  1. Comparative analysis of obtained clustering solutions in experiment 2 (not limited to the solutions in the efficiency frontier). The first column lists the number of clusters in the solutions. The second and third column give, respectively, the percentages of the sIB solutions that obtain a better MI-based Homogeneity and MI-based Separation scores with respect to the solutions of the other clustering algorithms (Click, K-means and SOM). The fourth column lists the percentages of the sIB solutions that obtain a better MI-based Homogeneity and Separation (combined) scores with respect to the solutions of the other clustering algorithms. The last column lists the existence of a sIB dominate solution over all the other solutions.
