Compared with the degree distribution produced by
traditional scale-free network as is shown in Fig. 2, the
generation rule proposed in this paper has produced a degree
distribution in a relatively low value as is shown in Fig. 1;
there are some nodes of 0 degree as is shown in Fig. 1 on the
left for the random damage rule; as is shown on the right in
Fig. 1, there are no nodes with higher degree than the quantity
of 180 while there are some nodes whose degree are of higher
degree than the quantity of 180.
