WebJun 18, 2024 · An optimal merge pattern corresponds to a binary merge tree with minimum weighted external path length. The function tree algorithm uses the greedy rule to get a … 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 and 22 operations in (outer) step 2, making a total of 34 ops. The sequence (1, (1,10,10)) is even worse with 21+22=43 ops. circularity icon https://thebrickmillcompany.com
