The deterministic selection algorithms with the smallest known numbers of comparisons, for values of that are far from or , are based on the concept of factories, introduced in 1976 by Arnold Schönhage, Mike Paterson, and Nick Pippenger. These are methods that build partial orders of certain … See more In computer science, a selection algorithm is an algorithm for finding the $${\displaystyle k}$$th smallest value in a collection of ordered values, such as numbers. The value that it finds is called the See more Sorting and heapselect As a baseline algorithm, selection of the $${\displaystyle k}$$th smallest value in a collection of values … See more Very few languages have built-in support for general selection, although many provide facilities for finding the smallest or largest element of a list. A notable exception is the See more • Geometric median § Computation, algorithms for higher-dimensional generalizations of medians • Median filter, application of median-finding algorithms in image processing See more An algorithm for the selection problem takes as input a collection of values, and a number $${\displaystyle k}$$. It outputs the $${\displaystyle k}$$th … See more The $${\displaystyle O(n)}$$ running time of the selection algorithms described above is necessary, because a selection algorithm that can handle inputs in an arbitrary order must take that much time to look at all of its inputs; if any one of its input values is not … See more Quickselect was presented without analysis by Tony Hoare in 1965, and first analyzed in a 1971 technical report by Donald Knuth.
