I bought this book a few years ago, by Koza. It has tons of working code in it-- each problem he steps through building up a solution with a working program:
This is one of my most prized computer books, perhaps the most prized book I have. Even though I wasn't a Lisper when I started reading this book, I ended up building (without realizing it at first) a little Lisp inside Python for exploring the concepts.
If you thought Koza's old website is inspiring, consider getting this book. It's huge and expensive, but to me it feels like one of the 3 books I'd want to bring with me to a desert island or through the destruction of civilization.
I tried copying and pasting the stuff in here: [http://www.genetic-programming.org/gplittlelisp.html] into a file and loading it into clisp but it throws a bunch of syntax errors.
anyone know where you can grab a working copy of it? (I have never used lisp before, so I am probably not the best person to debug by hand...)
