Re: [computer-go] Re: Topological Invariant?

It is true that there are a lot of slightly different graphs,
but I don't know of any better compression. This does get a lot
of compression. This compression
already is so big that it loses game playing information unless
you further annotate it. Yet you seem to be asking for a bigger
compression than this, which is simultaneously still sufficient
to specify game position. I don't believe it exists.
