Discounted cumulative reward

In the previous section, we said this: the goal of reinforcement learning is to learn a policy that, for each state s in which the system is located, indicates to the agent an action to maximize the total reinforcement received during the entire action sequence. But how can we maximize the total reinforcement received during the entire sequence of actions?

The total reinforcement derived from the policy is calculated as follows:

Here, r_T represents the reward of the action that drives the environment in the terminal state s_T.

A possible solution to the problem is to associate the action that provides the highest ...
