Papadimitriou complexity theory

In his research, Papadimitriou used mathematical tools to uncover complexity, wherever it exists

He defined new classes of complexity, which have led to breakthroughs and new ways of understanding computational problems ( 8, 9 )

At roughly 40 years of age, Complexity theory is still an infant science

Thus we still do not have complete answers for any of these questions

(In a surprising twist, computational complexity has also been used to provide evidence for the hardness to solve some of the questions of

This text offers a comprehensive and accessible treatment of the theory of algorithms and complexity - the elegant body of concepts and methods developed by computer scientists over the past 30 years for studying the performance and limitations of computer algorithms
