This book serves as an essential reference guide of established advances on PSO, as well as a stepping stone for further developments. It can be distinguished by relevant books by its specialization solely on PSO, without however restricting its algorithmic material to the narrow personal achievements and considerations of the authors. Thus, it can be valuable to a wide scientific audience of both novice and expert researchers.
