Array sort: an adaptive sorting algorithm on multi-thread

Comparison-based sorting algorithms have traditionally dealt with achieving an optimal bound of O(n log n) when dealing with time complexity. Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence. In other words, the more presorted the input is, the faster it should be sorted. WitrynaThey perform better when the input is sorted. Merge sort is not adaptive because it uses O(N log N) comparisons even when the input is already sorted. 3. Is merge … how to repaint a shelf

WitrynaRotate merge sort A rotate merge sort uses rotations to partition two sorted arrays until they're small enough to be merged using auxiliary memory. Blitsort does so by taking the center element of the first array, using a binary search to find all elements smaller than the center element in the second array, and performing an array rotation.
