层次化攻击路径图Graph(VERTEX,EDGE)是一个有向图的多重视图,包括脆弱性、主机层、安全域层攻击路径图。VERTEX是节点集,表示共记者在供给过程中经过的节点。EDGE是边集,表示节点之间的连接关系。在层次化的攻击路径图中,节点分为安全域,主机脆弱性等不同层次。有向边连接两个节点,表示攻击行为从一个安全域、主机...
In this study, we will show that vertex amalgamation graphs of a star graph with a path graph are edge-magic total and super edge-magic total labeling, with constructed vertex labelings and edge labelings to obtain intervals of the magic sums k.Suwandi, Selfa...
value attains the minimum among all graphs of a fixed order and a given vertex (edge) independence number or vertex (edge) cover number, and get some bounds for the vertex (edge) independence number, vertex (edge) cover number of a graph in terms of the least eigenvalue of the graph....
下面,我将实现vertex edge & graph 类.(c++) 同时我会使用 c++stl里的 list 关于list: 1.底层是双向链表。 2.支持的方法:这里就不赘述了。 #include <iostream> #include <unordered_map> #include <unordered_set> #include <list> 部分需要c++11才有的容器 ...
if there is no dangerous path, I can use a modified version of Dijkstra Algorithm, however, I do not know how to add the "dangerous" edge. I can delete all the "dangerous" edges and only remain one, this will find the path may or may not include the remaining "dangerous" edge, and...

Graph partitioning drives graph processing in distributed, disk-based and NUMA-aware systems. A commonly used partitioning goal is to balance the number of edges per partition in conjunction with minimizing the edge or vertex cut. While this type of partitioning is computationally expensive, we obser...
edge-regular graphcharacterization by parametersGiven a connected edge-regular graph Γ with parameters ( v, k , λ) and b 1 = k λ 1, we prove that in the case k ≥ 3 b 1 2 either |Γ 2 ( u )|( k 2 b 1 + 2) < kb 1 for every vertex u or Γ is a polygon, the ...
