Minimum Spanning Tree Tutorial: Prim- und Kruskal-Algorithmen

Both Prim’s and Kruskal’s Algorithms aim to find a minimum spanning tree in a connected, weighted graph, but they differ in their approaches.Recall that the minimum spanning tree must contain a total of n-1 n−1 edges, so we can use a variable cnt cnt that is incremented every time we add an edge to the minimum spanning tree. It finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized.The steps for implementing Prim’s algorithm are as follows: Initialize the minimum spanning tree with a vertex chosen at random.Kruskal’s Algorithm is a greedy algorithm that finds the minimum spanning tree (MST) in a connected, undirected graph.

Minimum Spanning Tree Tutorial: Prim’s and Kruskal’s Algorithms

In graph theory, there are two main algorithms for calculating the minimum spanning tree (MST): Kruskal’s algorithm. One method for computing the maximum weight spanning tree of a network G – due to Kruskal – can be summarized as follows. Prim ist konzeptionell sehr einfach.
