Question

Consider the first image, a weighted directed network with nodes named A, B, C, D, E, F :

  1. Which of the following most accurately describes the connectedness of this network?
    1. Strongly
    2. Weakly
    3. Disconnected
    4. None of the
  2. What is the in-strength of node D? What is the out-strength of node C?
  3. How many nodes are in the largest strongly connected component?

Consider the second network numbered from 1 to 6: 

  1. Which of the following most accurately describes the connectedness of this network?
    1. Strongly
    2. Weakly
    3. Disconnected
    4. None of the
  2. When discussing path lengths on a weighted graph, one must first define how the weights are related to the length of a path between two nodes is then the sum of the distances of the links in that path. Consider the previous network and assume that the link weights represent distances. Using this distance metric, what is the shortest path between nodes 1 and 6?
