Markov chain and Markov process. The Markov property states that the future depends only on the present and not on the past. The Markov chain is a probabilistic model that solely depends on the

A Markov process, named after the Russian mathematician Andrey Markov, is a mathematical model for the random evolution of a memoryless system.Often the property of being 'memoryless' is expressed such that conditional on the present state of the system, its future and past are independent.. Mathematically, the Markov process is expressed as for any n and

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 MDP is and how it is used in RL. The environment of reinforcement learning generally describes in the form of the Markov decision process (MDP). Therefore, it would be a good idea for us to understand various Markov concepts; Markov chain, Markov process, and hidden Markov model (HMM). Markov process and Markov chain Both processes are important classes of stochastic processes. A Markov process is a random process for which the future (the next step) depends only on the present state; it has no memory of how the present state was reached. A typical example is a random walk (in two dimensions, the drunkards walk). The course is concerned with Markov chains in discrete time, including periodicity and recurrence.

A stochastic process is called Markovian (after the Russian mathematician Andrey Andreyevich Markov) if at any time t the conditional probability of an arbitrary future event given the entire past of the process—i.e., given X (s) for all s ≤ t —equals the conditional probability of that future event given only X (t). Markov models are a useful scientific and mathematical tools.

Markov processes are a special class of mathematical models which are often applicable to decision problems. In a Markov process, various states are defined. The probability of going to each of the states depends only on the present state and is independent of how we arrived at that state.

The approach is realized as a MATLAB tool where the user can use a steady-state based analysis called a Loss and But there are other types of Markov Models. For instance, Hidden Markov Models are similar to Markov chains, but they have a few hidden states[2].

A random process is a collection of random variables indexed by some set I, taking values in some set S. † I is the index set, usually time, e.g. Z+, R, R+.

Now for some formal deﬁnitions: Deﬁnition 1. A stochastic process is a sequence of events in which the outcome at any stage depends on some probability. Deﬁnition 2. A Markov process is a stochastic process with the following properties: (a.) The number of possible outcomes or states is ﬁnite.

Markov processes are widely used in engineering, science, and business modeling. They are used to model systems that have a limited memory of their past. For example, in the gambler’s ruin problem discussed earlier in this chapter, the amount of money the gambler will make after n + 1 games is determined by the amount of money he has made Markov process, sequence of possibly dependent random variables (x 1, x 2, x 3, …)—identified by increasing values of a parameter, commonly time—with the property that any prediction of the next value of the sequence (x n), knowing the preceding states (x 1, x 2, …, x n − 1), may be based on the last state (x n − 1) alone. The forgoing example is an example of a Markov process.
