 - [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 is very efficient for primitieve types and orders due to SIMD instructions and instruction level paralellism on modern hardware.
+- [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 paralellism on modern hardware.
