Number of solutions is not adequate!

Note
This analysis employs multidimensional scaling (Borg and Groenen, 2005) to compare the slip models. The dissimilarities are obtained for all pairs of slip models, viz. dissimilarity matrix and embedded in low dimensional Euclidean space. We define four categories or levels of similarity: ”excellent”, ”good”, ”fair”, and ”poor” with respect to a reference (or target) solution or a centroid measure in absence of a reference solution.

Graphical interpretation for the similarity scale is as follows:

Excellent	Solution/s located inside the innermost circle
Good	Solution/s located between the innermost and middle circle
Fair	Solution/s located between the middle and outermost circle
Poor	Solutions/s located outside the outermost circle
