Me too. This is why the foundation I founded and run is called
Hierarchical Systems Research Foundation.

SlugGo is a baby step in the direction of a hierarchical architecture
for playing Go in that it is a top level wrapper that only deals with a
few very high level concepts and it leaves all the lower level stuff to
GNU Go. Much of my thinking is influenced by all the hours I have
put into computer simulations of phase transitions in magnetic
systems and the renormalization group theory that describes that
physical system.

One way of looking at the results of the renormalization theory is
that there is a coupling between the length scales of the problem
that extends over all the scales. I find it very interesting that while
I have tried pretty hard to decouple SlugGo from the GNU Go
internals, many things come up which make it very tempting to
couple this longest whole-board space that SlugGo cares about
with the internal and shorter length scale considerations inside
of GNU Go.


Cheers,
David
