WebThe second convention emphasizes functional similarity in the sense that the directed analog of a spanning tree is a spanning arborescence. That is, take any spanning tree and choose one node as the root. Then every edge is assigned a direction such there is a directed path from the root to every other node. The result is a spanning arborescence. WebA minimum spanning tree is a subgraph of the graph (a tree) with the minimum sum of edge weights. If the graph is not connected a spanning forest is constructed. A spanning forest is a union of the spanning trees for each connected component of the graph. Parameters: G ( NetworkX Graph) –. weight ( string) – Edge data key to use for weight ...
