Hello Thiago,

I have found nothing about AI, closest to your goals are neural networks.
There is a Squeak binding to the FANN library (fast artificial neural network) on Sourceforge.
Luciano Notarfrancesco has done some work (Google for NeuralNetworks.cs.gz and the name). This imho was done for self study so may be the closest to your needs.
I have implemented a kind of self organizing feature map which I use in a commercial app for quality testing. I'm free to distribute this but it's not aimed at studying.
I'm interested in what you'll decide, so if you don't mind, keep me posted.
Cheers,
