  2. Selection sort - Wikipedia

    en.wikipedia.org/wiki/Selection_sort

    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.

  3. Selection algorithm - Wikipedia

    en.wikipedia.org/wiki/Selection_algorithm

    The time for this method is dominated by the sorting step, which requires (⁡) time using a comparison sort. [ 2 ] [ 3 ] Even when integer sorting algorithms may be used, these are generally slower than the linear time that may be achieved using specialized selection algorithms.

  4. Sorting algorithm - Wikipedia

    en.wikipedia.org/wiki/Sorting_algorithm

    Selection sort is an in-place comparison sort. It has O(n 2) complexity, making it inefficient on large lists, and generally performs worse than the similar insertion sort. Selection sort is noted for its simplicity and also has performance advantages over more complicated algorithms in certain situations.

  5. Time complexity - Wikipedia

    en.wikipedia.org/wiki/Time_complexity

    Graphs of functions commonly used in the analysis of algorithms, showing the number of operations N as the result of input size n for each function. In theoretical computer science, the time complexity is the computational complexity that describes the amount of computer time it takes to run an algorithm. Time complexity is commonly estimated ...

  6. Online algorithm - Wikipedia

    en.wikipedia.org/wiki/Online_algorithm

    As an example, consider the sorting algorithms selection sort and insertion sort: selection sort repeatedly selects the minimum element from the unsorted remainder and places it at the front, which requires access to the entire input; it is thus an offline algorithm. On the other hand, insertion sort considers one input element per iteration ...

  8. Quicksort - Wikipedia

    en.wikipedia.org/wiki/Quicksort

    This change lowers the average complexity to linear or O(n) time, which is optimal for selection, but the selection algorithm is still O(n 2) in the worst case. A variant of quickselect, the median of medians algorithm, chooses pivots more carefully, ensuring that the pivots are near the middle of the data (between the 30th and 70th percentiles ...
