Common Sorting Algorithms In this article, we review the most commonly used sorting algorithms, their complexities, and practical applications in custom software and artificial intelligence projects.
Bubble Sort Runtime O(n²) average and worst case. Memory O(1). Description: the array is traversed, swapping adjacent elements if they are out of order, performing successive passes until the smallest elements emerge to the beginning. Suitable for very small or educational datasets but inefficient for large data.
Selection Sort Runtime O(n²) average and worst case. Memory O(1). Description: in each pass, the minimum element is located through a linear scan and placed at the front via a swap. Repeat for each position until the entire array is sorted. Simple and unstable, with limited use in production applications.
Merge Sort Runtime O(n log n) average and worst case. Variable memory. Description: divide and conquer. The array is divided into halves, each half is sorted recursively, and then they are merged while maintaining order. The merge phase uses an auxiliary structure to efficiently combine both halves. It is stable and widely used when guaranteed performance is required.
Quick Sort Runtime O(n log n) average, O(n²) worst case. Memory O(log n) on average. Description: it selects a pivot, partitions the array into values less than and greater than the pivot, and applies the same procedure recursively. With good pivot selection and partitioning heuristics, it is one of the fastest in practice.
Radix Sort Runtime O(k n). Description: a non-comparative algorithm for integers and types with finite representation. It sorts by successive digits or positions, grouping by each digit and repeating the process k times, where k is the number of digits. It can surpass the O(n log n) bound of comparison-based algorithms when k is small relative to n.
