Pairwise sorting network

The pairwise sorting network is a sorting network discovered and published by Ian Parberry in 1992 in Parallel Processing Letters. The pairwise sorting network has the same size (number of comparators) and depth as the odd–even mergesort network. At the time of publication, the network was one of several known networks with a depth of . It requires comparators and has depth . The sorting procedure implemented by the network is as follows (guided by the zero-one principle): 1. * Sort consecutive pairwise bits of the input (corresponds to the first layer of the diagram) 2. * Sort all pairs into lexicographic order by recursively sorting all odd bits and even bits separately (corresponds to the next 14 layers of the diagram) 3. * Sort the pairs in nondecreasing order using a specialized network (corresponds to the final layers of the diagram) (Wikipedia).

Merge Sort 1 – The Algorithm

This is the first in a series of videos about the merge sort. It describes the principle of the merge sort algorithm, which takes a ‘divide and conquer’ approach to the problem of sorting and unordered list. The videos that follow build on these principles, leading towards a recursive im

Merge Sort 4 – Towards an Implementation (Recursive Function)

This is the fourth in a series of videos about the merge sort. It includes a description of some pseudocode which combines into a single recursive function a helper program for splitting a list, and a helper program for merging a pair of ordered lists. This video describes how successive

Quicksort 2 – Alternative Algorithm

This video describes the principle of the quicksort, which takes a ‘divide and conquer’ approach to the problem of sorting an unordered list. In this particular algorithm, the approach to partitioning a list does not rely on the explicit nomination of a pivot value, but still makes use of
