For a project decision maker trying to evaluate the genetic algorithm approach, this book helps to understand the main concepts. It is a great for anyone who wants ideas to help evaluate the potentials and shortcomings of a GA system without getting mixed up in the math and details. It includes comparisons to chaos theory and neural nets.
For programmers looking implement code, or data administrators looking for the right data feeds, however, this book might be a frustrating tease. The book is full of examples such as mentioning the selection of "10 parameters from a possible 150 macroeconomic variables", but never says what the parameters are. The book is still useful. A little patience with this book might yield some great ideas although the author didn't directly communicate it. Never the less, just one small idea could easily pay for this book many many times over. For the pure IT developer, I highly recommend "Neural Networks in Finance and Investing" by Trippi & Turban instead which includes documented code and examples on a disk.
