This book constitutes a comprehensive rigorous, and at the same time, readable introduction to the theory of optimal control. It is centered around the maximum principle, but the basic notions of the calculus of variations and Bellman's principle of optimality are also briefly covered. In presenting the basic theory of optimal control, the authors use the so-called geometric approach throughout the book.
