March 29 2002 10:13:19.075 AM [This is a run in which we specify that we want 8 clusters, and we just try 30 different random initial configurations in search of the lowest energy solution. Note that after initialization and entry to HMEANS, there were many times when there was one or 2 or even 5 empty clusters. And the code I've written requires HMEANS to reinitialize the center of the empty cluster until it gets something in it. In a few cases, I had to do this about 100 times! And this only seemed to happen on entry to HMEANS, but never later in the algorithm.] CVT_BASIS Arrange PDE solution data into clusters.
