In computer science, smoothsort is a comparison-based sorting algorithm.A variant of heapsort, it was invented and published by Edsger Dijkstra in 1981. [1] Like heapsort, smoothsort is an in-place algorithm with an upper bound of O(n log n) operations (see big O notation), [2] but it is not a stable sort.
Sorting algorithms are prevalent in introductory computer science classes, where the abundance of algorithms for the problem provides a gentle introduction to a variety of core algorithm concepts, such as big O notation, divide-and-conquer algorithms, data structures such as heaps and binary trees, randomized algorithms, best, worst and average ...
In computer science, selection sort is an in-place comparison sorting algorithm. It has a O ( n 2 ) time complexity , which makes it inefficient on large lists, and generally performs worse than the similar insertion sort .
Cocktail shaker sort, [1] also known as bidirectional bubble sort, [2] cocktail sort, shaker sort (which can also refer to a variant of selection sort), ripple sort, shuffle sort, [3] or shuttle sort, is an extension of bubble sort. The algorithm extends bubble sort by operating in two directions.

The algorithm is defined as follows: If the value at the start is larger than the value at the end, swap them. If there are three or more elements in the list, then: Stooge sort the initial 2/3 of the list; Stooge sort the final 2/3 of the list; Stooge sort the initial 2/3 of the list again
Proportion extend sort was published by Jing-Chao Chen in 2001 [2] as an improvement on his earlier proportion split sort design. [3] Its average-case performance, which was only experimentally measured in the original paper, was analyzed by Richard Cole and David C. Kandathil in 2004 [4] and by Chen in 2006, [5] and shown to require log 2 n + O(n) comparisons on average.
Strand Sort Animation. Strand sort is a recursive sorting algorithm that sorts items of a list into increasing order. It has O(n 2) worst-case time complexity, which occurs when the input list is reverse sorted. [1] It has a best-case time complexity of O(n), which occurs when the input is already sorted.
