Nuevo1 Dead Ends in PageRank Computations (25 points) 
We learned about PageRank in lecture which is an algorithm for ranking webpages. In this 
problem, we are going to focus on dead ends and examine how they affect the PageRank 
computations. 
Suppose we denote the matrix of the Internet as the n-by-n matrix M, where n is the number 
of webpages. Suppose there are k links out of the node (webpage) j, and 
if there is a link from j to i 
ij = 
0 
otherwise 
For a webpage j that is a dead e...
