Tóm tắt

Dựa trên những kết quả lý thuyết gần đây của Zhao và Li [Math. Oper. Res., 26 (2001), tr. 119—146], chúng tôi trình bày trong bài báo này một phương pháp theo đường mới cho các vấn đề kết hợp không tuyến tính P*. Khác với hầu hết các thuật toán điểm trong hiện tại dựa trên đường trung tâm, thuật toán này theo dõi 'đường trung tâm điều chỉnh' mà tồn tại cho bất kỳ vấn đề P* liên tục nào. Kết quả cho thấy rằng thuật toán này hội tụ toàn cục cho bất kỳ vấn đề P* nào với điều kiện tập nghiệm của nó không rỗng. Bằng cách lựa chọn khác nhau các tham số trong thuật toán, chuỗi lặp có thể tiếp cận đến các loại điểm khác nhau trong tập nghiệm. Hơn nữa, sự hội tụ siêu tuyến tính địa phương của thuật toán này cũng có thể đạt được dưới một số điều kiện nhất định.
