DiGraphMatcher.subgraph_is_isomorphic#
- DiGraphMatcher.subgraph_is_isomorphic()[source]#
如果
G1
的子图与G2
同构,则返回True
。示例
创建
DiGraphMatcher
时,参数的顺序很重要>>> G = nx.DiGraph([("A", "B"), ("B", "A"), ("B", "C"), ("C", "B")]) >>> H = nx.DiGraph(nx.path_graph(5))
检查 G 的子图是否与 H 同构
>>> isomatcher = nx.isomorphism.DiGraphMatcher(G, H) >>> isomatcher.subgraph_is_isomorphic() False
检查 H 的子图是否与 G 同构
>>> isomatcher = nx.isomorphism.DiGraphMatcher(H, G) >>> isomatcher.subgraph_is_isomorphic() True
