用來表示有限集合中物件之間的關係,物件在圖中以「節點/頂點(node / vertex)」呈現、關係以「邊(edge / arc)」呈現。 一、圖/簡單圖/無向圖(simple graph / undirected graph) 節點之間的邊都沒有方向性,以「直線」呈現。 一張有 3 個節點、3 條邊的無向圖 二、有向圖(directed graph / digraph) 節點...
定义4(simple graph): A graph is simple if it has no loops, or multiple edges. A loop is an edge that only connects one node. A multiple edge is we've got two edges that are really the same. 也就是说两个nodes之间存在两个edge。 下图中node5的那个曲线应该是loop。 loop和multiple edg...
简单图(Simple Graph),指的是不包含任何自环的图(Self-loop),自环指的是联接与同一顶点之间的边,在某些场景中具有特定意义,但在简单图中不讨论。 通路(path)就是由m+1个顶点于m条边交替而成的一个序列,也就是说这些边依次首尾相连,其中沿途的边的总数m是通路的长度。注意通路中的边必须互异,但是顶点可能重...

Graph Theory - Types of Graphs - There are various types of graphs depending upon the number of vertices, number of edges, interconnectivity, and their overall structure. We will discuss only a certain few important types of graphs in this chapter.
