Jan 6, 2021 · 本文介绍了networkx库在图的连通性分析中的应用，包括如何判断图是否连通、获取连通分量数量及节点集合，以及如何生成和绘制连通分量子图。 示例代码展示了如何利用networkx分析一个具有多个连通分量的图，并提供了获取包含特定节点的连通分量的方法。 摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 > 连通性定义：若一个途中人两点间有路径相通，则称此图为连通图。 例如： networkx学习与使用——（3）路与圈 中创建的APANET就是一个连通图，但并不是所有的图都是连通图。 则称该子集为图G的一个连通分量。 具体实例如下： 上图的例子共有三个连通分量，这是很直观的。 事实上对于一个图，我们对连通性的需求通常有两点： 该图是否连通？ is_strongly_connected # is_strongly_connected(G) [source] # Test directed graph for strong connectivity. If G is directed. In networkX we can use the function is_connected(G) to check if a graph is connected: is_strongly_connected# is_strongly_connected (G) [source] # Decides whether the given tournament is strongly connected. We will use the networkx module for realizing a Complete graph. Jun 24, 2013 · You received this message because you are subscribed to the Google Groups "networkx-discuss" group. Parameters: GNetworkX Graph An undirected graph. NetworkX的安装和导入. An undirected graph. Returns True if the graph is semiconnected, False otherwise. Return the complete graph K_n with n nodes. A directed graph is strongly connected if and only if every vertex in the graph is reachable from every other vertex. In Python, good old Numpy has our back, and provides a function to compute the eigenvalues of a square matrix. is_connected# is_connected (G) [source] # Returns True if the graph is connected, False otherwise.
