Web26 nov. 2024 · A minimum spanning tree (MST) is a weighted, undirected, connected graph whose total edge weight has been minimized by removing heavier edges. In other words, we keep all the vertices of the graph intact, but we may remove some edges so that the sum of all edges is at a minimum.

WebNow for some more graph terminology. If some edge (u,v) is in graph G, then vertex v is adjacent to vertex u.In a directed graph, edge (u,v) is an out-edge of vertex u and an in-edge of vertex v.In an undirected graph edge (u,v) is incident on vertices u and v.. In Figure 1, vertex y is adjacent to vertex b (but b is not adjacent to y).The edge (b,y) is an out … WebThe Minimum Spanning Tree (MST) is an extensively studied problem and has various graph and geometric based applications. For a connected and undirected graph G(V,E) with positive edge weights, a minimum spanning tree (MST) is an acyclic subgraph of G which connects all the vertices in G such that the total edge weight is minimum.
