The Bellman-Ford Algorithm: Shortest Paths and Graph Optimization

Understanding how to find the shortest route in a network is a fundamental challenge in computer science, especially when dealing with negative edge weights where other algorithms fail. This text-based course guides you from the absolute basics of graph theory to implementing, optimizing, and tracing the Bellman-Ford algorithm. What you will learn: 1. Understand foundational graph concepts, including directed edge representations and weights. 2. Trace the Bellman-Ford algorithm step-by-step to find single-source shortest paths. 3. Detect negative cycles in weighted digraphs to prevent infinite routing loops. 4. Optimize redundant relaxation steps to improve practical execution time. 5. Implement the algorithm using modern, clean code structures with clear type hints. 6. Compare performance trade-offs between Bellman-Ford and Dijkstra's algorithm. You will start with essential terminology and graph representations, progress to the core relaxation mechanism, and finish by analyzing optimization techniques. This course is designed for beginner programmers, computer science students, and self-taught developers looking to strengthen their algorithmic thinking.
