Expert Solution & Answer
Chapter 8, Problem 8PE
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...

- You are working with a database table that contains customer data. The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forwardWe are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.arrow_forwardConsider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks?
