**Introduction to Complexity Theory**

by **Oded Goldreich** , **1999**

Complexity theory is the study of the intrinsic complexity of computational tasks. The book is aimed at exposing the students to the basic results and research directions in the field. The focus was on concepts, complex technical proofs were avoided.
