SCI results on low homology instances. Results on all low homology instances containing 2 (upper left), 3 (upper right), 5 (middle left), 7 (middle right), 10 (lower left), and 15 (lower right) instances from the BRALIBASE benchmark set. The y-axis gives the SCI score. The legend from the upper left plot applies to the other plots as well. Mind that the different APSI-ranges in the six plots are a result of the BRALIBASE benchmark set: there are, for example, no k 15 instances in BRALIBASE below 38%.
