Figure 7. We present Convergence curves of benchmark functions in Figure 7A-H. A: the convergence curves of $$f_1(x)$$; B: the convergence curves of $$f_2(x)$$; C: the convergence curves of $$f_3(x)$$; D: the convergence curves of $$f_4(x)$$; E: the convergence curves of $$f_5(x)$$; F: the convergence curves of $$f_6(x)$$; G: the convergence curves of $$f_7(x)$$; H: the convergence curves of $$f_8(x)$$.
