I took a quick look - 80 page paper - I'll have to put it on my stack for
now. Still plowing through papers from that discussion on CAP (I took time
out to reread Shannon's "The Mathematical Theory of Communication" so I
would be in a better position to understand the relationship of
hyperspheres, ribosomes, and the capacity of molecular mahines - information
theory of binding sites, that sort of thing). But I note this Fontana and
Buss work at first glance seems to be in the spirit of Stuart Kaufman's
autocatalytic cycles. Fontana is associated with the Santa Fe Institute, so
maybe no coincidence...
