Assignment Help Basic Computer Science
Reference no: EM133269891

In Exercise 5.40 we described an O(n ^ 2) method for updating shortest path distances between all-pairs of nodes when we decrease the length of one arc (p, q) Suppose that we increase the length of the arc (p, q) Can you modify the method so that it reoptimizes the shortest path distances in O(n ^ 2) time? If your answer is yes, specify an algorithm for performing the reoptimization and provide a justification for it; and if your answer is no, outline the difficulties encountered.
