Is it also possible to see the result?
Attached, Calum
I don't believe this is the required result, is it?
The problem with this data is that it contains a lot of duplicates. If I cluster the cities into 5103 clusters, I get 47ms. On the other hand if I don't cluster them, then I get 4.1s. The expensive part is building the index of indexing on distances. The results are rather odd - the 500 locations I get have 991 neighbours. Regards, Calum
