> Implementing RWR on Giraph should be a very simple modification of the
> SimplePageRankVertex code.
> {code}
> if ( myID == sourceID )
> DoubleWritable vertexValue = new DoubleWritable((0.15f + 0.85f * sum);
> else
> DoubleWritable vertexValue = new DoubleWritable(0.85f * sum);
> {code}
> It would be nice to make it as configurable as possible by using parametric
> damping factors, preference vectors, strongly preferential, etc...
> More or less along these lines:
