Compare the breadth-first and depth-first search algorithms : Using Breadth-First Search (BFS)

This video tutorial introduces the breadth first search (BFS) algorithm, explaining its theory and application. BFS starts at a source vertex and explores all adjacent vertices before moving further. The algorithm uses a queue data structure to manage vertices, ensuring a first-in, first-out order. The video provides a detailed walkthrough of BFS using a sample graph, demonstrating how vertices are added to and removed from the queue. It also discusses stopping conditions, such as reaching a goal vertex, and concludes with a summary of BFS's optimal pathfinding capabilities.
