whether to remove sinks by linking them with every node
The page rank of a node measures the probability of a web surfer visiting that node. At any node, the surfer is assumed to follow all outlinks with equal probability; in addition, the surfer may visit any node randomly with a certain probability (TeleportProbability).
The page rank algorithm uses an iterative procedure to find the page ranks. When the average change in the page ranks is less than the setting for Tolerance, the iterative process terminates.
