...mns. The rows represent spatial polygons, some of which overlap others (i.e., not all rows are independent of each other). Given a particular row, the first column contains a unique "RowID". The second column contains the "Variable" of interest. The remaining 100 columns ("Overlap1" ... "Overlap100") each contain a row ID that overlaps this row (but if this row overlaps fewer than 100 other rows then the remainder of the columns "OL1...OL100" contain NA). Here's the problem: I need to select the subset of 500 independent rows that maximizes the m...
