Charles Smith (http://autogeny.org/chsmith.html) built somewhat bigger structures than Hayek, but the two are not directly comparable. I think CS is completely scalable. The key thing that price theory does is to bring global knowledge to bear in such a way that local decisions, made on price info alone, act toward a global optimization. (Nothing magic, it's n-dimensional hill-climbing not unlike backprop. Still, there's 200+ years of mathematical analysis for the taking to evaluate market mechanisms.) > Novamente uses economic ideas in some aspects, but mainly just for > allocation of attention (system > resources) among different internal processes.

Yes and no. It definitely needs a head start and a push in my experiments, i.e. a reasonably well designed system which the market just keeps on track. But in personal experience, it takes the actual brain about 50 years to settle down till it really understands what it's doing :-) > However, I really doubt the brain relies on emergent market dynamics to > enable interoperation of its various components. In the research I did before CS, we did some experiments comparing our rational design algos to the standard, cost-oblivious ones. The rational versions, i.e. algorithms that balanced the computational resources they expected to use against the expected value-added in any given search, typically used half the time to achieve comparable results. They used some fairly brain-cracking incremental statistical modelling, tho, and I hoped to avoid the hard work with the market model :-) Josh ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?list_id=303
