Example text

Specifically, we are given an ordered sequence x1 < x2 < · · · < xn and associated frequencies of access β1 , β2 , . . , βn , respectively; furthermore, we are given α0 , α1 , . . , αn where αi is the frequency with which the search will fail because the object sought, z, was missing from the sequence, xi < z < xi+1 (with the obvious meaning when i = 0 or i = n). What is the optimal order to search for an unknown element z? In fact, how should we describe the optimal search order? We express a search order as a binary search tree, a diagram showing the sequence of probes made in every possible search.

The basic idea is to store the key x in location T[h(x)]. Typically, hash functions are chosen so that they generate “random looking” values. For example, the following is a function that usually works well: h(x) = x mod m where m is a prime number. The preceding function assumes that x is an integer. In most practical applications, x is a character string instead. , using the American Standard Code for Information Interchange (ASCII) coding). If a string x can be written as ck ck−1 , . . , c1 c0 , where each ci satisfies 0 ≤ ci < C, then we can compute h as h ← 0; for i in 0, .

Algorithm Design and Analysis Techniques 1-25 Information theoretic lower bounds do not always give useful results. Consider the element uniqueness problem, the problem of determining if there are any duplicate numbers in a set of n numbers, x1 , x2 , . . , xn . Since there are only two possible outcomes, yes or no, the information theoretic lower bound says that a single comparison should be sufficient to answer the question. 4) 1≤i
