The influence and territory functions are directly from GNU Go. We have 
not re-implemented anything that is inside of GNU Go. We add some hooks 
for our communication code, we inspect existing data structures and 
have a master process that implements the higher level orchestration of 
the multiple lookahead paths. The master process gathers results and 
makes the final evaluation. The move based weighting functions that 
multiply the influence and territory values are based upon tanh() 
cubed.

Our work is primarily at the level of the message passing between the 
nodes in the cluster, stuff like the pool manager that assigns 
available cpus, establishing the master slave hierarchy. Go is the 
testbed application for our infrastructure, so we are thrilled that the 
GNU Go folks have made such a great Go engine available. Without a 
public domain Go engine I doubt that I would have even tried this 
project.
