Let’s observe how we can implement this in Python … Note that a Markov chain is a discrete-time stochastic process. A Markov chain is called stationary, or time-homogeneous, if for all n and all s;s02S, P(X n = s0jX n 1 = s) = P(X n+1 = s0jX n = s): The above probability is called the transition probability from state s to state s0. X A game of tennis between two players can be modelled by a Markov chain X n A Markov chain is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. A countably infinite sequence, in which the chain moves state at discrete time steps, gives a discrete-time Markov chain (DTMC). A continuous-time process is called a continuous-time Markov chain (CTMC).

It is simpler to use the smaller jump chain to capture some of the fundamental qualities of the original Markov process. Toward this goal, Markov Decision Processes. The Markov Decision Process (MDP) provides a mathematical framework for solving the RL problem. Almost all RL problems can be modeled as an MDP. MDPs are widely used for solving various optimization problems. In this section, we will understand what an … De nition 2.1 (Markov process).

Markov Basics Constructing the Markov Process We may construct a Markov process as a stochastic process having the properties that each time it enters a state i: 1.The amount of time HT i the process spends in state i before making a transition into a di˙erent state is exponentially distributed with rate, say α i. Exist many types of processes are Markov process, with many di erent types of probability distributions for, e.g., S t+1 condi-tional on S t. \Markov processes" should thus be viewed as a wide class of stochastic processes, with one particular common characteris-tic, the Markov property.
