InfoBubble sort, sometimes referred to as sinking sort, is a simple sorting algorithm that works by repeatedly stepping through the list to be sorted, comparing each pair of adjacent items and swapping them if they are in the wrong order.more...The pass through the list is repeated until no swaps are needed, which indicates that the list is sorted. The algorithm gets its name from the way smaller elements "bubble" to the top of the list. Because it only uses comparisons to operate on elements, it is a comparison sort. Although the algorithm is simple, it is too slow for practical use, even compared to insertion sort.

It differs in that instead of repeatedly passing through the list from bottom to top, it passes alternately from bottom to top and then from top to bottom.It can achieve slightly better performance than a standard bubble sort.The reason for this is that bubble sort only passes through the list in one direction and therefore can only move items backward one step each iteration.…

It will not be efficient in the case of a reverse-ordered collection.The positions of the elements in bubble sort will play a large part in determining its performance.Large elements at the beginning of the list do not pose a problem, as they are quickly swapped.…

However one cocktail sort pass should be counted as two bubble sort passes.Typically cocktail sort is less than two times faster than bubble sort.Another optimization can be that the algorithm remembers where the last actual swap has been done.…

Shell sort was invented by Donald Shell in 1959.It improves upon bubble sort and insertion sort by moving out of order elements more than one position at a time.One implementation can be described as arranging the data sequence in a two-dimensional array and then sorting the columns of the array using insertion sort.…

This has led to these types of elements being named rabbits and turtles, respectively.Various efforts have been made to eliminate turtles to improve upon the speed of bubble sort.Cocktail sort is a bi-directional bubble sort that goes from beginning to end, and then reverses itself, going end to beginning.…

Bubble sort has been occasionally referred to as a "sinking sort".

However, not only does insertion sort have this mechanism too, but it also performs better on a list that is substantially sorted (having a small number of inversions).Bubble sort should be avoided in the case of large collections.It will not be efficient in the case of a reverse-ordered collection.…

Therefore, bubble sort is not a practical sorting algorithm when n is large.The only significant advantage that bubble sort has over most other implementations, even quicksort, but not insertion sort, is that the ability to detect that the list is sorted is efficiently built into the algorithm.…

In computing, an odd-even sort or odd-even transposition sort (also known as brick sort) is a relatively simple sorting algorithm, developed originally for use on parallel processors with local interconnections.It is a comparison sort related to bubble sort, with which it shares many characteristics.It functions by comparing all (odd, even)-indexed pairs of adjacent elements in the list and, if a pair is in the wrong order (the first is larger than the second) the elements are switched.…

The basic idea is to eliminate turtles, or small values near the end of the list, since in a bubble sort these slow the sorting down tremendously.Rabbits, large values around the beginning of the list, do not pose a problem in bubble sort.In bubble sort, when any two elements are compared, they always have a gap (distance from each other) of 1.…

Unlike in bubble sort, where the gap is constant i.e. 1.The gap starts out as the length of the list being sorted divided by the shrink factor (generally 1.3; see below), and the list is sorted with that value (rounded down to an integer if needed) as the gap.…

Bubble sort the array by comparing adjacent numbers, and swapping them if they are in the wrong order.

Rabbits, large values around the beginning of the list, do not pose a problem in bubble sort.In bubble sort, when any two elements are compared, they always have a gap (distance from each other) of 1.The basic idea of comb sort is that the gap can be much more than 1 (Shell sort is also based on this idea, but it is a modification of insertion sort rather than bubble sort).…

This reduces the number of scans of the list by a factor of 2, eliminating some loop overhead but not actually decreasing the number of comparisons or swaps.Note, however, that cocktail sort more often refers to a bidirectional variant of bubble sort.Selection sort can be implemented as a stable sort.…

For more restricted data, such as numbers in a fixed interval, distribution sorts such as counting sort or radix sort are widely used.Bubble sort and variants are rarely used in practice, but are commonly found in teaching and theoretical discussions.When physically sorting objects, such as alphabetizing papers (such as tests or books), people intuitively generally use insertion sorts for small sets.…

This is so because applying such a transposition reduces the number of inversions by 1; also note that as long as this number is not zero, the permutation is not the identity, so it has at least one descent.Bubble sort and insertion sort can be interpreted as particular instances of this procedure to put a sequence into order.…

Experimental results such as those of Astrachan have also shown that insertion sort performs considerably better even on random lists.For these reasons many modern algorithm textbooks avoid using the bubble sort algorithm in favor of insertion sort.Bubble sort also interacts poorly with modern CPU hardware.…

Cocktail sort, also known as bidirectional bubble sort, cocktail shaker sort, shaker sort (which can also refer to a variant of selection sort), ripple sort, shuffle sort, or shuttle sort, is a variation of bubble sort that is both a stable sorting algorithm and a comparison sort.The algorithm differs from a bubble sort in that it sorts in both directions on each pass through the list.This sorting algorithm is only marginally more difficult to implement than a bubble sort, and solves the problem of turtles in bubble sorts.…
