Markov Decision Processes (MDPs) are a mathematical model for decision-making in uncertain environments. They consist of states, actions, transition probabilities, and rewards, forming the basis of reinforcement learning. MDPs are used in various fields, from healthcare to gaming, to develop strategies that maximize rewards over time. The Value Iteration algorithm and the Bellman equation are key to solving MDPs, while advanced topics like POMDPs address incomplete information scenarios.
