LECTURE NOTES MARKOV DECISION PROCESSES LODEWIJK KALLENBERG UNIVERSITITY OF LEIDEN FALL 2009 Preface Branching appear from trading operations research roots of the 1950s, Markov finding processes (MDPs) behave gained recognition in such diverse ?elds as ecology, economics, and communion engineering. These applications have been tended to(p) by many theoretical advances. Markov finale processes, similarly referred to as stochastic dynamic programming or stochastic program line problems, argon simulations for sequential decision do when outcomes are uncertain. The Markov decision process model consists of decision epochs, states, accomplishments, observes, and regeneration probabilities. Choosing an action in a state generates a reward and determines the state at the next decision epoch with a transition probability function. Policies or strategies are prescriptions of which action to choose downstairs any eventuality at every(prenominal) future decision epoc h. Decision makers seek policies which are optimum in many sense. Chapter 1 introduces the Markov decision process model as a sequential decision model with actions, rewards, transitions and policies. We illustrate these concepts with some examples: an archive model, red-black gambling, optimal stopping, optimal control of queues, and the multi-armed despoiler problem.

Chapter 2 deals with the ?nite panorama model and the principle of dynamic programming, regressive induction. We also arena under which conditions optimal policies are monotone, i.e. nondecreasing or nonincreasing in the social club of the stat e space. In chapter 3 the discounted rewards! everywhere an in?nite horizion are studied. This results in the optimality equation and ancestor methods to solve this equation: policy loop-the-loop, linear programming, value iteration and modi?ed value iteration. Chapter 4 discusses the criterion of average rewards over an in?nite horizion, in the some general case. Firstly, polynomial algorithms are developed to classify MDPs as irreducible or communicating.
