Analysis of Algorithm: Scheduling Problems
Suppose we minimize the average time to store n files of lengths l1, l2, , ln on a tape. If the probability of requesting file k is given by pk, the expected access time to load these n files in the order k1, k2, , kn is given by the formula The constant C represents parameters such as the speed of the drive and the recording density.
(a) In what order should a greedy approach store these files to guarantee minimum average access time?
(b) Write the algorithm that stores the files, analyze your algorithm, and show the results using order notation.
