Dynamic optimization and reinforcement learning
Dynamic optimization problems are concerned with the properties of dynamic systems that evolve deterministically or in an environment of uncertainty, and that can be acted upon/guided by means of control in order to optimize a certain criterion (optimal control). The origins and applications are very diverse: engineering (rocket: trajectory control), mechanics (car: turning the steering wheel, accelerator pedal), management, economy or finance, automatic learning, video games, robotics, etc...
The objective of this course is to present the tools and different basic mathematical approaches of the theory of optimal control, in particular dynamic programming, and to illustrate them with concrete applications, especially in economics and finance. The first part will deal with the deterministic framework, and the second part will focus on the stochastic framework with an introduction to the theoretical and algorithmic aspects of reinforcement learning.
