Neo4j version: 2.0.3
SingleSourceShortestPathBFS is set to CostType=Integer via it implementing
SingleSourceShortestPath<Integer>.
If I want to calculate the ClosenessCentrality if have to set it to
ClosenessCentrality<Integer> as well and its CostDivider<Integer> too. An
anonymous implementation would be (as in the test):
@Override
public Integer divideByCost(Double d, Integer c) {
// TODO Auto-generated method stub
return d.intValue() / c;
}
The resulting closeness is 0 though (should be 0.625 and 0.4166 in a small
test graph). Suggesting that because of the Integer conversion the results
get mangled.
So are SingleSourceShortestPathBFS and ClosenessCentrality just not
compatible?
BetweennessCentrality does work with SingleSourceShortestPathBFS.
