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 $$ f_8(x) $$.
