Problem 6. In lecture, we saw that an undirected graph with n nodes can have at most n(n - 1)/2 edges. Such a graph necessarily has one connected component. The greatest number of edges possible in a disconnected graph, however, is smaller. Suppose that G (V, E) is a disconnected graph with n nodes, how large can |El possibly be? You do not need to prove your answer, but you should provide some explanation of how you obtained it.

Problem 2: As we discussed in class, one can use an algorithm for computing all-pairs shortest paths to also compute the transitive closure of a graph. If using Floyd-Warshall for example, it is possible to do this in On") time (where as usual n is the number of nodes and m is the number of edges). Show how to compute the transitive closure of a directed graph in O(nm) time. For which type of graphs is this better than using...

wrote.
To assign vertex names you can write it as
g = graph(edges = c("a", "b", "b", "c"), directed =
FALSE)
or
g = graph(edges = c(1, 2, 2, 3), directed = FALSE)
V(g)$name = c("a", "b", "c")

I can give examples of graphs having combinations of various properties and examples of graphs of special (" named”) types. 1. Draw a graph G with • V(G) = {a,b,c,d,e,f}, • deg(d) = 2, • a and f are neighbors, • {b,d} & E(G), G is simple, • K4 is a subgraph of G. 2. Draw the graph C7. 3.

Who should you trust to give you sound information about nutrition? Why does it seem like there is so much conflicting information out there? How do we know the information is credible? Post a link to an article containing a nutrition claim and indicate whether the source is credible. Also indicate what type of study was done (animal, epidemiological, or clinical trials). What is the role of government in nutrition science?

2. Suppose that we can model the tennis ball market using our standard supply/demand analysis (and that the market price adjusts to keep the market in equilibrium). You read that the market price has increased and the market quantity increased. From this information, we can infer that there was a(n) a. increase (rightward shift) in demand. b. decrease (leftward shift) in demand. c. increase (rightward shift) in both demand and supply. d. increase (rightward shift) in supply. e. decrease (leftward...
