Pathfinding (A* / Dijkstra)Live

grid search · draw walls

Controls

Drag on the grid to draw walls. A* uses a distance heuristic to head straight for the goal; Dijkstra explores blindly in all directions. Blue = start, pink = goal, green = shortest path.

HeuristicManhattan

Governing equation

f (n) = g (n) + h (n), h (n) = ∣Δ x ∣ + ∣Δ y ∣

Reading this result: A* adds the Manhattan-distance heuristic to Dijkstra, so it aims straight at the goal and expands far fewer cells while still returning a shortest path.
