Minimum Spanning Trees (MST) Finding a Minimum Spanning Tree for the following graph based on eachof the following algorithm. You need to show the procedures step-by-step. You could directly draw thefinal MST but indicate the sequence of your search by writing a series of letters, i.e. (a), (b), (c)... underthe edges of the MST. This type of answer is preferred. Or else, you need to draw a graph for each stepseparately.Illustrate Kruskal's algorithm.Prim's algorithm (start with the node 'DFW').What are the running times for Kruskal's algorithm and Prim's algorithm?18462704146433780212352342ORD740867109012581121Fig. 1.

Q7 Using words or pseudocode, describe an algorithm that, for a unweighted, undirected graph G, determines whether or not the graph is connected. Use DFS(G,v) as a subroutine (that is you don't have to give the pseudocode of the DFS traversal, you can simply call it from your pseudocode.) Make sure that your description is not ambiguous.
Computer Science ASAP PLS In this assignment, you should input a single graph. Then run your DFS or BFS, MST, and Dijkstra's algorithm for the input graph. This input graph can be created by reading from a file or using keyboard to input.
1. Unreachable Nodes You have been given an undirected graph consisting of N nodes and Medges. The nodes in this graph are enumerated from 1 to N. The graph can consist of self-loops as well as multiple edges. This graph consists of a special node called the head node. You need to consider this and the entry point of this graph. You need to find the number of nodes that are unreachable from this head node. Create a function unreachableNodesCount (N, M, ListofEdges, HeadNode) where N is the number of nodes, M is the number of edges, List0fEdges contains list of edges in the graph and HeadNode is a special node which is the entry point of this graph. The function will return the number of nodes that are unreachable from the head node. Note: You will need to use N, M and List of Edges to first create the graph, as well as a search function to define the unreachable nodes count. >>>N = 10 >>> M = 10 >>> ListofEdges [(8, 1), (8, 3), (7, 4), (7, 5), (2, 6), (10, 7), (2, 8), (10, 9), (2, 10),…
b) B Di E: The Graph above shows how the execution of different tasks (represented by the vertices of the Graph) depend on the completion of other tasks. For example, prior to the starting of task D, tasks A and B need to be completed. You are required to find the linear ordering of the vertices such that if (u, v) is an edge, then u precedes v in the ordering. Show your working clearly.
5. (This question goes slightly beyond what was covered in the lectures, but you can solve it by combining algorithms that we have described.) A directed graph is said to be strongly connected if every vertex is reachable from every other vertex; i.e., for every pair of vertices u, v, there is a directed path from u to v and a directed path from v to u. A strong component of a graph is then a maximal subgraph that is strongly connected. That is all vertices in a strong component can reach each other, and any other vertex in the directed graph either cannot reach the strong component or cannot be reached from the component. (Note that we are considering directed graphs, so for a pair of vertices u and v there could be a path from u to v, but no path path from v back to u; in that case, u and v are not in the same strong component, even though they are connected by a path in one direction.) Given a vertex v in a directed graph D, design an algorithm for com- puting the strong connected…
The usage of linked lists in a certain fashion allows them to be used as a representation of adjacency lists on a graph. If you want to prove a point, you need to make it using an example. Is it true that no prior experience or education is needed to begin learning to code?
The Graph Data Structure is made up of nodes and edges. (A Tree Data Structure is a special kind of a Graph Data Structure). A Graph may be represented by an Adjacency Matrix or an Adjacency List. Through this exercise, you should be able to have a better grasp the Adjacency Matrix concept. You are expected to read about the Adjacency Matrix concept as well as the Adjacency List concept. Suppose the vertices A, B, C, D, E, F, G and H of a Graph are mapped to row and column indices(0,1,2,3,4,5,6,and 7) of a matrix (i.e. 2-dimensional array) as shown in the following table.

Python Graph Algorithms: Minimum Spanning Trees Note: There are helper functions (see 'required' below), and some of them (like Kruskal's Algorithm, WeightedQuickUnion, and such) can help answering this problem. Problem: Suppose you are an engineer working on designing a road network for a new town. The town has many residential areas and commercial centers that need to be connected efficiently. You decided to represent the town as a connected, undirected graph where each vertex represents a location, and each edge represents a road connecting two locations. The weight of each edge represents the distance between the two locations. To ensure the road network is efficient, you need to find the minimum spanning tree of the graph. However, due to budget constraints, you can only construct roads with a maximum distance limit. You need to determine for how many pairs of locations, the minimum spanning tree of the graph remains the same when the maximum distance limit of a road is increased…
Breath First Search Distance Given a directed graph as an adjacency list, you will determine, in this challenge, the breath first search distance of all nodes from a starting vertex, s, assuming that the weight of each edge is 1. In the example graph belove, for s=0, the distances of each vertex from s are 0 1 1 2 3 The output includes the distances for the vertices, 0, 1, 2, 3, 4, in the order of the vertex number. If s=1, then the output will be -1 0 -1 1 2 For the starting vertex 1, the vertex 0 and 2 are unreachable, so the corresponding BFS distances are -1 and -1. Input Format First line in the input contains the starting vertex s Each of the subsequent lines contains two space-separated integers, v and w, that represents an edge from the node v to w. Constraints Node numbers are 0 based, i.e. if there n nodes, the nodes are numnered as 0,1,2,...,n-1. Output Format Print the distace of each vertex from the start vertex in the order of the vertex number. Sample Input 0 0 0 1 0 2…
Graph Transversal Simulation: For this graph write down the order of vertices encountered in a breadth-first search starting from vertex A. Break ties by picking the vertices in alphabetical order (for example, A before Z)
In the figure below there is a weighted graph, dots represent vertices, links represent edges, and numbers represent edge weights. S 2 1 2 1 2 3 T 1 1 2 4 (a) Find the shortest path from vertex S to vertex T, i.e., the path of minimum weight between S and T. (b) Find the minimum subgraph (set of edges) that connects all vertices in the graph and has the smallest total weight (sum of edge weights). 2. 3.
Specifications: You will create an implementation of this algorithm. Your driver program should provide a graph and a source vertex in the graph. Your implementation should use Dijkstra's Algorithm to determine the shortest path using adjacency matrix representation. Specifically, given a graph and a source vertex in the graph, find the shortest paths from source to all vertices in the given graph, using Dijkstra's Algorithm.
