Q2:
Recall the problem of finding the median of an array of an unsorted list.
How fast can one complete the median? What is the recurrence relation that the algorithm follows? (Do not state the algorithm or solve the recurrence relation)
This assignment is an exercise in finding the average-case complexity of an algorithm.Rather than looking at how long an algorithm can run in the worst case as in worst-case analysis, we are looking at how long an algorithm runs on average. This is doneby computing the average number of comparisons and operations executed until thealgorithm ends.Bogosort is a sorting algorithm that orders a list in increasing order by taking thelist, checking to see if the list is ordered increasingly, if the list is not ordered increasinglythen the list is randomly shuffled, and then repeating this process until the list is orderedincreasingly.Expressed in pseudocode:Algorithm 1 BogosortRequire: list: a1, a2, . . . , an of real numbersEnsure: list is sorted in increasing order1: procedure bogo(list)2: while not sorted(list) do ▷ Checks to see if list is sorted3: shuffle(list) ▷ Shuffle the current list if not sorted4: end while5: end procedure
