document: BackRank : an alternative for PageRank ? This paper proposes to extend a previous work , The Effect of the Back Button in a Random Walk : Application for PageRank ( 5 ) . We introduce an enhanced version of the PageRank algorithm using a realistic model for the Back button , thus improving the random surfer model . We show that in the special case where the history is bound to an unique page ( you can not use the Back button twice in a row ) , we can produce an algorithm that does not need much more resources than a standard PageRank . This algorithm , BackRank , can converge up to 30 % faster than a standard PageRank and suppress most of the drawbacks induced by the existence of pages without links .
