Introsort or introspective sort is a hybrid sorting algorithm that provides both fast average performance and (asymptotically) optimal worst-case performance...

insertion sort, and additional logic), used in Android, Java, and Python, and introsort (quicksort and heapsort), used (in variant forms) in some C++ sort implementations...

performance and optimal worst-case performance. Introselect is related to the introsort sorting algorithm: these are analogous refinements of the basic quickselect...

required to avoid bad pivot choices and the resultant O(n2) performance. Introsort is a variant of quicksort which solves this problem by switching to heapsort...

Library (STL). In Musser (1997), he developed the sorting algorithm called introsort (also known as introspective sort), and the related selection algorithm...

quicksort, which is fast in practice but has poor worst-case performance, but introsort was introduced to allow both fast average performance and optimal worst-case...

for example, uses a 3-part hybrid sorting algorithm: introsort is performed first (introsort itself being a hybrid of quicksort and heap sort), to a...

complexity. Another example of hybrid algorithms for performance reasons are introsort and introselect, which combine one algorithm for fast average performance...

makes their implementation far more complex, and implementations such as introsort and pattern-defeating quicksort use heapsort as a last-resort fallback...

performance of spreadsort is O(n log n) for small data sets, as it uses introsort as a fallback. In the case of distributions where the size of the key...
