Russell Eveleigh is using a Raspberry Pi Pico to demonstrate Dijkstra's algorithm visually with LEDs arranged as a map of the Cotswolds in England.

Edsger Dijkstra, one of the moving forces behind the acceptance of computer programming as a scientific discipline, has died. But his legacy lives on in every computer.

Contraction hierarchies are a simple approach for fast routing in road networks. Our algorithm calculates exact shortest paths and handles road networks of whole continents. During a preprocessing ...
