Hi Ken,
in the context of Rosen's objections to course of mathematics since
pythagoras, in what respect would CPPN's be any better than 'rules
centered agent based modelling' ?
I never heard about CPPN's; it seems interesting, but I can't really
find any examples of something they're better at than 'straight' CA
or neural networks ?
curious,
Joost.
