Breadth-first search (BFS) is a fundamental algorithm used in computer science for traversing or searching tree or graph data structures. It's often compared to exploring a maze, where you systematically explore all possible paths to find the shortest one.
Starting Point: BFS begins at a designated starting point, typically called the "root" or "starting node."
Exploring Nearby: It explores all neighboring nodes of the starting point before moving on to deeper nodes.
Expanding Horizontally: BFS expands outwards horizontally, exploring all nodes at the current depth level before moving deeper.
Queue: To keep track of which nodes to explore next, BFS uses a data structure called a queue. Nodes are added to the queue as they are discovered and explored in the order they were added.
Marking Visited Nodes: To avoid revisiting nodes and getting stuck in infinite loops, BFS marks each node as visited after exploring it.
Finding the Goal: BFS continues this process until it either finds the goal (if searching for a specific node) or exhausts all possible paths.
BFS is a versatile algorithm with various applications in computer science and beyond.
