Neither can find all paths
Questions & Step-by-Step Solutions
Which traversal method is better for finding all paths between two nodes in a graph?
Step 1: Understand what a graph is. A graph consists of nodes (or vertices) connected by edges.
Step 2: Know the two common traversal methods: Depth-First Search (DFS) and Breadth-First Search (BFS).
Step 3: Recognize that DFS explores as far as possible along each branch before backtracking.
Step 4: Realize that when looking for all paths between two nodes, DFS will continue to explore until it finds all possible routes.
Step 5: Compare this with BFS, which explores all neighbors at the present depth before moving on to nodes at the next depth level, making it less efficient for finding all paths.
Step 6: Conclude that DFS is better for finding all paths because it thoroughly explores each path before moving on.
