Heap Sort Algorithm for sorting in increasing order: Build a max heap from the input data. At this point, the largest item is stored at the root of the heap. Replace it with the last item of the heap followed by reducing the size of heap by 1. Finally, heapify the root of tree. R...
Stooge sort (Stack sort[1], Wandering sort[2]) is a recursive sorting algorithm with time complexity {\displaystyle O(n^{\log _{1{,}5}{3)))\approx O( n^{2.71})}O(n^{{\log _{{1{,}5}}{3}}})\approx O(n^{{2.71}}). The running time of the algorithm is thus extremely ...

Moreover it was proved that any sorting method which uses comparisons on a array of size n must make at least O(nlogn) comparisons. In this paper, we present a new sorting algorithm named hash sort and compared it with the existing algorithms by experiments. The results clearly show that ...
Most have O(nlogn) time complexity. Non-Comparison-Based Algorithms: Utilize specialized techniques, often correlated with specific data types. While faster, they are more restricted in their applications. Quick Overview of Sorting Algorithms AlgorithmAverage Case ComplexityWorst Case ComplexitySpace ...

It is shown that an array of n elements can be sorted using O(1) extra space, O(nlogn/loglogn) element moves, and nlog2n+O(nloglogn) comparisons. This is the first in-place sorting algorithm requiring o(nlogn) moves in the worst case while guaranteeing O(nlogn) comparisons, but ...
We describe and analyze Zig-zag Sort--a deterministic data-oblivious sorting algorithm running in O(n log n) time that is arguably simpler than previously known algorithms with similar properties, which are based on the AKS sorting network. Because it is data-oblivious and deterministic, Zig-zag...
There are many existing sequential algorithm which is a good starting point: O(n2): Bubble sort, Insertion sort etc. O(nlogn): Heap Sort, Merge Sort, etc. Insertion sort: Pick an element and insert it to the right place. Bubble sort: compare pairwise, let the bubble goes up until it...
6. Algorithm Analysis In general, the Quicksort algorithm has an average-case time complexity of O(n*log(n)) and worst-case time complexity of O(n2). With a high density of duplicate keys, we almost always get the worst-case performance with the trivial implementation of Quicksort. ...
