[chbot] Fwd: Sashin's genetic algorithm tennis player

Thu Jun 17 06:22:10 BST 2010

Charles,
           I used a neural networks, which was evolved by a genetic
algorithm.
The genetic algorithm sees the weights of the neural network as a GENE and
performs operations like cross breeding, mutation and evolves it.

Cheers
Sachin

NB: I will writeup a wiki on the google page, which should facilitate easy
compiling and running
the genetic framework.
