Can you explain graph traversal?

Can you explain graph traversal?

Sure! Graph traversal is the process of visiting all the nodes in a graph. There are two main methods: Depth-First Search (DFS) and Breadth-First Search (BFS). Would you like to know more about how each method works?

Yes, please explain Depth-First Search.

Depth-First Search (DFS) explores as far down a branch as possible before backtracking. It uses a stack to remember the next node to visit. This method is great for searching deep into a graph.

What about Breadth-First Search?

Breadth-First Search (BFS) explores all neighbors at the present depth prior to moving on to nodes at the next depth level. It uses a queue to keep track of nodes to visit next. BFS is useful for finding the shortest path in unweighted graphs.

Can you give me an example of when to use each?

Certainly! Use DFS when you need to explore all possibilities, like in puzzles. Use BFS when you want the shortest path, like in social networks.
