22. Applications of BFS and DFS

22. Applications of BFS and DFS

The chapter explores the applications and properties of graph traversal techniques such as Breadth-First Search (BFS) and Depth-First Search (DFS). It discusses how these methods can identify connected components, determine cycles, and reveal important structural features in both undirected and directed graphs. Additionally, the chapter highlights the classification of edges and presents the concept of strongly connected components in directed graphs.

What we have learnt

  • BFS and DFS can be used to explore graph structures and find paths between vertices.
  • Connected components can be identified using a systematic exploration of unvisited vertices in a graph.
  • Different types of edges, such as tree edges, forward edges, and back edges, have distinct properties relevant to cycles and connectivity.

Key Concepts

-- Connected Components
Groups of vertices in a graph where each vertex is reachable from any other vertex in the same group.
-- Cycles in Graphs
Paths in a graph that start and end at the same vertex, indicating a loop within the structure.
-- Tree Edge
An edge that is part of the traversal tree formed by BFS or DFS.
-- Strongly Connected Components
Subsets of a directed graph where every pair of vertices can reach each other.
