WebKruskal's algorithm is an example of a "greedy" algorithm, which means that it makes the locally optimal choice at each step. Specifically, it adds the next smallest edge to the tree that doesn't create a cycle. This approach has been proven to work for finding the minimum spanning tree of a graph. Kruskal's algorithm uses a data structure called a disjoint-set … Web2 days ago · The set covering is a well-known NP-hard problem in the combinational optimization technique. We call the set cover problem as NP-Hard, because there is no polynomial real time solution available for this particular problem.
