The performance of the strict clustering algorithm varies dramatically depending on the weighting schemes used to define subset similarity. The Y axis shows the difference in the AICc or BIC score compared to the best scheme found by the strict hierarchical clustering algorithm on the phylogenomic dataset from birds (Table 1). The X axes show the weights assigned to each of four parameter classes used to define subset similarity. Each panel shows 1000 data points, where each datapoint represents a single run of the strict hierarchical clustering algorithm under a particular weighting scheme. The set of four weights under which the best scheme was found by the strict hierarchical clustering algorithm are shown in red.
