问题描述
NetworkX所有最短路径算法和scipy floyd warshall算法之间有什么区别?有什么理由要优先于另一个吗?哪个最快?
What are the differences between the NetworkX all shortest paths algorithm and the scipy floyd warshall algorithm? Are there any reasons to prefer one over another? Which is fastest?
推荐答案
(对于那些不知道numpy floyd-warshall算法在networkx中可用的人)
(for those who aren't aware the numpy floyd-warshall algorithm is available in networkx)
networkx 对floyd_warshall_numpy的描述表示:
The networkx description of floyd_warshall_numpy states:
networkx single_source_shortest_path在稀疏图上效果更好.您应该意识到，如果使用各种"shortest_path"算法，这些算法将忽略边缘权重.各种Dijkstra算法都结合了边缘权重.
The networkx single_source_shortest_path works better on sparse graphs. You should be aware that if you use the various "shortest_path" algorithms, these ignore edge weights. The various Dijkstra algorithms incorporate edge weights.
