genetic algorithm car physics (update: version 2!)

update: version 2

hahaha some of the early generations created are fucking hilarious

it seems like the best design will end up being something with two huge wheels that can survive a rollover.

Combines my two favourite activities - proving that Darwin was right and laughing at dumb shit

That is really hypnotic to watch, cheers for the link man !

Closes tab before computer builds skynet....

oh snap, what was that site that you could build vector type creations and get them to walk and apply gravity and force and shit. that website was great...

it's interesting, the cars actually become more aesthetically pleasing over time.

it's not that surprising really. cars are car-shaped because there's not really that many practical shapes to be made for a four (or in this case, two) wheeled vehicle with a low centre of gravity.

now we're getting somewhere. 195.6

208

edit: although it seems to have taken a wrong turn at generation 6

Ever get the feeling youve been cheated. Ive had this running through The Smell of Reeves and Mortimer and a cup of tea, so all in all about 45 mins. So at generation 67 its still spunking out monoliths with spinning tops. Every now and again it flukes a car shape and judging from the graph at about gen 30 its went about 230, but apart from the one freak its constantly been a bit shat.

I actually got emotionally invested

chaos machine forealz dawg

The hill around 227 is pretty difficult to surpass

yeah, i'm on gen 13 and have yet to get past it.

also i know what you mean about emotional investment... every time some improbably shaped fuckup actually gets anywhere, i find myself rooting for the underdog.

So, if you leave this running long enough does it eventually level off or do you start getting next level cars that transcend their corporal forms & become beings of pure energy?

the evolution seems to show a sharp tail-off over generations (in other words the really important stuff happens in the first 5 or 6 gens). this makes perfect sense with regards to random evolution if you think about it.

all it needs is to continuously evaluate its current performance based on wheel position to be vastly faster

if you take a random poly with a set number of vertices and distort it by a certain percentage with each mutation within a single generation - choosing the one that performs best as the progenitor of the next iteration - and with a limit on the amount of deformation allowed (5% the default here), then what i said above makes perfect sense. diminishing returns on each mutation.

maybe i wasn't clear enough.

What does Mutation rate do?

increases the maximum allowed deviation from the parent of the current generation

after a while, they evolve into bicycles..

Set mutations to 100%

Lol my ass off.

I love when a retarded one just gets lucky the way it lands and get quite a good score.

this is awesome
