WebApr 5, 2024 · A minimum spanning tree (MST) or minimum weight spanning tree may be defined as a subset of the edges of a connected, edge-weighted undirected graph that joins all the vertices together, shorn of any cycles and with the minimum possible total edge weight. To be precise, it is a spanning tree whose sum of edge weights is as small as … 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.
