A stable sorting algorithm ensures that items that are equal to each other aren't reordered during the sorting process. For instance, suppose we're sorting a list of computer science majors by their grade point average. [('Mia', 3.9), ('Andrey', 3.2), ('Yvette', 3.9), ('Theo',...
Starting with ES10, the specification explicitly states that the Array.prototype.sort() method sorting algorithm must be stable (i.e. elements that compare equal must remain in their original order): // ES10+ const ratings = [ { name: 'foo', rating: 4 }, { name: 'bar', rating: ...

In order to grasp the functionality of stable_sort, it is important to understand what a stable sorting algorithm is. A stable sort preserves the original order of equal elements in a list, ensuring their relativepositions are unchanged after the sort. This is especially useful when sorting data...
Stable Sorting in Swift The Swift sort has long been stable, but the documentation didn't align with the fact. The documentation mentioned that the sorting algorithm is not guaranteed to be stable. The documentation mentioned that the sorting algorithm is not guaranteed to be stable. In Swift...

Glidesort is a novel stable sorting algorithm that combines the best-case behavior of Timsort-style merge sorts for pre-sorted data with the best-case behavior of pattern-defeating quicksort for data with many duplicates. It is a comparison-based sort supporting arbitrary comparison operators, and...
Here are two applications: keap-based PriorityQueue as a replacement of java.util.PriorityQueue and Keapsort sorting algorithm. Both might be useful in two cases: stability is a must; comparing elements is rather heavyweight operation (e.g., it requires a database access). PriorityQueue PriorityQu...
不当的枢轴选择,导致不当的分割,导致Quick Sort恶化为O(N^2)。Introspective Sorting。其行为在大部分情况下几乎与 median-of-3 Quick Sort完全相同。但是当分割行为(partitioning)有恶化为二次行为倾向时,能自我侦测,转而改用Heap Sort,使效率维持在O(NlogN)。SGI中sort使用的就是IntroSort。
