WebKruskal’s Algorithm is a famous greedy algorithm. It is used for finding the Minimum Spanning Tree (MST) of a given graph. To apply Kruskal’s algorithm, the given graph must be weighted, connected and undirected. Kruskal’s Algorithm Implementation- The implementation of Kruskal’s Algorithm is explained in the following steps- Step-01: WebThis greedy algorithm first computes the value per unit weight of every item (i.e. v/w ). It then sorts v/w in descending order. After that comes the stage for filling the sack greedily-- by adding items in order of decreasing …
