本文簡要介紹
networkx.algorithms.chordal.chordal_graph_treewidth
的用法。用法:
chordal_graph_treewidth(G)
返回弦圖 G 的樹寬。
- G:圖形
NetworkX 圖
- treewidth:int
圖中最大集團的大小減一。
- NetworkXError
該算法不支持 DiGraph、MultiGraph 和 MultiDiGraph。該算法隻能應用於弦圖。如果發現輸入圖是非弦圖,則會引發
NetworkXError
。
參數:
返回:
拋出:
參考:
例子:
>>> e = [ ... (1, 2), ... (1, 3), ... (2, 3), ... (2, 4), ... (3, 4), ... (3, 5), ... (3, 6), ... (4, 5), ... (4, 6), ... (5, 6), ... (7, 8), ... ] >>> G = nx.Graph(e) >>> G.add_node(9) >>> nx.chordal_graph_treewidth(G) 3
