WebDec 9, 2016 · The transition model depends on the current state, the next state and the action of the agent. The transition model returns the probability of reaching the state \(s^{'}\) if the action \(a\) is done in state \(s\). But given \(s\) and \(a\) the model is conditionally independent of all previous states and actions (Markov Property).

optimal_policy_t+1(s) = argmax_a (∑_s' T(s,a,s')V_t(s')) where a is all of the possible actions and V_t is the value. Updating the value looks something like: V_t+1(s) = R(s) + gamma * max_a(∑_s' T(s,policy_t(s),s')V_t(s') since the policy represents the best action at that time step.
