Let the vertex set V= { 1, 2, 3, 4, 5 } and let the edge set R, a relation on V, be given as follows: R = { (1,1), (1,2), (1,3), (2,1), (2,2), (4,3), (3,5), (4,5), (5,4) } (i) Draw a diagram that represents the relation R graphically (using directed graph). Answer: (ii) Fill the following zero-one matrix representation of the relation R. Answer:
Question 9 Create a graph, if possible, with the following attributes, then find the index matrix of your graph. 6 vertices 5 edges One vertex with a degree of 3 All vertices are connected in some way, but it does not have to be a direct connection
Pick the correct statements for the attached directed graph for a toy world wide web. 1. There are exactly six columns having a 1 as an entry. 2. If a new edge from node I to F is added, the resulting graph is strongly connected. 3. The smallest non-zero element in the link matrix is 1/4. 4. The link matrix Q has a column of all zeros. 5. The link matrix is a reducible matrix.
You'd like to study social networks. Consider the following 26 people {A,B,C,...,X,Y,Z} in a social network graph. (These people can be thought of as "nodes" or points drawn on a piece of paper.) Here, we'd like to model "followers." How many different ways can we draw arrows between two people from these 26? Here, "A-->B" (A is a follower of B) is not the same as "B-->A" (B is a follower of A). Order matters here. Enter your answer as a whole number.
It was claimed that anyone involved in the Hollywood film industry can be linked through their film roles to Kevin Bacon within six steps. You are suspicious of such a claim and decide to verify it using the given dataset.1. Before you start to verify the claim, you first notice that it is not possible for this claim to be true if the actor graph is not even connected. Now that you know how to verify if the actor graph defined by the given dataset is connected (the actor graph is indeed connected), explain how can you further verify the claim of "Six Degrees of Kevin Bacon", that is: in the actor graph, each actor/actress is connected to Kevin Bacon with a path that contains no more than 6 edges. You should also include the runtime ofyour algorithm.
A weighted, directed graph is a suitable representation to represent the daily airline routes flown by a small airline. The airline have the following daily flights: - Three flights from Cape Town to Johannesburg, - Two flights from Johannesburg to Cape Town. - Four flights from Johannesburg to Durban. - Three flights from Durban to Johannesburg. - One flight from Johannesburg to George. - One flight from George to Johannesburg.Draw the graph and answer the questions that follow. The graph that represents this problem is connected. A. True B. False
Let A be the towns {P, Q, R, S}. Let B be the one way street relation {(P, S), (Q, P), (R, P), (S, Q), (S, R)}. Find B^2 (pairs of towns that are connected by two streets). Find B3 (pairs of towns that are connected by three streets). You must use directed graph to find the answer.
a) Write the adjacency matrix representing the graph above. b)Would you prefer to represent this graph (specifically the one above) as an adjacency list or as an adjacency matrix? Justify your answer. c) Topological sorting is an algorithm on graphs used to produce a schedule. Assuming each node in this graph represents an item, what is ONE schedule associated with the above graph? If the topological sorting algorithm cannot be run on the above graph, justify your answer.
