ABSTRACT
This presentation is about a potential shortcut to artificial intelligence by trading mind-design for world-design using artificial evolution. Evolutionary algorithms are a pump for turning CPU cycles into brain designs. With exponentially increasing CPU cycles while our understanding of intelligence is almost a flat-line, the evolutionary route to AI is a centerpiece of most Kurzweilian singularity scenarios. This talk introduces the Polyworld artificial life simulator as well as results from our ongoing attempt to evolve artificial intelligence and further the Singularity.
Polyworld is the brain child of Apple Computer Distinguished Scientist Larry Yaeger, who remains the primary developer of Polyworld:
Speaker: Virgil Griffith Virgil Griffith is a first year graduate student in Computation and Neural Systems at the California Institute of Technology. On weekdays he studies evolution, computational neuroscience, and artificial life. He did computer security work until his first year of university when his work got him sued for sedition and espionage. He then decided that security was probably not safest field to be in and he turned his life to science.

need more variables in the program if you want inteligent creatures to evolve you need food to come about in a non random way. Maybe come about more like a plant which leads to food growing in cycles, spreading, evolving as well as being able to be over eaten lowering the availablilty of plant food. this would lead to inteligence for finding food and a greater niche for hunters. random food just leads to random foraging
ah man if he weren't afflicted with young-grad-student-thinks-he's -the-shit-syndrome this would be a super awesome presentation. instead it's just awesome :)
The way to view 2) is to realize that it's genes, not organisms that are the unit of replication.
For my genes, it will make sense to inject me with a suicidal impulse to sacrifice myself for X close family members. Where X varies depending on how closely related they are to me. The tradeoff point is where it becomes likely that my sacrifice will cause more copies of my own genes to survive by dying than by living.
So, it's not really altruism - it's gene-level selfishness.
techfixer16888, you got that a little backwards; humans were more alike at the start and became more dissimilar in appearance and culture as they moved into different environments, now, because of modern technology the human species is starting to come back together again.
Most of the so called racial type attributes are superficial and would not have much to add to this program. The different shapes represent different species more than different races.
