9299	10	10	10	10	40	very thorough parameter study
5839	7	10	10	10	37	optimal k is closer to 4 (similar to GM)

6631	10	10	10	10	40	chose more distinct colors for k-means clusters, hard to distinguish

1507	7	10	10	7	34	optimal k is closer to 4 (no elbow curve shown). dimension order for true data  (not eigenvectoirs) was requested

1489	7	10	10	5	32	nice clustering illustration for the 2D case, but should also try for higher D TSP not really used for any dimension ordering

9127	7	10	10	0	27	optimal k is closer to 4 (no elbow curve shown), no dimension ordering
4915	10	10	10	10	40	optimal k is closer to 4 -- repeat a few times and average the curve
