WebMar 3, 2016 · 1 Answer. I'm going to base this on networkx's implementation. Bidirectional Dijkstra stops when it encounters the same node in both directions - but the path it returns at that point might not be through that node. It's doing additional calculations to track the best candidate for the shortest path. WebJul 10, 2024 · The algorithm. The algorithm is pretty simple. Dijkstra created it in 20 minutes, now you can learn to code it in the same time. Mark all nodes unvisited and store them. Set the distance to zero for our initial node and to infinity for other nodes. Select the unvisited node with the smallest distance, it's current node now.
