Abstract
AbstractWe present two deterministic parallel Selection algorithms for distributed memory machines, under the coarse‐grained multicomputer model. Both are based on the use of two weighted 3‐medians, that allows discarding at least 1/3 of the elements in each iteration. The first algorithm slightly improves the current experimentally fastest algorithm by Saukas and Song where at least 1/4 of the elements are discarded in each iteration, while the second one is a fast, special purpose algorithm working for a particular class of input, namely an input that can be sorted in linear time using RadixSort.
