Dear BrowserUK,
A 'cluster' is a rectangular subset of @sim?
Sorry, I'm not sure if I understand what do you mean by rectangular subset.
A cluster C is simply a subset of X and it can have uneven size.
The density of the cluster is the average of the values in the cluster?
Yes, I we use "average" as measure of density.
Which would make the problem: Find __some__ subset with the largest average value; and if two subsets have the same average, favour the largest subset?
Almost. Say C1 has average 0.8 but only 1 member (excluding centroid) , and C2 has average 0.7 with 5 members, we would weight C2 as better than C1.
