I think the previous reviewer got it wrong: It is very clear from the editorial introduction and from the table of contents that this book is about the ANALYSIS of parallel genetic algorithms, not about their implementation. The problem here is that implementing these algorithms is relatively easy, but configuring them is very complicated because there are many parameters. The work of Cantu-Paz---excellently summarized in this little book---is the best analysis available for the different types of parallel genetic algorithms.
I recommend this book wholeheartedly.
