The SortingAlgorithms package provides four sorting algorithms that can be used with Julia's standard sorting API:
- HeapSort – an unstable, general purpose, in-place, O(n log n) comparison sort that works by heapifying an array and repeatedly taking the maximal element from the heap.
- TimSort – a stable, general purpose, hybrid, O(n log n) comparison sort that adapts to different common patterns of partially ordered input data.
- CombSort – an unstable, general purpose, in-place, O(n log n) comparison sort with O(n^2) pathological cases that can attain good efficiency through SIMD instructions and instruction level parallelism on modern hardware.
- PagedMergeSort – a stable, general purpose, O(n log n) time and O(sqrt n) space comparison sort.
