Adjacency List of the Graph eryar@163.com 一、图的邻接表 邻接表(Adjacency List)是图的一种链式存储结构。在邻接表中,对图中每个顶点建立一个单链表,第i个单链表中的结点表示依附于顶点Vi的边,对有向图是以顶点Vi为尾的弧。如下图所示的图用邻接表表示如下: 根据上图来定义用邻接表表示图的数据结构。...

Adjacency List Structure The simplest adjacency list needs a node data structure to store a vertex and a graph data structure to organize the nodes. We stay close to the basic definition of a graph - a collection of vertices and edges{V, E}. For simplicity, we use an unlabeled graph as...

Using a naïve array implementation on a 32-bit computer, an adjacency list for an undirected graph requires about 8 e bytes of storage, where e is the number of edges. Noting that a simple graph can have at most [Math Processing Error] edges, allowing loops, we can let [Math ...
