Kruskal’s algorithm is a minimum spanning tree algorithm that takes a graph as input and finds the subset of the edges of that graph which. It falls under a class of algorithms called greedy algorithms which find the local optimum in the hopes of finding a global optimum. Any minimum spanning tree algorithm revolves around checking if adding an edge creates a loop or not. The most common way to find alggorithme out is an algorithm called Union FInd.

The Union-Find algorithm divides the vertices into clusters and allows us to check if two vertices belong to the same cluster algorthme not and hence decide whether adding an edge creates a cycle.

## Kruskal’s algorithm

We use standard template libraries to make our work easier and code cleaner. Prim’s algorithm is another popular minimum spanning tree algorithm that uses a different algoritbme to kruskap the MST of a graph.

Instead of starting from an edge, Prim’s algorithm starts from a vertex and keeps adding lowest-weight edges which aren’t in the tree, until all vertices have been covered. It takes a lot of effort and cost to maintain Programiz. We would be grateful if you support us by either:. Disabling AdBlock on Programiz.

Kruskal’s algorithm is a minimum spanning tree algorithm that takes a graph as input and finds the subset of the edges of that graph which form a tree that includes every vertex has the minimum sum of weights among all the trees that can be formed from the graph How Kruskal’s algorithm works It falls under a class of algorithms called greedy algorithms which find the local optimum in the hopes of finding a global optimum.

We start from the edges with the lowest weight and keep adding edges until we we reach our goal. The steps for implementing Kruskal’s algorithm are as follows: Sort all the edges from low weight to high Take the edge with the lowest weight and add it to the spanning tree. If adding the edge created a cycle, then reject this edge. Keep adding edges until we reach all vertices.
