WebNov 20, 2014 · The root cause of the algorithm unstability lies on the swap instruction. If we want to make it stable, then we can modify the swap. On the default implementation, Selection Sort is using one array, thus O (n) space complexity. Instead of doing swapping, we can use two arrays. We are trading stability for memory space.

"WebApr 21, 2024 · Note: Sorting can be done in place by swapping the least remaining item with the item in the next position to be filled. However, this implementation of the algorithm is not stable. If the (first) least remaining item is inserted, that is, all intervening items moved down (instead of swapping), this algorithm is stable. " - Selection sort not stable

WebMar 7, 2024 · The algorithm behind selection sort is fairly simple, and follows these steps: The minimum element in the unsorted array is found and swapped with the first element, in index 0. The unsort array is then traversed to find the new minimum element. If any element is found to be smaller than the element in index 0, the elements are swapped. WebJun 25, 2024 · Summary. Selection Sort is an easy-to-implement, and in its typical implementation unstable, sorting algorithm with an average, best-case, and worst-case time complexity of O (n²).
