What is the significance of the target vertex in the Dijkstra Algorithm?

The target vertex in the Dijkstra Algorithm is of significant importance as it serves as the destination or goal vertex for finding the shortest path from the source vertex. The algorithm aims to determine the shortest path from the source vertex to all other vertices in the graph, and the target vertex helps in identifying the specific destination for which the shortest path is being calculated.

By specifying the target vertex, the Dijkstra Algorithm focuses on finding the shortest path from the source vertex to that particular destination. It allows the algorithm to prioritize the computation and optimization of paths leading to the target vertex, rather than calculating the shortest paths to all vertices in the graph.

The significance of the target vertex lies in its ability to guide the algorithm towards finding the most efficient path to a specific destination. This is particularly useful in scenarios where there is a need to determine the shortest path between two specific vertices, such as finding the quickest route between two cities on a map or optimizing network routing.

Additionally, the target vertex helps in terminating the algorithm once the shortest path to the destination vertex has been found. This termination condition saves computational resources and improves the efficiency of the algorithm, as it does not need to continue exploring paths to other vertices once the target vertex has been reached.

In summary, the significance of the target vertex in the Dijkstra Algorithm is that it defines the specific destination for which the shortest path is being calculated. It guides the algorithm towards finding the most efficient path to the target vertex and allows for termination of the algorithm once the shortest path to the destination has been determined.
