MH 8300 Tutorial Activity 10 PageRank Question 1. Consider the following webgraph with four websites. (a) Write down the adjacency matrix A for the webgraph. (b) Write down the Markov matrix M for the webgraph. (c) Based on your observations on the matrix M , the number of websites linking out of site i is the number of nonzero entries in row/column i , while the number of websites linking into site i corresponds to the number of nonzero entries in row/column i . (d) Determine the importance vector for the webgraph and rank the websites in descending order of importance.
Question 2. Consider the following webgraph (with ten websites) and its Markov matrix M . M = 0 1 2 1 2 1 3 1 2 1 2 1 3 1 7 0 0 1 2 0 1 2 1 3 1 2 1 2 1 3 0 1 3 0 1 2 0 0 0 0 0 0 1 7 0 0 0 1 2 0 0 0 0 0 1 7 0 0 0 0 0 0 0 0 0 1 7 0 0 0 0 0 0 0 0 0 1 7 0 0 0 0 0 1 3 0 0 0 1 7 1 3 0 0 0 0 0 0 0 1 3 0 0 0 0 0 0 0 0 0 0 1 7 0 1 0 0 0 0 0 0 0 0 1 3 0 (a) Consider the following eigenvalue and eigenvector pairs of M .

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
