Enhancing and Optimization Sorting Algorithms: An Empirical Study
Abstract. Sorting algorithms are used to sort a list of data. Also sorting is used in other computer operations such as searching, merging, and normalization. Since the sorting is considered as a one of the key operation in computer science, recognition of an optimization approaches can develop this science considerably. Optimization in the sorting algorithms, even in small scale, can cause saving a lot of time. The main discussion of the paper is on those algorithms which present optimized versions of classical sort algorithms. We studied classical and optimized methods some of sorting algorithm such as Selection sort, Bubble sort, Insertion sort, Quick sort and Heap sort and compared each algorithm in terms of the running times when used for sorting arrays of integers.
