WebLower Bounds for Comparison-Based Sorting: Can we sort faster than O(nlogn) time? We will give an argument that if the sorting algorithm is based solely on making comparisons … Webachieve this bound, we are just saying it is the best possible. Ω(nlogn) Lower Bound for the Sorting Problem We now apply the adversary lower bound technique to the problem of sorting n comparable elements. Notice that there are n! different permutations (and thus solutions) that the sorting algorithm must decide between.

Claim searching … WebLower Bound for Sorting [Adversary Version] Any comparison-based sorting algorithm needs in the worst case Ω(n log n) comparisons to sort n elements. The sorting algorithm needs to decide between n! different permutations of the input data. The adversary maintains a list L of all possible input data that are consistent with the comparisons

WebIn the Decision tree model, the lower bound to be shown is the lower bound of the average length of root-to-leaf paths of an -leaf binary tree (in which each leaf corresponds to a permutation). It would be convinced to say that a balanced full binary tree achieves the minimum of the average length.

WebSep 19, 2012 · To prove the lower bound, count the steps (inserts,deletes and findmins) and use the fact that no matter what code you write it can't be (worst case) faster than O (nlogn) (for comparison sorts). This gives a lower bound, it has to be at least this slow. Share Improve this answer Follow answered Oct 4, 2011 at 10:24 Ishtar 11.5k 1 23 31
