Of all of the books that delve into the details of cellular automata, the algorithms, and the kinds of problems you can solve with them, this is probably the best I've found. However, there are two major problems you will have to work around. First, there is the specialized and long defunct CAM computing environment. You simply have to not read the portions of the book that talk about it to get around this, and I found this a minor problem. A more major problem is that this old 1987 book is using Forth as a programming language for the algorithms. Outside of the boot proms on Sun computers and vintage early 80's home-brew computing magazines, I haven't seen this language used. However, C had not yet come to the forefront in 1987, so it's a forgivable, if annoying problem to have to learn enough about the language to truly "get" what the algorithms are doing. All in all, reading this book is like attending a fascinating and close sporting event with two guys - CAM and Forth - continually walking in front of you carrying a long pane of glass between them. The payoff is worthwhile, you just have to put up with something that the authors thought was a plus when they wrote the book that has now become an annoyance.
If you're brand new to cellular automata, I recommend "A New Kind of Science" by Wolfram. Although that book seems to have disappointed many of its readers, I think it does a good job of discussing cellular automata at a high level and discussing the kinds of problems that can be solved using it. Then come back to this book for details and algorithms.
