The book can serve as a text for a graduate complexity course that prepares graduate students interested in theory to do research in complexity and related areas.

Such a course can use parts of Part I to review basic material, and then move on to the advanced topics of Parts II and III. We study the P versus NP problem through properties of functions and monoids, continuing the work of [3]. Here we consider inverse monoids whose properties and relationships determine whether P is different from NP, or whether injective one-way functions (with respect to worst-case complexity) exist.

Particular attention will be given to the relationships between differrent computation models and to complete problems in the most relevant complexity classes. Computation complexity The per-bundle computation complexity at sender and receiver sides is mainly O RTTλ k with (n, k) (see Tournoux et al.

Meta-complexity refers to the computational complexity of problems whose instances themselves encode algorithms or computations. Some of the fundamental questions in theoretical computer science are questions about meta-complexity, including: Is the Satisfiability Problem solvable in less than exponential time.

The ﬁeld of Theoretical Computer Science (TCS), especially Computational Complexity Theory, is arguably the most foundational aspect of Computer Science.

One way to describe it is to say that a function is computable if its value can be obtained by an effective more rigor, a function: → is computable if and only if there is an effective procedure that, given any k-tuple of natural numbers, will produce the value ().
