Question

Need this ASAP. Thank you!

A network topology is shown as the following figure. Please compute its Dijkstra’s table by following Dijkstra’s algorithm and show the computing process step by step.

This image contains a directed graph and a table illustrating steps of an algorithm, likely Dijkstra's, to find the shortest path in a graph. **Graph Explanation:** - The graph consists of seven vertices labeled U, V, W, X, Y, Z. - Directed edges connect pairs of vertices with weights assigned to each edge: - U to V: 3 - U to W: 5 - V to W: 3 - V to X: 8 - W to X: 4 - W to Y: 7 - Y to Z: 2 - X to Z: 9 **Table Explanation:** - The table represents steps in calculating shortest paths. - Columns: - **Step:** Iteration of the algorithm. - **N':** The set of vertices whose shortest path from the source has been determined. - **D(V), D(W), D(X), D(Y), D(Z):** Represents the shortest known distance from the starting vertex at each step. p(V), p(W), p(X), p(Y), p(Z) are predecessors. - Row 0 shows initial distances from U to other nodes are set to infinity (∞) except for direct connections. D(W) has the shortest distance of 3, marked in a red circle, indicating it’s the next vertex considered for expansion. - The table implies ongoing calculations for the shortest path as additional rows would complete the algorithm's progress.
