  • spreadsort is an extremely fast hybrid radix sort algorithm, designed and developed by Steven Ross.
  • pdqsort is a improvement of the quick sort algorithm, designed and developed by Orson Peters.
  • spinsort is a stable sort that is fast with random or nearly sorted data, designed and developed by Francisco Tapia.
  • flat_stable_sort is a stable sort that uses very little additional memory (around 1% of the size of the data), providing 80% - 90% of the speed of spinsort, designed and developed by Francisco Tapia.
