WebIn mathematics, a Markov decision process (MDP) is a discrete-time stochastic control process. It provides a mathematical framework for modeling decision making in situations where outcomes are partly random and partly under the control of a decision maker.

Web20 de jun. de 2016 · Markov Decision Process (MDP) is a mathematical formulation of decision making. An agent is the decision maker. In the reinforcement learning framework, he is the learner or the decision maker. We need to give this agent information so that it is able to learn to decide. As such, an MDP is a tuple: $\left < S, A, P, \gamma, R \right>$.
