I required this book for a class i was taking. Overall this is one of the worst text books i have ever used. The book is filled with somewhat technical and complex information regarding MPC, yet fails to provide topical examples illustrating the principles and theories behind the information. The only reason to ever buy a book this overpriced and disobliging is for a class.
