@codemadeeasy: Every time you hit "Go" in a maps app, it's quietly solving a graph problem. Intersections become dots, roads become lines, and the app hunts for the cheapest path. The core ideas go back to Dijkstra's algorithm (1959) and A* (1968), and they're still everywhere today. Free ways to play with it yourself: - Red Blob Games, Intro to A*: redblobgames.com/pathfinding - VisuAlgo, watch Dijkstra step by step: visualgo.net/en/sssp - Harvard CS50 AI, Lecture 0 (Search): cs50.harvard.edu/ai - OpenStreetMap, free real map data: openstreetmap.org Where would you use a shortest path?
