a-list-of-n-items-is-arranged-in-random-order-to-find-a-requested-item-they-are-searched-sequentiall

A list of $n$ items is arranged in random order; to find a requested item, they are searched sequentially until the desired item is found. What is the expected number of items that must be searched through, assuming that each item is equally likely to be the one requested? (Questions of this nature arise in the design of computer algorithms.)

suppose-you-have-three-different-algorithms-for-solving-the-same-problem-and-each-algorithm-provides

Suppose you have three different algorithms for solving the same problem and each algorithm provides for a number of steps that is of order of one of the functions listed here. $$ n \log _{2} n, n^{3 / 2}, n\left(\log _{2} n\right)^{2} $$ Which of the algorithms is likely the most efficient in the long run? Give reasons for your answer.

00:01 In this problem, we are searching sequentially through a list of n items to find a requested item.
00:08 The n items is arranged in a completely random order, and we assume each item is equally likely to be the one we want to find.
00:19 The question here is, what is the expected number of items we need to search through before we find the requested item? if the requested item turns up in the first place, the number of search is 1.
00:33 If it turns up at the second place, then the number of searches is 2...
