Lee Graham Purdue Skeptics Society Presentation Part 5

This presentation was given on April 1st of 2008 to members of the Purdue Skeptics' Society. The presenter is Lee Graham, a graduate student in the School of Computer Science at Carleton University in Ottawa Canada.

The presentation is entitled "Darwin's Algorithm: Building Creatures in Simulation". It begins with a brief introduction to some of the main principles underlying the sub-field of artificial intelligence called evolutionary computing (EC). EC problem-solving techniques work in a manner similar to biological evolution, with populations of digital 'organisms', each representing a problem solution, reproducing, mutating, and competing for survival.

As an interesting example showing what EC techniques can do, Lee describes his project which involves the evolution of virtual creature bodies and brains in a simulated physical environment. The software, called 3D Virtual Creature Evolution (3DVCE) is available on Lee's website, linked above.

[Minor Correction: Lee wishes to point out that his comment in the presentation about the lack of use of mutation in genetic programming is, in fact, in error. Mutation is fairly commonly used in genetic programming and involves swapping part of a tree structure with a randomly-generated replacement.]

6th part had been removed from youtube, probably because of the music!

in the beginning it just roled on the ground sideways, like a stick or something that you just roll over the groud,

and in future generations it learned to "roll over" and found out that it could make larger distances in a shorter period of time, but it still was not steady and in the end it evolved these 2 "ears" or "feet" ( depends on how you look at it) to keep it balanced and so the result is the unbeatable rollover worm :-D

[Fromzon]

the worm evolved on my computer ^^

it originally was a giant creature with alot of body parts, and the "worm" you see here, is actually the arm ( or leg ) of that giant creature,

in a particular generation it "decided" to throw away the body and go on with one arm, and this is the result after x generations ( i dont remember how many )

[MrBowelsrelaxed]

How many generations did it take it take to evolve the worm? That's awesome.
