In the Given graph G=(V, E), find Shortest paths among all pairs of vertices by using Floyed Warshall Algorithm. V={a, b, c, d, e} and E={(a, b, 3), (a, c, 8), (a, e, 4), (b, d, 1), (b, e, 7), (b, c, 4), (d, c, -5), (d, b, 6), (d, a, 2), (e, d, 6)}. Note: Numeric value is the weight of the corresponding edge.
Consider a graph with five nodes labeled A, B, C, D, and E. Let's say we have the following edges with their weights: A to B with weight 3 A to C with weight 1 B to C with weight 2 B to D with weight 1 C to E with weight 4 D to E with weight 2 a. Find the shortest path from A to E using Dijkstra's algorithm b. Use Prim to find the MST c. Use Kruskal to find the MST d. What's the difference between Prim and Kruskal algorithms? Do they always have the same result? Why or why not.

The questions below assume weighted undirected graphs with distinct edge weights. True or False: The highest cost edge in a graph cannot be in an MST. If true, prove it. If false, show an example in which it is included.True or False: The highest cost edge in a cycle within a graph cannot be in an MST. If true, prove it. If false, show an example in which it is included. Give an example of a graph in which the highest weighted edge will not be in the MST, but will be in a shortest path tree from a given node when running Dijkstra’s algorithm. Note: you need to provide the graph with all weights, and select a source node for Dijkstra that will include the highestweighed edge.
(1) Given a weighted directed graph G = (V, E, w), where V = {1, 2, 3, 4}, E ={(1,3), (2,1), (2,4), (3,2), (4,1), (4,3)}, and w(1,3) = −2, w(2,1) = 1, w(2,4) = 2,w(3,2) = 4, w(4,1) = −3, w(4,3) = 3. (a) Represent the graph G graphically;(b) Run SLOW-ALL-PAIRS-SHORTEST-PATHS on the above graph and show the matricesL(k) that result for each iteration of the loop. (2) Discuss how to use the Floyd-Warshall algorithm to detect a negative-weight cycle. (3) The essence of Johnson’s algorithm is re-weighting so that a transformed graph has no negativeweight edges, which enables the use of Dijkstra’s algorithm.

From the chart, estimate (roughly) the number of transistors per IC in 2016. Using your estimate and Moore's Law, what would you predict the number of transistors per IC to be in 2040? In some applications, the variable being studied increases so quickly ("exponentially") that a regular graph isn't informative. There, a regular graph would show data close to 0 and then a sudden spike at the very end. Instead, for these applications, we often use logarithmic scales. We replace the y-axis tick marks of 1, 2, 3, 4, etc. with y-axis tick marks of 101 = 10, 102 = 100, 103 = 1000, 104 = 10000, etc. In other words, the logarithms of the new tick marks are equally spaced. Technology is one area where progress is extraordinarily rapid. Moore's Law states that the progress of technology (measured in different ways) doubles every 2 years. A common example counts the number of transitors per integrated circuit. A regular y-axis scale is appropriate when a trend is linear, i.e. 100…
Question 1: In graph theory, a graph X is a "complement" of a graph F if which of the following is true? Select one: a. If X is isomorph to F, then X is a complement of F. b. If X has half of the vertices of F (or if F has half of the vertices of X) then X is a complement of F. c. If X has the same vertex set as F, and as its edges ONLY all possible edges NOT contained in F, then X is a complement of F. d. If X is NOT isomorph to F, then X is a complement of F.
