Compared with the homotopy method (proposed by Yu and Lin, Appl. Math. Comput., 74(1996), 65), the main adavantages of this method are as foUows: on the one hand, it can solve the Brouwer fixed-point problems in a broader class of nonconvex subsets Ω in R^n (in this paper, we let Ω={x∈ R^n : gi(x) ≤0, i= 1,... , m}); on the other hand, it can also deal with the subsets Ω with larger amount of constraints more effectively.展开更多
