Solving The Shortest Path Problem

You use Dijkstra's algorithm every time you check GPS directions. Created in 1956, this method finds the most efficient route between two points by mapping out every possible connection in a network.

Edsger Dijkstra originally designed this algorithm to demonstrate the power of a new computer, completing the logic in his head during a coffee break. It remains the gold standard for calculating travel time in navigation apps worldwide. By systematically exploring the nearest paths first, it guarantees the shortest route is identified. This elegant process is essential for everything from mapping your morning commute to routing internet data across the globe.
