the FLPs 2 and 16 are the suitable FLPs in YK-model, the distance of these two FLPs are only 0.4975 and 0.4019, which are relatively low compared to other FLPs. When the distance is considered as a relatively important criterion, these two FLPs are eliminated. The FLPs 4 and 17 with relatively low adjacency score, 0.6 and 0.6, respectively, were rated high because of the advantage of relatively higher distances and accessibility.
