Question: Which traversal method is typically used to find the shortest path in an unweighted graph?

Options:

  1. Depth-First Search
  2. Breadth-First Search
  3. Dijkstra\'s Algorithm
  4. A* Search

Correct Answer: Breadth-First Search

Solution: 

BFS is used to find the shortest path in an unweighted graph because it explores all neighbors at the present depth prior to moving on to nodes at the next depth level.

Questions & Step-by-Step Solutions

Which traversal method is typically used to find the shortest path in an unweighted graph?
  • Step 1: Understand what an unweighted graph is. An unweighted graph is a graph where all edges have the same weight or no weight at all.
  • Step 2: Learn about traversal methods. Traversal methods are ways to visit all the nodes in a graph.
  • Step 3: Identify the two common traversal methods: Depth-First Search (DFS) and Breadth-First Search (BFS).
  • Step 4: Recognize that BFS explores all neighbors of a node before moving deeper into the graph. This means it looks at all nodes at the current level before going to the next level.
  • Step 5: Understand that because BFS explores level by level, it guarantees that the first time it reaches a node, it has found the shortest path to that node in an unweighted graph.
  • Step 6: Conclude that BFS is the preferred method for finding the shortest path in an unweighted graph.
