The book "Noncooperative Game Theory" explores how game theory can be used to solve engineering and computer science problems. By looking at who the players are, what their goals are, and how to find solutions, the book helps pinpoint the essence of design challenges. Unlike traditional optimization methods, game theory considers uncertainty in parameter selection to ensure acceptable performance in engineering applications. The book covers topics like zero-sum, non-zero-sum, and dynamic games, and includes a MATLAB guide for coding. Overall, the book offers students a new approach to tackling engineering and computer science problems.
