Clustering outcomes of MOEA/D initial populations by morphology.

Number of clusters Number of ring clusters Total ring solutions (%)
Gaussian 9 2 25.45
Disk 4 0 0
Ring 5 2 37.57

Notes. Overview of clustering results for initial points used in the MOEA/D algorithm. The table shows the total number of clusters identified with a similarity threshold of 10%, the number of the clusters that present a ring structure, and the percentage of the total solutions (out of 340) that exhibit ring-like morpohologies.
