The challenge I've come up against is: the distances are all that is passed in. That is fine for just finding the closest pairs, but when you want to join one cluster with a point or another cluster, I don't see an easy way to determine the location of a cluster. What I've found so far is that I have to determine a new coordinate space for the elements and place each element into that coord space. I can't think of a simple algorithm to place objects into a coordinate space using their distances. Also, since the distances were determined in a generalized way, I'm not sure that what I've said above is even correct.
Any pointers? Bill
