WebA policy is a function can be either deterministic or stochastic. It dictates what action to take given a particular state. The distribution π ( a ∣ s) is used for a stochastic policy and a mapping function π: S → A is used for a deterministic policy, where S is the set of possible states and A is the set of possible actions.
