Alternate Approach of Comparison for Selection Problem

Authors: Nikhil Shaw

This paper proposes an alternate approach to solve the selection problem and is comparable to best-known algorithm of Quickselect. In computer science, a selection algorithm is an algorithm for finding the Kth smallest number in an unordered list or array. Selection is a subproblem of more complex problems like the nearest neighbor and shortest path problems. Previous known approaches work on the same principle to optimize the sorting algorithm and return the Kth element. This algorithm uses window method to prune and compare numbers to find the Kth smallest element. The average time complexity of the algorithm is linear and has the worst case of O(n^2).
