Question
**Title: Implementing and Analyzing Dijkstra’s Algorithm** **Objective:** Implement Dijkstra’s algorithm (referred to as Algorithm 4.3) on your system, and examine its performance using various graphs. **Detailed Steps:** 1. **Algorithm Implementation**: - Understand the fundamentals of Dijkstra's algorithm, which is used to find the shortest path from a single source node to all other nodes in a graph. - Implement the algorithm in your preferred programming language following the description provided in Algorithm 4.3. 2. **Performance Analysis:** - Test the implemented algorithm on different types of graphs. These may include: - Dense Graphs: A graph with a high number of edges compared to the number of nodes. - Sparse Graphs: A graph with relatively few edges. - Directed Graphs: Graphs in which edges have a direction. - Undirected Graphs: Graphs in which edges do not have any direction. - Weighted Graphs: Graphs where edges have assigned weights or costs. - Unweighted Graphs: Graphs where all edges are considered to have the same cost, usually represented as 1. 3. **Evaluation Metrics:** - Measure the algorithm's performance in terms of time complexity for the various types of graphs. - Analyze the efficiency and any potential bottlenecks that arise during the processing of these graphs. 4. **Graphical Representation:** - Create visual aids such as graphs, charts, or tables to represent performance metrics, like execution time against the number of nodes or edges. - Use these visual tools to compare performance across different graph types and sizes. **Conclusion:** By implementing Dijkstra’s algorithm and analyzing its performance across different graph structures, you will gain a deeper understanding of its practical applications and efficiency in various scenarios.
