Shortest Path Graph Algorithms: Terminology and Core Concepts

Graph algorithms form the backbone of modern routing, networking, and pathfinding systems, but mastering them requires a solid grasp of their specialized vocabulary. This text-based course helps you build a rock-solid foundation in shortest path terminology and the underlying mechanics of key graph algorithms. You will transition from a beginner to confidently discussing, analyzing, and selecting the right shortest path approach for various computational problems. What you'll learn: • Define core graph theory terms including vertices, edges, weights, directed, and undirected graphs. • Understand the fundamental mechanics of classic routing algorithms like Dijkstra's and Bellman-Ford. • Identify key differences between single-source shortest path and all-pairs shortest path problems. • Recognize the impact of negative edge weights and how to detect negative cycles. • Practice your knowledge through written conceptual scenarios and self-assessment terminology exercises. The course starts with essential definitions and structural concepts of graphs, gradually moving into the logical flow of major pathfinding algorithms, and concludes with written review exercises to reinforce your understanding. This program is designed for beginner programmers, computer science students, or self-taught developers with no prior graph theory experience.
