WebApr 8, 2024 · Dijkstra can also be implemented as a maze solving algorithm simply by converting the maze into a graph. This can be done by carving your maze into a grid and assigning each pixel a node and linking connected nodes with equal value edges. However, with large mazes this method can start to strain system memory. WebHow Dijkstra's Algorithm works.
