IMPORTANT!!
FOR RUN THIS SCRIPT YOU MUST NEED TO CREATE A TABLE WITH:
CREATE TABLE `pagerank` (
`master` int(11) NOT NULL default '0',
`slave` int(11) NOT NULL default '0',
KEY `m` (`master`),
KEY `s` (`slave`)
);
Master is a page that apoints to slave...
If you wanna to modify your column or table name, you must change the mysql.php file.
The Guaranix Rank is an implementation of the PageRank (The Larry Page and Sergei Brin Algorithm).
Google the greater Web Search Engine uses the PageRank for search the better pages first.
This algorithm could be used to calculate witch page is more important that anothers.
On my test, on a Sempromp 1.8 GHZ 512 RAM, it took about one hour to calculate the
PageRank of 1.000.000 Web Pages ( Just 60000 are Crawled and the others are just links undowloaded jet)
From Wikipedia in English. Starting with an only page that is
http://en.wikipedia.org/wiki/Linus_Torvalds.
Here are the top of PageRank: *
