Nothing
SOD (SelfOrganisingDeltoids) provides multidimensional scaling by gradually reducing the dimensionality of an initial space and using the resulting stress in the configuration to rearrange nodes. Stress is calculated from the errors in the internode distances, and the sum of the stresses at each node is combined to create Ndimensional force vectors that direct the movement of nodes as the dimensionality is iteratively reduced.
