Octavius began in 1999 on my Pentium 166MHz, 32Mb RAM - LOL, yes, I played
around with neural networks on such a machine. I researched the internet
back then and found nothing on Chess and ANNs, so I took it up as a "hobby".
Within my first six months of creating and training Octavius, I recieved
interest from Sao Paul University, University of California, and the Karpov
Chess Institute.

I now have a Pentium 2.4GHz with 1Gb RAM - delicious...

So, over these 4 and a half years I have been training several different
types of neural networks (all using the Octavius program) and the other
day... for the first time EVER... he beat me using ONLY the neural network
(NO material analysis).

I admit - I blundered... but generally, that is how one loses a game of
chess. Nevertheless, Octavius was the victor. I am used to play testing him,
and I am a reasonable player, so my thinking time is about 1 or 2 seconds on
average. Octavius's thinking time is about 5 seconds (it's the training that
takes a long time!).

Here are the current ANN specs for those interesed:

Input Nodes: 768
Hidden Nodes [Layer 1]: 1024
Hidden Nodes [Layer 2]: 512
Output Nodes: 1

Total Nodes: 2305
Total Connections: 1,311,232

Total Backpropogations to Date: 284,552

Unfortunately, I am still yet to set up a web site for Octavius as my plan
has always been to make him available for free public download. Though you
might still find him using search engines on some older sites.

I am currently working on Version 2.0 with some nice visual additions for
analysis, as well as a "tutor" mode.

Have you considered some kind of network client so that he (it is a boy
right?) can play other people on the net? Or, maybe he could play on
FICS (is the protocol open?)??? Either way, this would get him lots
more real-world training than you can provide.

Luke,

Do you want some free web space? I have lots of space to spare for
neural network applications. Send me an e-mail if you are interested.
