Comparing the results of different algorithms. (a) The scatter graphs of feasible and nondominated fronts from different algorithms. The colored z-axis represents the Ra FM. The abscissa and ordinate represent R/Q of the FM and HOM frequency respectively, and the number in brackets represents how many feasible and nondominated individuals exist in each algorithm. The red shapes represent the individuals picked up from these algorithms. (b) The scatter graphs of feasible and nondominated fronts from different algorithms, in which the colored z-axis represents the R/QHOM. (c) The geometric parameters of the SS cavity and the shape of an individual picked up from Fig. 4a.
