## BOOK ´ Computational Complexity Æ Christos Papadimitriou

Computational ComplexityEnted in a rather simple way while manyare developed in the form of extensive notes problems and hints The book is surprisingly self contained in that it develops all necessary mathematical prereuisites from such diverse fields as computability logic number theory combinatorics and probability I received the book on time The book is very expensive However the pages of the book are too old It should be reprinted

Uctions and NP completeness cryptography and protocols randomized algorithms and approximability of optimization problems circuit complexity the structural aspects of the PNP uestion parallel computation the polynomial hierarchy and many others Several sophisticated and recent results are pres Yesit is generally hard for undergradute students even grad students If you are taking course Theory of computing I would like to recommend Sipser's or Cohen's books for introduction's supplement However this book covers too many topics therefore becomes too dense so that you should read it carefully I admit that I could not go through than 20 pages of this book in the beginning But I was keeping on reading and surveying some easy books Finally I understand most parts of this book However if some readers want some advanced and recent topics They should refer to some conference's papers hosted by ACM or IEEE
