Definition
A Markov decision process is a 4-tuple, where
- is a finite set of states,
- is a finite set of actions (alternatively, is the finite set of actions available from state ),
- is the probability that action in state at time will lead to state at time ,
- is the immediate reward (or expected immediate reward) received after transition to state from state with transition probability .
(The theory of Markov decision processes does not actually require or to be finite, but the basic algorithms below assume that they are finite.)

Famous quotes containing the word definition:
“... we all know the wags definition of a philanthropist: a man whose charity increases directly as the square of the distance.”
—George Eliot [Mary Ann (or Marian)
“According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animalsjust as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.”
—Ana Castillo (b. 1953)
“Its a rare parent who can see his or her child clearly and objectively. At a school board meeting I attended . . . the only definition of a gifted child on which everyone in the audience could agree was mine.”
