Optimal merge pattern algorithm
WebNov 6, 2024 · We need two merge steps to merge all files. Start with 3 consumers in the first step. The merge sequence ( (1,1,10),10) leads to 12 read/write operations in (inner) step 1 … WebJul 11, 2015 · This technique is used in huffman coding and produces optimal merge pattern. This takes O(m*n*logm). Moreover for similar sized lists it can be made parallel as we can select a pair of list and merge in parallel. Assuming you have m processors then the algorithm can ideally run in O(n*logm) instead of O(m*n*logm) Algorithm 3:-

WebMar 13, 2024 · Greedy algorithms are used to find an optimal or near optimal solution to many real-life problems. Few of them are listed below: (1) Make a change problem (2) Knapsack problem (3) Minimum spanning tree (4) Single source shortest path (5) Activity selection problem (6) Job sequencing problem (7) Huffman code generation. WebApr 8, 2024 · This merge can be performed pair wise. Hence, this type of merging is called as 2-way merge patterns. As, different pairings require different amounts of time, in this strategy we want to determine an optimal way of merging many files together. At each step, two shortest sequences are merged. To merge a p-record file and a q-record file ...
