All about Graph pathfinding algorithms. How they work, the data structures they use, their time and space complexity, and practical use cases. Use this article as a learning resource and a technical reference guide.
Graph traversal systematically visits vertices. Depth‑First Search dives deeply along paths; Breadth‑First Search expands layer by layer. Built‑ons like topological sort and component detection exploit these passes to order DAGs and expose connectivity.
Dive into graph traversal: BFS for shortest unweighted paths, DFS for exhaustive discovery, plus weighted variants—Dijkstra, A*, bidirectional, and heuristic search. Understand frontier control and edge‑cost strategy for optimal exploration.
