This book is also meant for those who wish to apply EC to a particular problem or within a given application area. To this group the book is valuable because it presents EC as something to be used, rather than just studied, and it contains an explicit treatment of guidelines for good experimentation. Finally, this book contains information on the state of the art in a wide range of subjects that are interesting to fellow researchers, as quick reference on subjects outside of their own specialist ?eld of EC.
