Shortest path vs. Sum-of-Pairs. The graph shows the MCC score over 120 (5!) permutations order of the five sequences of the glmS dataset that was used in Table 1. The MCC score is ranked from worst (left) to best (right). The lower (blue) line shows the value achieved by each one of the 120 permutations. The green line shows the increase in accuracy when the best of five different orders was reported. The upper (red) line shows the results where the path was ranked by using the Sum-of-Pairs approach i.e. summing the comparisons between all the pairs that comprise the path. These results clearly show that using the Sum-of-Pairs measure yields better predictions.
