1 00:00:01,100 --> 00:00:02,890 So we have reached the final lecture 2 00:00:02,890 --> 00:00:05,860 of this class which will also conclude 3 00:00:05,860 --> 00:00:08,810 our study of discrete time, finite state space 4 00:00:08,810 --> 00:00:10,640 Markov chains. 5 00:00:10,640 --> 00:00:13,490 We will first review the steady-state behavior 6 00:00:13,490 --> 00:00:15,720 of Markov chains. 7 00:00:15,720 --> 00:00:18,562 Then, we are going to talk about a classical application 8 00:00:18,562 --> 00:00:23,620 of Markov chains to analyze the design of a phone system. 9 00:00:23,620 --> 00:00:26,670 And finally, we will see how we can calculate 10 00:00:26,670 --> 00:00:30,930 some interesting quantities that have 11 00:00:30,930 --> 00:00:33,300 to do with the behavior of Markov chains 12 00:00:33,300 --> 00:00:37,790 over a finite time horizon as opposed to in the long run. 13 00:00:37,790 --> 00:00:39,770 So let us start.
