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...

关系匹配(Relational Matching):将查询中的关系与图数据源中的边进行匹配。 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(Graph Kernel):使用图核来衡量图之间的相似性,进行图级别的检索。 2. 基于学习的检索器(Learning-based Retriever) 浅层嵌入方法(Shallow...
This structure is ideal for graphs with fewer edges, and it allows for quick traversal of neighbors. Advantages Space-efficient for sparse graphs, requiringO(V + E)space. Efficient for graph traversal algorithms like Depth-First Search (DFS) and Breadth-First Search (BFS). ...
In mylast post, I have shown a way to unify the implementation of the most well-known graph-traversal algorithms. Now, let's make it more visually appealing and look into the performance differences. The story behind A few years ago, Yandex organized a contest calledRobots Courierswith an ...

DFS is a graph traversal algorithm that explores as far as possible along each branch before backtracking. It uses a stack (or recursion) to keep track of vertices to be explored. DFS can be used to −Traverse all vertices in a connected graph Detect cycles in a graph Find a path ...
