WebActor-critic (AC) agents implement actor-critic algorithms such as A2C and A3C, which are model-free, online, on-policy reinforcement learning methods. The actor-critic agent optimizes the policy (actor) directly and uses a critic to estimate the return or future rewards. The action space can be either discrete or continuous.
