WebApr 7, 2024 · π: S × A ↦ [0,1] is a stochastic policy mapping state-action pairs (s t, a t) to the probability of choosing an action a t ∈ A when in state s t ∈ S at timestep t. P: S × A × S ↦ [0,1] is a state transition function mapping tuples (s t, a t, s t+1) to the probability of arriving in state s t+1 after taking action a t at state s t.
