Explanation of Solution

Representing matrices for computing Page Rank

  • Google’s Page Rank algorithm uses a particular stochastic matrix known as Google matrix.
  • The google matrix represents a graph with edges representing links between pages.
  • The Page Rank of each page can be generated from the Google matrix iteratively using the power method.
  • The matrix should be stochastic, irreducible, aperiodic in order for the power method to converge...

Explanation of Solution

Finding PageRank

  • PageRank can be calculated by

 Page Rank for a given page= Initial Page Rank + (total ranking power / number of outbound links)

  • Google assigns every new web page as an initial Page Rank score...
