Reinforcement Learning and Control. The goal of reinforcement learning is for an agent to learn how to evolve in an environment. Definitions. Markov decision processes A Markov decision process (MDP) is a 5-tuple $(\mathcal{S},\mathcal{A},\{P_{sa}\},\gamma,R)$ where: $\mathcal{S}$ is the set of states $\mathcal{A}$ is the set of actionsthese games using reinforcement learning, surpassing human expert-level on multiple games [1],[2].

For most applications (e.g. simple games), the DQN algorithm is a safe bet to use. If your project has a finite state space that is not too large, the DP or tabular TD methods are more appropriate. As an example, the DQN Agent satisfies a very simple API: // create an environment object var env = {}; env.getNumStates = function() { return 8; }
