my program Augos uses a 3 layer (one hidden)
feed forward network to recognize linkages between
chains, and a 4 layer (two hidden) network
to estimate the territorial value of a point.
Both nets learn with backpropagation.

Input of these nets is a couple of 3*3 vectors,
representing the point to evaluate, and the
sourrounding eight points context.

Each of those 3*3 vectors come from different
arrays that represent an aspect of the board:
Fields of force, strategic value, distance
to the edge, liberties.
