Figure 6.
The image contains three subplots. In part a, a three-dimensional scatter plot shows relationships between core loss in watts, volume in cubic centimetres, and L long in microhenry, with points forming a trade-off surface. In part b, a curve of hypervolume versus generation rises rapidly and stabilises near 0.05, indicating convergence. In part c, a matrix of pairwise scatter plots and distributions displays relationships among variables x zero to x five, including clustered patterns and correlations, with diagonal plots showing individual parameter distributions.(a) Pareto front obtained from the surrogate-based optimization; (b) convergence behavior of MOO process using the hypervolume performance indicator available in Pedregosa et al. (2011).The total optimization time requires approximately 7 min using a population size of 5,000 individuals over 100 generations. (c) scatter matrix of the input parameter combinations corresponding to the Pareto-optimal solutions shown in (a)
