  2. Bubble sort - Wikipedia

    en.wikipedia.org/wiki/Bubble_sort

    For example, it is used in a polygon filling algorithm, where bounding lines are sorted by their x coordinate at a specific scan line (a line parallel to the x axis) and with incrementing y their order changes (two elements are swapped) only at intersections of two lines. Bubble sort is a stable sort algorithm, like insertion sort.

  3. Selection sort - Wikipedia

    en.wikipedia.org/wiki/Selection_sort

    In the bingo sort variant, items are sorted by repeatedly looking through the remaining items to find the greatest value and moving all items with that value to their final location. [2] Like counting sort, this is an efficient variant if there are many duplicate values: selection sort does one pass through the remaining items for each item ...

  4. Sorted array - Wikipedia

    en.wikipedia.org/wiki/Sorted_array

    Sorted arrays are the most space-efficient data structure with the best locality of reference for sequentially stored data. [citation needed]Elements within a sorted array are found using a binary search, in O(log n); thus sorted arrays are suited for cases when one needs to be able to look up elements quickly, e.g. as a set or multiset data structure.

  5. Cocktail shaker sort - Wikipedia

    en.wikipedia.org/wiki/Cocktail_shaker_sort

    An example of a list that proves this point is the list (2,3,4,5,1), which would only need to go through one pass of cocktail sort to become sorted, but if using an ascending bubble sort would take four passes. However one cocktail sort pass should be counted as two bubble sort passes.

  6. Sorting algorithm - Wikipedia

    en.wikipedia.org/wiki/Sorting_algorithm

    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. The worst-case time complexity of Shellsort is an open problem and depends on the gap sequence used, with known complexities ranging from O ( n 2 ) to O ( n 4/3 ) and Θ( n log 2 n ).

  7. Timsort - Wikipedia

    en.wikipedia.org/wiki/Timsort

    Timsort is a stable sorting algorithm (order of elements with same key is kept) and strives to perform balanced merges (a merge thus merges runs of similar sizes). In order to achieve sorting stability, only consecutive runs are merged. Between two non-consecutive runs, there can be an element with the same key inside the runs.

  8. Flashsort - Wikipedia

    en.wikipedia.org/wiki/Flashsort

    The clever part is the elimination of one of those variables, allowing twice as many buckets to be used and therefore half as much time spent on the final O(n 2) sorting. To understand it with two variables per bucket, assume there are two arrays of m additional words: K b is the (fixed) upper limit of bucket b (and K 0 = 0), while L b is a ...

  9. Merge sort - Wikipedia

    en.wikipedia.org/wiki/Merge_sort

    In computer science, Merge Sort (also commonly spelled as mergesort and as merge-sort [2]) is an efficient, general-purpose, and comparison-based sorting algorithm.Most implementations produce a stable sort, which means that the relative order of equal elements is the same in the input and output.
