WebMar 19, 2024 · Given n number of sorted files, the task is to find the minimum computations done to reach the Optimal Merge Pattern. ... WebGreedy algorithms build a solution part by part, choosing the next part in such a way, that it gives an immediate benefit. This approach never reconsiders the choices taken previously. This approach is mainly used to solve optimization problems. Greedy method is easy to implement and quite efficient in most of the cases.

WebSee also simple merge, ideal merge, Huffman coding, greedy algorithm. Note: Merging sequences by length is the same as joining trees by frequency in Huffman coding. For example, let there be a set of sorted sequences of the following lengths: D={3,5,7,9,12,14,15,17}. Building the optimal merge tree goes as follows. WebHence, the second merge pattern is faster than the first. A greedy attempt to obtain an optimal merge pattern is easy to formulate. Since merging an n-record file and an m-record file requires possibly n +m record moves, the obvious choice for a selection criterion is: at each step merge the two smallest size files together. how to return tabs in edge northeast mountaineering bunkhouse

IMO to minimize the number of reads, the algorithm should try to merge up to k smallest nearby files first, say (10, (1,1), 10, (2,2)). Have a look at dynamic programming for a general approach. To start with the smallest files is generally a good idea.
