Webb6 nov. 2024 · The ways to represent weighted graphs are extensions of the unweighted graph’s representations. The weight matrix is a real matrix whose element represents the weight of the edge between the -th and -th nodes: The weights of actual edges are usually positive, so zero denotes that no edge exists between two nodes. WebbA minimum spanning tree ( MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. [1] That is, it is a spanning tree whose sum of edge weights is as small as possible. [2]
