Each household has the following utility function U = X1 t=0 tu(c t) L t H; (1) Incremental Dynamic Programming and Differential Dynamic Programming were also used in the reservoir optimization problem. This section further elaborates upon the dynamic programming approach to deterministic problems, where the state at the next stage is completely determined by the state and pol- icy decision at the current stage. 1 Introduction A representative household has a unit endowment of labor time every period, of which it can choose n t labor. In this study, we compare the reinforcement learning based strategy by using these dynamic programming-based control approaches.

Deterministic Dynamic Programming A general method for solving problems that can be decomposed into stages where each stage can be solved separately In each stage we have a set of states and set of possible alternatives (actions/decisions) to select from Solving the shortest path problem Each stage contains a set of nodes. 1) Optimization = A process of finding the "best" solution or design to a problem 2) Deterministic = Problems or systems that are … In fact, the fundamental control approach of reinforcement learning shares many control frameworks with the control approach by using deterministic dynamic programming or stochastic dynamic programming.

In most applications, dynamic programming obtains solutions by working backward from the end of a problem toward the beginning, thus breaking up a large, unwieldy problem into a series of smaller, more tractable problems.

In contrast to linear programming, there does not exist a standard mathematical for-mulation of “the” dynamic programming problem. dynamic programming, economists and mathematicians have formulated and solved a huge variety of sequential decision making problems both in deterministic and stochastic cases; either finite or infinite time horizon. It serves to design rule-based strategies based on optimal solutions, tune control parameters and produce training data to develop machine learning algorithms, among others [1, 40, 41].
