4.8 Random Walks & Pagerank

Random Walks

Consider the following random-walk graphs:

random walks
  1. Find \(d(x)\) for a stationary distribution for graph 1.
    Exercise 1

  2. Find \(d(y)\) for a stationary distribution for graph 1.
    Exercise 2

  3. Find \(d(z)\) for a stationary distribution for graph 2. Please answer in a fraction of the form x/y.
    Exercise 3

  4. If you start at node \(x\) in graph 1 and take a (long) random walk, does the distribution over nodes ever get close to the stationary distribution?
    Exercise 4
    No, you will just alternate between nodes \(x\) and \(y\).
