As far as I know our neural networks are quite good at mathematics, and that's
not a fuzzy discipline at all. That's to answer your previous message.

Considering the current state of computer chess it is very possible that the
only way to finally demonstrate a real superiority over the world champion (or
the five best human chess players on the planet) will come from something that
will have something to do with neural networks.

I see the current approach at best to be able to demonstrate that it is on par
with the best human player. I don't know what you think, but I consider this to
be extremely humiliating for computer science, given the efforts and resources
that have been spent on it.

A well trained brain can be world chess champion, a well trained 386 cannot.
Unless you are extremely optimistic about computer science. :)

Biological neural networks have proven to be so different and nevertheless so
close in computing ability to computers that it is obvious that current
computers have much to learn from them.

So eventually what counts is not the superiority of one approach (Von Neuman
architecture) over the other (neural networks), what counts is that both have
unique skills and it there is probably much to gain from the one that is
currently almost not used at all.

That being said I know how to do well at chess with a Von Neuman architecture,
but I have not idea how to do it with neural networks... :)
