Webdetermine an optimal (i.e., one requiring the fewest comparisons) way to pair wise merge ‘n’ sorted files together. This type of merging is called as 2-way merge patterns. To merge an n-record file and an m-record file requires possibly n + m record moves, the obvious choice choice is, at each step merge the two smallest files together. The

WebOct 23, 2024 · Greedy algorithms are used to find an optimal or near-optimal solution to many real-life problems. A few of them are listed below : Binary Knapsack Problem Fractional Knapsack Problem Job Scheduling Problem Activity Selection Problem Huffman Coding Optimal Storage on Tapes Optimal Merge Pattern Prim’s Algorithm Kruskal’s … WebA greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem. Greedy algorithms are quite successful in some problems, such as Huffman encoding which is used to compress data, or Dijkstra's algorithm, …

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. Weboptimal merge (algorithm) Definition:Mergen sorted sequences of different lengths into one output while minimizing reads. Only two sequences can be merged at once. At each step, the two shortest sequences are merged. Formal Definition:Let D={n1, … , nk} be the set of lengths of sequences to be merged.
