Why does Kruskal's algorithm find the minimum spanning tree if it's greedy? Isn't a minimum spanning tree a global optimization problem? Isn't the point of being greedy is that there is a chance you won't find the most optimal solution? So how can Kruskal be able to find the minimum spanning tree while also being greedy?
Please can anyone tell me though Prim’s and Kruskal’s algorithms are greedy algorithms. Greedy algorithms always give local optimum solutions but how Prim’s and Kruskal’s algorithms are giving global optimum solutions why?
