The Six Degrees of Kevin Bacon game, from which our project takes its name, is basically a game of finding shortest paths (with a path length of six or less) from Kevin Bacon to any other actor. Let’s find the shortest path between Margaret Fell and George Whitehead: fell_whitehead_...

一个关系网可以通过很多方式取衡量,在前一章,2个节点的距离由他们的最短路径决定。 NetworkX提供了集中衡量距离与最短路径的方法。2个节点间的最短距离可以通过all_shortest_paths()来发现 list(nx.all_shortest_paths(G_karate,mr_hi,john_a))[[0,8,33],[0,13,33],[0,19,33],[0,31,33]] ...
