Answer to relevant QuestionsGet part numbers for parts supplied to all projects in London.Modify your algorithm from Exercise 24.3-6 to run in O ((V + E) lg W ) time. (Hint: How many distinct shortest-path estimates can there be in V - S at any point in time?)Show how to express the single-source shortest-paths problem as a product of matrices and a vector. Describe how evaluating this product corresponds to a Bellman-Ford-like algorithm (see Section 24.1).How can the output of the Floyd-War shall algorithm be used to detect the presence of a negative-weight cycle?Suppose that a flow network G = (V, E) has symmetric edges, that is, (u, v) ¬ E if and only if (v, u) ¬ E. Show that the Edmonds-Karp algorithm terminates after at most |V| |E|/4 iterations.
