The classical calculus of variations, optimal control theory, and dynamic programming in its discrete form are explained in the usual Chiang fashion, with patience and thoroughness. Dynamic optimization approach There are several approaches can be applied to solve the dynamic optimization problems, which are shown in Figure 2. Thus, it's an ideal problem for first learning dynamic optimization. Additionally, the work of Fu et al. Dynamic Optimization - KamienSchwartz.
