Dear all,

I just found out that there's a difference in the number clusters retrieved when using FindClusters and ClusteringComponents for the same data set, even when completely the same settings are used:

Do[
koppels = RandomReal[{0, 100}, 500];
cl = FindClusters[koppels, DistanceFunction -> EuclideanDistance, Method -> "Optimize"];
indices2 = ClusteringComponents[koppels, Automatic, 1,  DistanceFunction -> EuclideanDistance, Method -> "Optimize"];
Print[{First@Dimensions[cl], Max[indices2]}];, 
{i, 1, 6}]

{2,2}

{2,2}

{1,2}

{2,2}

{1,2}

{1,2}

This shouldn't be the case, because the same clusters should be found either way.

Does someone have an idea of what's going on here?

Thanks for the information!

Jan
