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.

For decades, computer scientists working on negative-weight graphs tried to match the speed of Dijkstra’s algorithm with similar “combinatorial” algorithms. These involve discrete operations — like ...

To get a sense of Dijkstra’s algorithm, imagine yourself wandering through a graph, writing down the travel time from your starting point to each new vertex on a piece of scratch paper. Whenever you ...
