Find the steady state probability distribution for the web search engine model of exercise 9.7. A Web
Question:
We then create a random walk where the initial state is equally likely to be any one of the five pages. At each time instant, the state changes with equal probability to one of the pages for which a link exists. For example, if we are currently in state A, then at the next time instant we will transition to either state B or state C with equal probability. If we are currently in state B, we will transition to state C, D, or E with equal probability, and so on. Draw a transition diagram and find the probability transition matrix for this Markov chain.
It is this distribution that is used as the ranking for the each web page and ultimately determines which pages show up on the top of your list when your search results are displayed.
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
