Question
**Title: Finding the Shortest Path in a Weighted Graph** --- **Problem Statement:** Find the length of a shortest path between vertices \(a\) and \(z\) in the given weighted graph. **Graph Description:** The graph consists of seven vertices labeled \(a, b, c, d, e, f, g,\) and \(z\). The edges between these vertices are assigned weights as follows: - \(a\) to \(b\): 4 - \(a\) to \(c\): 3 - \(b\) to \(c\): 2 - \(b\) to \(d\): 5 - \(c\) to \(e\): 6 - \(d\) to \(e\): 3 - \(d\) to \(f\): 5 - \(e\) to \(g\): 5 - \(f\) to \(z\): 7 - \(g\) to \(z\): 4 **Graph Structure:** - The graph is laid out in a horizontal manner. - Vertices \(a, b, c\) form the leftmost section. - Vertex \(d\) is central connecting to \(b, e,\) and \(f\). - Vertices \(e\) and \(g\) are connected with \(d\) forming pathways towards \(z\). - Vertices \(f\) and \(g\) directly lead to the endpoint \(z\). **Objective:** Determine the path with the minimum total weight connecting \(a\) and \(z\). **Approach:** To solve this problem, you can utilize algorithms like Dijkstra’s or Bellman–Ford to calculate the shortest path in a weighted graph. **Conclusion:** Identify and sum the weights of the edges in the shortest path between the specified vertices. The graph visually supports exploring different paths and comparing their cumulative weights. **Note:** The box in the lower-left corner remains unspecified, as it does not pertain to the problem at hand.
