Because the DYHS method and the DYHS+ method need the information of the original function of (1), we selected a collection of test problems from the CUTEr library and listed them in Table 1.Thefirstcolumn"Prob." denotes the problem number, and the columns "Name" and "n" denote the name and the dimension of the problem, respectively.
For the DYHS+ and the DYHS, we let [N.sub.f] and [N.sub.g] be the number of function evaluations and the number of gradient evaluations, respectively, and set Innerk = [N.sub.f]/3 + [N.sub.g] by automatic differentiation (see [10, 20] for details).
These figures revealed that the MDYHS+ method and the MDYHS + 1 method performed better than the DYHS method and the DYHS+ method.
