Minimum cost spanning trees
WebA 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 … Web23 mei 2024 · 0. First find an MST using one of the existing efficient algorithms. Now adding an edge (v,w) creates a cycle in the MST. If the newly added edge has the maximum cost among the edges on the cycle then the MST remains as it is. If some other edge on the cycle has the maximum cost, then that's the edge to be removed to get a tree with lower …
