Figure 9

Simulation results reporting the behavior of the individual pairwise support indices defined in this study. Panel (a) reports the PS matrix computed for the set of the five bioinformatics workflows presented in Figure 1 (a support value of 1.0 in the diagonal indicates that the corresponding element was always singleton in its class, whereas a support value of 1.0 in a non-diagonal position indicates that the two corresponding elements were always grouped together); panels (b) and (c) illustrate the distributions of the global individual PSG index obtained for the 120 workflows from the Armadillo dataset for the k-means and k-medoids partitioning algorithms, respectively.
