What is the runtime complexity of Kruskal's algorithm for finding the minimum spanning tree of a graph?
The runtime complexity of Kruskal's algorithm is O(E log V), where E is the number of edges and V is the number of vertices in the graph.
What is the runtime complexity of the Prim's algorithm for finding the minimum spanning tree of a graph?
The runtime complexity of Prim's algorithm is O(V2) or O(E log V), where V is the number of vertices and E is the number of edges in the graph.
What is the runtime of Prim's algorithm for finding the minimum spanning tree of a graph?
The runtime of Prim's algorithm for finding the minimum spanning tree of a graph is O(V2) with a simple implementation, or O(E log V) with a more efficient implementation using a priority queue.
Why will the shortest paths tree returned by Dijkstra's algorithm never be a correct minimum spanning tree (MST)?
The shortest paths tree returned by Dijkstra's algorithm will never be a correct minimum spanning tree (MST) because Dijkstra's algorithm prioritizes finding the shortest path from a single source node to all other nodes, while a minimum spanning tree aims to connect all nodes in a graph with the minimum total edge weight without forming cycles. Dijkstra's algorithm does not consider the overall connectivity of the graph, leading to potential inconsistencies with the requirements of a minimum spanning tree.
Can you provide the pseudocode for Kruskal's algorithm?
Here is the pseudocode for Kruskal's algorithm: Sort all the edges in non-decreasing order of their weights. Initialize an empty minimum spanning tree. Iterate through all the edges in sorted order: a. If adding the current edge does not create a cycle in the minimum spanning tree, add it to the tree. Repeat step 3 until all vertices are included in the minimum spanning tree. This algorithm helps find the minimum spanning tree of a connected, undirected graph.

Can dijkstra's algorithm produce a spanning tree?
yes, but a shortest path tree, not a minimum spanning tree
What is krushkal algorithm?
Kruskal's algorithm is an algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. This means it finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized. If the graph is not connected, then it finds a minimum spanning forest (a minimum spanning tree for each connected component). Kruskal's algorithm is an example of a greedy algorithm.
How can you find minimum spanning trees?
Minimum spanning trees can be found using algorithms like Prim's algorithm or Kruskal's algorithm. These algorithms work by starting with an empty spanning tree and iteratively adding edges with the smallest weights until all vertices are connected. The resulting tree will have the minimum total weight possible.

What is the significance of the cycle property in the context of Minimum Spanning Trees (MST)?
In the context of Minimum Spanning Trees (MST), the cycle property states that adding any edge to a spanning tree will create a cycle. This property is significant because it helps in understanding and proving the correctness of algorithms for finding MSTs, such as Kruskal's or Prim's algorithm. It ensures that adding any edge that forms a cycle in the tree will not result in a minimum spanning tree.
How do you use prim's algorithm to find a spanning tree of a connected graph with no weight on its edges?
Prims Algorithm is used when the given graph is dense , whereas Kruskals is used when the given is sparse,we consider this because of their time complexities even though both of them perform the same function of finding minimum spanning tree. ismailahmed syed
Who is the inventor of Reverse Delete Algorithm for MST When was this first published?
The Reverse Delete Algorithm for finding the Minimum Spanning Tree was first introduced by Edsger Dijkstra in 1959. He presented this algorithm in his paper titled "A note on two problems in connexion with graphs" which was published in Numerische Mathematik.
