What is the most significant trade-off in selecting a pathfinding algorithm for an automated navigation system? The Three Algorithms I Tested I implemented three classic algorithms in Python using Pygame: 1. Dijkstra's Algorithm Explores uniformly in all directions Guarantees the absolute shortest path Very slow; explores thousands of nodes Best for: Offline planning 2. A * Uses a heuristic to guide search toward the goal Finds the shortest path, 80-90% faster than Dijkstra Requires a good heuristic for optimal performance Best for: Real-world navigation (Google Maps, Waze), video games, robotics 3.…
