Web15 dec. 2013 · An overwhelming amount of practical applications (e.g., Page rank) relies on finding steady-state solutions. Indeed, the presence of such convergence to a steady state was the original motivation for A. Markov for creating his chains in an effort to extend the application of central limit theorem to dependent variables. http://www.statslab.cam.ac.uk/~yms/M7_2.pdf#:~:text=Convergence%20to%20equilibrium%20means%20that%2C%20as%20the%20time,7.1%20that%20the%20equilibrium%20distribution%20ofa%20chain%20can imts show in chicago 2022

Web11.1 Convergence to equilibrium. In this section we’re interested in what happens to a Markov chain (Xn) ( X n) in the long-run – that is, when n n tends to infinity. One thing that could happen over time is that the distribution P(Xn = i) P ( X n = i) of the Markov chain could gradually settle down towards some “equilibrium” distribution. Web2.2.
