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?

Kruskal Algorithm
Complexity of Kruskal's algorithm for finding the minimum spanning tree of an undirected graph containing n vertices and m edges if the edges are unsorted is _______ ______________________________________________________________________________ If elements are sorted we do with Union Find algo with ... is $log^{*}V$ Now from here can we derive it for unsorted edges? for ref: here

#Graphs
Is there any best method for implementing kruskal algorithm without using priority queue?? and can we use min heap here??

How many MST is possible?
Given graph using Prim’s or Kruskal’s algorithm, find out that how many distinct minimum cost spanning trees are possible___? My answer was 1 and given is 2 ,what I am missing ? Edit:I had confirmed with it and answer is only one tree possible.

cormen
calculating time complexity of kruskal algorithm by this way is right? build min heap- storing edges - O(n) extracting edges V-1 times - O((v-1) log E) ~ O(V log E) so total time complexity is O(E +V log E) or O(E+ E log E) while extracting edges if first V-1 edges ... it is best case- O(E+ V log E) and if need to extract all edges because only last edge is not creating cycle - O(E+ E log V)

Difference between Kruskal's and Prim's algorithm ?
It may be the case that "Kruskal's Algorithm may not maintain connectivity while Prim's algorithm always does that" ? Any example which favours this ?

Analysis OF Kruskal's Algorithm
I have seen many varients of complexities using diferent data structures in implementing Kruskal Agorithm. Can you pls post standard algorithm and tells me in details how to derive the complexities. Please also mention the variations possibles when data structure changes and How will effect the complexity taking Best case and Worst case senarios .

How does Kruskal algorithm detect cycle in the graph and what is the time taken ?
Does it tale constant time or the time taken proportional to search in the entire partition of elements to find whether the component lies in that same component or not ?
