Breadth first search in discrete mathematics

WebMar 24, 2024 · Path Finding. 1. Introduction. In this tutorial, we’ll show how to trace paths in three algorithms: Depth-First Search, Breadth-First Search, and Dijkstra’s Algorithm. More precisely, we’ll show several ways to get the shortest paths between the start and target nodes in a graph, and not just their lengths. 2. WebFeb 18, 2024 · Algorithm 16.4. 1: Depth-first search. To create a tree T that is a subgraph of a graph G wherein a path (in G) from v to v ′ is evident, begin with T containing the single vertex v and no edges. Set x = v. Look for a vertex y of G which is adjacent to …
