图1:子图的简单例子。曲线是(可能是平凡的)路径;直线是实际的边。路径p xy。最后,pabpbc表示两条路径p ab和p bc的连接。目标.我们证明了迭代不增加新节点s,通过证明对于任何S,J(SUJ(S))= J(S),这证明了对于所有i,J1+ l(S)= Ji(S)。如果存在节点j EJ(S UJ(S)),其中j J(S),则j=

Finally, pabpbc means the concatenation of the two paths p ab and p bc. Goal. We prove that iterating adds no new node s by showing that J (SUJ (S))= J (S) for any S, which proves that J1+ l (S)= Ji (S), for all i. If there is a node j EJ (S UJ (S)) where j J (S), then j=
