In computer science, merge sort is an efficient, general-purpose, comparison-based sorting algorithm. Most implementations produce a stable sort, which means that the order of equal elements is the ...

Merge sort, described by Sedgewick[1][2], is the most versatile and flexible sort algorithm. Besides being a general sort algorithm, it is deterministic because its performance is O(nlogn) for all ...

If we're looking to optimize well-understood algorithms, like sorting functions, then basing something on existing human code is, at best, going to get you equivalent performance.
