16Patterns of AlgorithmsThis chapter presents several fundamental topics related to the theory of algorithmsalgorithms. These include dynamic programming (Section 16.1), randomized algorithms(Section 16.2), and the concept of a transform (Section 16.3.5). Each ofthese can be viewed as an example of an “algorithmic pattern” that is commonlyused for a wide variety of applications. In addition, we will discuss a numberof numerical algorithms in Section 16.3. Section 16.2 on randomized algorithmspresents the Skip List (Section 16.2.2). The Skip List is a probabilistic data structurethat can be used to implement the dictionary ADT. The Skip List is comparablein complexity to the BST, yet often outperforms the BST, because the Skip List’sefficiency is not tied to the values of the dataset being stored.16.1 Dynamic ProgrammingConsider again the recursive function for computing the nth Fibonacci number.int Fibr(int n) {if (n
532 Chap. 16 Patterns of AlgorithmsIf we could eliminate this redundancy, the cost would be greatly reduced. The approachthat we will use can also improve any algorithm that spends most of its timerecomputing common subproblems.One way to accomplish this goal is to keep a table of values, and first check thetable to see if the computation can be avoided. Here is a straightforward exampleof doing so.int Fibrt(int n, int* Values) {// Assume Values has at least n slots, and all// slots are initialized to 0if (n
