------------------------------------------------------------------

Consider one of the earlier papers: 
[http://ilpubs.stanford.edu:8090/422/1/1999-66.pdf]

I have not read it in detail, but it looks like just changing the random jump 
probability distribution in current PageRank implementation should do the 
trick. The current PageRank implementation assumes a uniform distribution for 
it. Again, we will have to read the paper carefully to see if my statement 
above is indeed correct.

There is also a R implementation of PPR, for us to verify the correctness of 
our own implementation:

[https://stats.stackexchange.com/questions/176534/validating-personalized-pagerank-matrix-computation-in-r]]

The implementation of the library is in C I think 
([https://github.com/igraph/igraph/blob/536ac19e0a48bba89942ce190dc81484b520fb46/src/centrality.c).]
 They use the matrix computation approach to solve it.
