Re: [computer-go] : Topological Invariant?

["Weimin Xiao" <weiminxiao@xxxxxxxxxxx>]

Color symmetric is simple. For a normal game board, not the abstract board,
board rotation and reflection could be preprocessed by a rotational
invariant method.

An abstract game board representation should express the full game board in
a topological invariant fashion.

For the full board, you have things like rotations of the board,
color symmetries, and reflections.

But for subgraphs, you have a lot more...
