4. Given a commected weighted directed graph with n vertices, what is the maximum mumber of possible tours in the Traveling Salesman Problem? 5. In the n-Queens problem as given in the textbook, where it is assumed that no two queens can occupy the same row on annx n chessboard, how many nodes are there in the total stat space tree without pruning? 6. As in the previous question, how many leaf nodes in the state space tree? z2 7....
Consider the problem of finding the shortest paths in a weighted directed graph using Dijkstra's algorithm. Denote the set of vertices as V, the number of vertices as |V|, the set of edges as E, and the number of edges as |E|. Answer the following questions.Below is a pseudo-code of the algorithm that computes the length c[v] of the shortest path from the start node s to each node v. Answer code to fill in the blank _______ .

Shortest paths Consider a directed graph with vertices fa, b, c, d, e, f and adjacency list representation belovw (with edge weights in parentheses): a: b(4), f(2) e: a(6), b(3), d(7) d: a(6), e(2) e: d(5) f: d(2), e(3) (i) Find three shortest paths from c to e. (ii) Which of these paths could have been found by Dijkstra's shortest path algorithm? (Give a convincing explanation by referring to the main steps of the algorithm.)
In Java: We say that a graph G is strongly-connected if, for every pair of vertices i and j in G, there is a path from i to j. Showhowtotest if G is strongly-connected in O(n + m) time. . Write a method and test it in Main. Explain why it is O(n+m). Graph is directed
Discrete Mathematics 6: A: Draw a graph with 5 vertices and the requisite number of edges to show that if four of the vertices have degree 2, it would be impossible for the 5 vertex to have degree 1. Repetition of edges is not permitted. (There may not be two different bridges connecting the same pair of vertices.) B: Draw a graph with 4 vertices and determine the largest number of edges the graph can have, assuming repetition of edges...
5. (10 pts) Give a concrete example of a directed and weighted graph G and two vertices u and v, where the Dijkstra's algorithm does not find the shortest path from u to v in G but the Bellman-Ford algorithm does. Obviously such a graph must have at least one negative- weight edge.
Consider the following weighted, directed graph G. There are 7 vertices and 10 edges. The edge list E is as follows:The Bellman-Ford algorithm makes |V|-1 = 7-1 = 6 passes through the edge list E. Each pass relaxes the edges in the order they appear in the edge list. As with Dijkstra's algorithm, we record the current best known cost D[V] to reach each vertex V from the start vertex S. Initially D[A]=0 and D[V]=+oo for all the other vertices...
question 1 and 2 please, thank you. 1. In the following graph, suppose that the vertices A, B, C, D, E, and F represent towns, and the edges between those vertices represent roads. And suppose that you want to start traveling from town A, pass through each town exactly once, and then end at town F. List all the different paths that you could take Hin: For instance, one of the paths is A, B, C, E, D, F. (These...
3. Let G=(V.E) be a weighted, directed graph with weight function w: E->{0,1,...,W} for some nonnegative integer W. Modify Dijkstra's algorithm to compute the shorted paths from a given source vertext s in O(WV+E) time. Hint: no path can have a weight larger than VW: use VW buskets, where each busket is a linked list for the vertices having same d value.
