Description

An algorithm seeks to find the $k^{th}$ order statistic of a statistical sample, or the $k^{th}$-smallest value in a list or array.

Parameters

n: size of list

Table of Algorithms

Name Year Time Space Approximation Factor Model Reference
Naive Selection 1940 $O(nlogn)$ $O({1})$ (can use in-situ sorting) Exact Deterministic
Hoare's Selection Algorithm (QuickSelect) 1961 $O(n)$ $O({1})$ (in-situ) Exact Deterministic Time
Hashing 1940 $O(n)$ $O(n)$ Exact Deterministic
