Graph Traversal Algorithms

Graph traversal algorithms are methods for visiting all the nodes in a graph systematically, which can be performed using various approaches such as Depth-First Search (DFS) and Breadth-First Search (BFS). These algorithms are crucial for tasks such as searching, pathfinding, and analyzing graph structures.

Overview

Graph traversal algorithms are essential tools in computer science for exploring and analyzing graphs. They allow us to systematically visit all nodes and understand the relationships between them. The two primary algorithms, Depth-First Search (DFS) and Breadth-First Search (BFS), each have unique ...

Key Terms

Graph
A collection of nodes (vertices) connected by edges.

Example: A social network can be represented as a graph where users are vertices and friendships are edges.

Vertex
A fundamental unit of a graph, representing an entity.

Example: In a city map, each intersection can be a vertex.

Edge
A connection between two vertices in a graph.

Example: In a road map, a road connecting two intersections is an edge.

Directed Graph
A graph where edges have a direction, indicating a one-way relationship.

Example: Twitter follows can be represented as a directed graph.

Undirected Graph
A graph where edges have no direction, indicating a two-way relationship.

Example: Facebook friendships can be represented as an undirected graph.

Traversal
The process of visiting all the nodes in a graph.

Example: Using DFS to explore all nodes in a maze.
