(transitive, computing) To sort with such an algorithm.
Some divide-and-conquer algorithms such as quicksort and mergesort sort by recursively dividing the list into smaller sublists which are then sorted. Source: Internet
If using efficient sorting such as mergesort or heapsort this is an (n log n) average and worst-case algorithm. Source: Internet
LSD radix sorts have resurfaced as an alternative to high performance comparison-based sorting algorithms (like heapsort and mergesort ) that require O(n · log n) comparisons, where n is the number of items to be sorted. Source: Internet
For example, a compiler will not change an implementation of bubble sort to use mergesort instead. Source: Internet
This is faster than performing either mergesort or quicksort over the entire list. Source: Internet
