The problem of finding a shortest path in a graph can be polynomially reduced to an instance of the integer knapsack problem
Answer)
The problem of finding the shortest
path in a graph can be polynomially
reduced to an instance
of the integer knapsack problem -
True
The Knapsack Problem is the problem in combinational optimization
where a set of items is given and each has a weight and value. Now
given this, the process to determine each item in the collection to
include where the total weight of such selection of items will be
less than or equal to a given limit and the total value is made as
large as possible. In simple words, the weights and the values of n
items are given and from them, we have to select the items which
are in a Knapsack of the max weight which has to get the maximum
total value.

Shortest Path Suppose we are given an instance of the Shortest s-t Path Problem on a directed graph G. We assume that all edge costs are positive and distinct integers. Let P be a minimum-cost s-t path for this instance. Now suppose we replace each edge cost ce by its square, c 2 e, thereby creating a new instance of the problem with the same graph but different costs. For each of the following statements, decide whether it is true...
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 _______ .
Problem E: For each of the following parts, state True or False. If true, give a short proof. If false, givera counterexample: (1). Using Kruskal's algorithm, edges are (always) inserted into the MST in the same order as using Prim's (2). If an edge e is part of a TSP tour found by the quick TSP method then it must also be part of the (3). If an edge e is part of a Shortest Path Tree rooted at A...
Problem 6. (Weighted Graph Reduction) Your friend has written an algorithm which solves the all pairs shortest path problem for unweighted undirected graphs. The cost of a path in this setting is the number of edges in the path. The algorithm UNWEIGHTEDAPSP takes the following input and output: UNWEİGHTEDA PSP Input: An unweighted undirected graph G Output: The costs of the shortest paths between each pair of vertices fu, v) For example, consider the following graph G. The output of...
Question 6 Let G be the weighted graph (a) Use Dijkstra's algorithm to find the shortest path from A to F. You can do all the work on a single diagram, but, to show that you have used the algorithm correctly, if an annotation needs updating do not erase itjust put a line through it and write the new annotation above that b) In what order are the vertices added to the tree? (c) Notice that the algorithm does not,...
linear algebra problem 1. True or False. If true, explain why. If false provide a counterexample. . If A? - B2, then A - B (you can assume that A and B have the same size). • If columns 1 and 3 of B are the same, so are columns 1 and 3 of AB. • If rows 1 and 3 of B are the same, so are rows 1 and 3 of AB. • (AB) - A’B?
