Questions & Step-by-Step Solutions

In a weighted graph, if all edge weights are equal, which algorithm can be used to find the shortest path?
  • Step 1: Understand that a weighted graph is a graph where each edge has a weight (or cost) associated with it.
  • Step 2: Recognize that if all edge weights are equal, it means the cost to travel from one node to another is the same for all edges.
  • Step 3: Know that Dijkstra's algorithm is a method used to find the shortest path in a graph with weighted edges.
  • Step 4: Realize that since all edge weights are equal, the shortest path can also be found using a simpler method called Breadth-First Search (BFS).
  • Step 5: Conclude that both Dijkstra's algorithm and BFS can be used to find the shortest path in a graph with equal edge weights.
