generation are all single-coloured. Later generations use those colours to show you what parts they inherited from the first generation.

gen 42 and i've yet to see any car get past the hill at 200

omg one made to 267 but i wasn't watching

kill me now

ffs

i played around with this yesterday but i was transcoding a video and also streaming to the ps3 and it overheated my box. just screwed around with it a bit more, set the mutation rate to 100%. lol it gets nowhere at all. 25.7 was the highest in 11 generations. just ridiculously stupid designs, love it.

ironically the one that made it the farthest did it all on one wheel, and it was luck alone that propelled it that far.

Breakover Angle Fail.

i haven't seen any recover from a flip.. one almost did but it was not to be.

this is awesome!!

somehow i made 309... but also wasnt watching!

you can compare eachothers distances and all, but only if you realize the tracks are generated random each time you start at generation zero....

watch out for the hill at 200!!!

wait, did you just contradict yourself within the same post there?

only on sundays

*hangs out in the gene-pool*

My best last night was 363, but I missed it too :(

Gen 8 426.6

well i'll be

new version is out. Featuring up to 8 wheels!

you beat me to bumping this thread by 6 minutes!

multiple wheels makes this 100x cooler.

some real possibilities here, i can only imagine what things will look like if left overnight.
