Pairwise Sorting Network
Pairwise Sorting Network Pairwise sorting network is a comparison sorting algorithm defined as a fixed network of compare and swap operations. It performs sorting through a sequence of pairwise comparisons arranged in stages. Unlike adaptive algorithms, its structure does not depend on input values. This makes it suitable for parallel execution and hardware implementation. Problem Given an array $A$ of length $n$, reorder it such that: $$ A[0] \le A[1]...
