Lower bounds for sorting
WebFeb 9, 2024 · The array can be sorted in O ( n log log n). There is a lower bound of Ω ( n log log n) for sorting A using comparisons. The general idea is more important than details for both assertions. data-structures time-complexity sorting comparison Share Cite Follow edited Feb 9, 2024 at 9:47 Yuval Filmus 273k 26 301 492 asked Feb 9, 2024 at 9:21 juleand WebWeek 5: Lower Bounds for Comparison-Based Sorting Sorting lower bound: •Comparison-based sort: keys can be (2-way) compared only ! •This lower bound argument considers only the comparison-based sorting algorithms.

http://staff.ustc.edu.cn/~csli/graduate/algorithms/book6/chap09.htm WebThe lower bound of the comparison based sorting algorithm is nlog 2 n. Suppose, We have an input sequence {a 1 ,a 2 ...a n } and assume that all inputs are distinct. We may perform comparison ai <= aj & ai > aj between two elements a i and a j. Here, which pair will make a comparison depends only on the results of the comparisons made so far.

WebFeb 16, 2012 · Any comparison-based sorting algorithm to sort S must take (n lg k) time in the worst case. Proof First notice that, as pointed out in the hint, we cannot prove the lower bound by multiplying together the lower bounds for sorting each subsequence. That would only prove that there is no faster algorithm that sorts the subsequences independently.
