How does page rank algorithm work?
PageRank algorithmGoogle Algorithm is a link analysis algorithm, named after Larry Page and used by the Google search engine, that assign a numerical weighting to each element of a hyperlinked set of documents. In short PageRank is a vote by all the other pages on the web and about how important page is. A link to a page is counts as a vote of support.Equation of PageRank is......PR(A)=(1-d)+d(PR(T1)/C(T1)+…..+PR(Tn)/C(Tn))PR(Tn)= each page has a notion of its own self value. PR(T1) for the first page in the web all the way up to PR(Tn) for the last page.C(Tn) = each page spreads its vote out evenly among all of its outgoing links. The count or number of outgoing link for page 1 is C(T1), C(Tn) for page n and so on for all pages.PR(Tn)/C(Tn)=I four page (page A) has a back link from page "n" the share of the vote page A will get is PR(Tn)/C(Tn).d= all these fractions of votes is damped down by multiplying it by 0.85(the factor "d").(1-d)= the (1-d) bit at the beginning is a bit of probability math magic so the sum of all web pages or PageRank will be one.The PageRank of a page depend upon the PageRank of a page pointing to it.Once the PageRank calculations have settles down, the normalized probability distribution (the average PageRank for all pages) will be 1.0.PageRank of different sites:The PageRank of Google is 0.9/1The PageRank of facebook is 0.9/1The PageRank of reddit is 0.8/1
Why are page numbers useful?
As a reader it's easier to find the page where you left off. In an office presentation of a multi page document it makes it easier to refer to page so and so and those attending can jump quickly to the page.
All the page no of the pages of a book are added up to 1000 but there is a mistake committed during this addition One page is counted twice What is the page no of the page counted twice?
17
Near the end of page 124?
The start of page 125.
The sum of the page numbers on the facing pages of a book is 89 what are the page numbers on the right pages an the left pages?
The solution is: Let X = left page and X+1 = right page. X + (X+1) = 89. Solve for X; X = 44 which is left page and right page is X+1 = 45.
