Divide-and-Conquer: Transcript

CS 46101 Section 600 CS 56101 Section 002 Dr Angela Guercio Spring 2010 Analyzing DivideandConquer Algorithms Use a recurrence to characterize the running time of a divideandconquer algorithm. The structure of a divideandconquer algorithm applied to a given problem has the following form Base Case When the instance of the problem is suf64257ciently small return the answer directly or resort to a different usually simpler algorithm that is n where Observe, that the number of subproblems is not necessarily equal to . The total numberof steps is obtained by all steps needed to solve smaller subproblems plus thenumber needed to combi Abhishek Mukherji, . Professor Elke . A. . Rundensteiner, Professor Matthew O.
