Hi Stephane,This is achieved by the addition of the dampingVector in line 99. http://svn.apache.org/viewvc/mahout/trunk/core/src/main/java/org/apache/mahout/graph/linkanalysis/RandomWalk.java?view=markup --sebastian 2011/10/19 Stéphane Campinas<[email protected]>:Hi, I have a question regarding the code of the PageRankJob class [1]. I do not see where the "stochasticity adjustment" [2] is done in the code. It seems that a row of zeros is not replaced by 1/n*Ones(), with n the number of vertices and Ones() the vector with only 1 as values. Could you tell me where this operation is done ?
