Graph is an important data structure and has many important applications. Moreover, grach traversal is key to many graph algorithms. There are two systematic ways to traverse a graph, breadth-first search (BFS) and depth-frist search (DFS). Before focusing on graph traversal, we first determin...

BFS intuition. Explore outward from s in all possible directions, adding nodes one "layer" at a time. (BFS的核心思想: 从s节点向外探索所有可能的方向,一次添加一个“层”节点。) BFS algorithm. L0 = { s }. L1 = all neighbors of L0. L2 = all nodes that do not belong to L0 or L1...
图算法中最基础的两个遍历算法:广度优先搜索(Breadth First Search,简称 BFS)和深度优先搜索(Depth First Search,简称 DFS)。BFS 从选定的节点出发,优先访问所有一度关系的节点之后再继续访问二度关系节点,以此类推。DFS 从选定的节点出发,选择任一邻居之后,尽可能的沿着边遍历下去,知道不能前进之后再回溯。 深度优...

对于无权图,通常使用基于BFS的算法;对于有权图,比较常见的有SPFA算法、Bellman-Ford算法等。 最短路径的用途十分广泛:在知识图谱中经常需要寻找两个实体之间的最短关联路径;基于黑名单和实体之间的关联可以发现其它顶点与黑名单之间的距离;而所有点对的最短路径可以帮助衡量各个顶点在整个图的拓扑结构所处的位置(中心...

图遍历（Graph Traversal）：从已识别的节点和边开始，通过图遍历算法（如BFS或DFS）扩展检索范围。图核...
五、樹遍歷(tree traversal) 「樹」是一種常見的資料結構,因此樹的遍歷常被詳加探討。 跟「圖」的遍歷一樣,樹遍歷的方式共可分「寬度優先搜尋(BFS)」與「深度優先搜尋(DFS)」兩大類。 寬度優先搜尋(breadth-first search, BFS) 由根開始,每層皆由最左至右,走到每層最右邊節點後,接下層最左邊節點。跟「...
