Each paper is a theoretical study of some 4. Dynamic Optimization is a carefully presented textbook which starts with discrete-time deterministic dynamic optimization problems, providing readers with the tools for sequential decision-making, before proceeding to the more complicated stochastic models.The authors present complete and simple proofs and illustrate the main results with numerous examples and exercises (without solutions). Another name for such a procedure is Simulation-Optimization .
