CMSC 451: Minimum Spanning Trees & Clustering

WebA Minimum Spanning Tree (MST) is a subset of edges of a connected weighted undirected graph that connects all the vertices together with the minimum possible total edge weight. To derive an MST, Prim’s algorithm or Kruskal’s algorithm can be used. Hence, we will discuss Prim’s algorithm in this chapter. As we have discussed, one graph may ... WebKruskal's algorithm follows greedy approach as in each iteration it finds an edge which has least weight and add it to the growing spanning tree. Algorithm Steps: Sort the graph edges with respect to their weights. … WebThe algorithm relies on techniques from Borůvka's algorithm along with an algorithm for verifying a minimum spanning tree in linear time.

WebMar 27, 2024 · Prim's Algorithm was designed to find a Minimum Spanning Tree (MST) for a connected, weighted undirected graph. This means that the algorithm finds a "tree" (a structure that has no cycles) that connects all of the vertices via a subset of all available edges that have the smallest weight. Alike Dijkstra's algorithm, Prim's is a greedy ...
