FrontPage
The main objective of pr is to find a criterion that expresses the importance of the page. In the case of PageRank as such a criterion was chosen as the theoretical attendance page. To this end, consider the transition user on the links. Most often it begins to view sites with a randomly selected pages. Then on the download link it “clicks” to other resources. Moreover, there is a strong likelihood that the visitor will come out of the site and will resume the search from a random page (PageRank probability of 0.15 adopted at each stage).
Hence, with probability 0.85 he will continue the chosen path, “clicking” on one of them available on the open page of links (all Links for this have equal rights). So, traveling endlessly, he can go to popular pages many times, but on lesser-known – less. Accordingly, pr pages is calculated as the probability of finding a user on this page. The sum of the probabilities of all the pages in the network is equal to unity, since the user should be on any page. Due to the fact that use is probably not very comfortable.
