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

Figure 8

The convergence of the discrete evolution on the Schwefel function utilizing the different SFCs (red: Z-order, yellow: Hilbert, and green: C-curve). The vertical axis ( scale) shows the fitness value expressed by a multiple of the best solution precomputed analytically. The measurements were performed 20 times for two different vertex distributions ((a) Gaussian; (b) Gaussian islands) and the same parameters (Table 2).
