The viewpoint is polyhedral, and Lee also uses matroids as a unifying idea. Topics include linear and integer programming, polytopes, matroids and matroid optimization, shortest paths, and network flows. Problems and exercises are included throughout as well as references for further study Combinatorial optimization,Tối ưu hóa tổ hợp Đình Thư, Trúc Trung tâm Học liệu Trường Đại học Cần Thơ
