Utilization of the Discrete Differential Evolution for Optimization in Multidimensional Point Clouds

Figure 6

The ribbon plots comparing the evolutions on point-to-point (a) and point-to-line (b) distance minimization problems for different SFCs (red: Z-order, yellow: Hilbert, and green: C-curve) and artificial datasets with the Gaussian distribution (2-3 dimensions). The vertical axis ( scale) shows the fitness value expressed by a multiple of the best solution precomputed analytically. Each measurement was performed 20 times for the same parameters (see Table 1).
