Mathematical methods in algorithm for websites positioning

Nowadays it is more and more common to treat the Internet as one of the ﬁrst sources of information. Given key words, diﬀerent types of web search engines generate a list of websites ranked by priority (theoretically corresponding to the query). The page position on the list depends on many factors. The method presented herein is a version of a PageRank algorithm introduced by Google to designate one of them. The PageRank algorithm ranks a webpage, depending on the number and quality of links leading to it and thus determines its position on the list. In its simplest version, the method can operate using just the basic operations on matrices. This paper presents also the more advanced version based on probabilistic approach.
