[FRIAM] recap on Rosen

[Joost Rekveld]

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.
