http://xlinux.nist.gov/dads/HTML/optimalMerge.html WebA greedy algorithm is an approach for solving a problem by selecting the best option available at the moment. It doesn't worry whether the current best result will bring the overall optimal result. The algorithm never reverses the earlier decision even if the choice is wrong. It works in a top-down approach.

WebQuestion: Design a greedy algorithm to solve the optimal merge pattern problem. In this problem, we have n sorted files of lengths f0, f1, ..., fn-1, and we wish to merge them into a single file by a sequence of merges of pairs of files. To merge two files of lengths m1 and m2 take m1 + m2 operations. WebOur purpose is to study the optimal way to merge n initially sorted runs, stored on a disk like device, into a unique sorted file. This problem is equivalent to finding a tree with n leaves which minimizes a certain cost function (see Knuth [1]).We ...
