What is MDP (markov decision process)?

Markov decision process (also called MDP): A mathematical model of sequential decision-making with a set of situations, a set of choices, transition probabilities, a score function and a discount factor. Its key assumption is that the next situation depends only on the current one and the choice made. Most learning methods assume it.
