I created this site, if anyone has any questions.

How are you calculating fitness?

dbilenkin5• 15 years ago

The fitness is simply the distance traveled to the right. The DNA is made up of segment lengths, with, joint rotation, joint speed and joint offset (when the joints move relative to the other joints)

Thanks for making it. Very entertaining and almost hypnotizing to watch.

The application freezes for me when I set "population size" to 5, i.e. identical to "simultaneous creatures". Seems to happen rather consistently in Chrome on windows.

Edit: Seems to be able to reproduce the issue in FF as well.

One of the coolest things I've seen on the internet recently! Show this to Richard Dawkins!

Please do continue with work on this site, I'd love to see the underlying algorithms etc. I would like to make a small donation, if you let me know how.

Awesome stuff. You should put the source somewhere :)

I was pleasantly surprised to find you can zoom in/out the canvas.

Nice. Wasn't sure if people would realize that. Unfortunately, this was a project that was abandoned after being about 80% complete due to other stuff getting in the way.

What wasn't implemented then? It seems to mostly work, besides some of the buttons not working correctly.

So your saying that it's like every other software project ever made ;)

So inspiring to see god's hand at work, right in my browser. ;)

As I wrote the code, I could feel his divine influence through my fingers.

Your application is cool. But are we really going to turn this into a religious discussion? Because it's possible to be a Christian without believing that a man in the sky has personally designed each individual creature on earth. The latter is an extremist view which for some reason has become the mainstream in the US.

Pushing the "Evolve" button crashed Mobile Safari. :(

Set "render" to "wire" and try again. That helped on my iPad.

Great project! I'd love to see physical attributes change over time and not just behavior though.
