Witryna2 lut 2016 · 5. One of the first things that I notice is that you define the Node as an instance variable. Better would be to define it at the top level: Node = namedtuple ('Node', ['coming_from', 'cost']) Also, in Dijkstra's algorithm, the key point is not the nodes, but the edges. An edge is a tuple (source, destination, weight). Witryna22 paź 2024 · In diesem Tutorial wird erläutert, wie Sie den Dijkstra-Algorithmus zum Finden des kürzesten Pfads in Python implementieren.
