I have recently purchased this book and it hasn’t left my side for several days. I highly recommend it.

yes, i second it too! ;D i loaned it from my university library for some research and its a really good book. you can visit the author’s website at http://www.ai-junkie.com he has some articles on his site as well.
I’ve also found that site and loved it! The Smart Sweepers example was really informative for me. As a little way to give thanks I converted it into Java since he didn’t already have one. It’s not available on the site yet, but here it is if you want to use it 
just wanna ask, anyone know of code examples in java? i have no experience in c so java code samples would save me time. a lot of time
I converted, and improved some , the code to BlitzMax basic. It probably won’t help but if you want it it is in this zip

and there are dicussions about it at

and
frulica, if you read the post JUST above yours you’ll see my link to Java source code for this very example
