I thought sl4 was long dead. But it's good to see people discussing ideas.
Let's keep it alive. :)
Now to the topic of discussion, when earlier researchers developed initial
versions of AI programs, they believed small mutations, cross over,
selection of fittest, and reproduction over many generations would ensure
elegant solutions. Most believed the AI would now be a matter of enough
computing power and memory.
It turned out that even after much powerful processors and larger memory,
programs simply ran iterations without showing much anticipated improvement
in the "intelligence" so to speak.
Next generation of researchers were began focusing on Neural networking,
knowledge representation, machine learning and patter recognition. Apart
from these, development of theories like computational complexities helped
to see if at all a solution can be obtained.
You see if you get heartache, you go to doctor of IQ 110, not to
a mathematician of IQ 135.

Genetic algorithms may be stupid. But who designed your brain?
