You could implement the LineRank algorithm, which was proposed as a scalable substitute for betweeness centrality: http://www.cs.cmu.edu/~ukang/papers/CentralitySDM2011.pdf --sebastian On 28.10.2013 17:09, Jyoti Yadav wrote: > Thanks Sebastian for your reply. > If we want to implement Betweennes

Thanks Sebastian for your reply. If we want to implement Betweenness Centrality algo then what should we do? Regards Jyoti On Mon, Oct 28, 2013 at 6:10 PM, Sebastian Schelter wrote: > Hi Jyoti, > > All-Pairs-Shortest-Path is a problem with a solution quadratic in the > number of vertices of th

Hi Jyoti, All-Pairs-Shortest-Path is a problem with a solution quadratic in the number of vertices of the input graph. For a reasonably large graph, you cannot even store the result. For most algorithms that map well to systems like Giraph the amount of messages per iteration is linear in the num

Hi.. one doubt is disturbing me..Would anyone suggest an idea? Is GIRAPH is designed for solving problems like AllPairShortestPath ? Thanks in advance. Jyoti
