Polska Akademia Nauk}, publisher={Systems Research Institute. Polish Academy of Sciences}, language={eng}, abstract={The paper shows that several versions of Floyd and Rivest’s improved algorithm SELECT for finding the kth smallest of n elements require at most n + min\{k, n — k\} +O (n1/2ln1/2n) comparisons on average and with high probability. This rectifies the analysis of Floyd and Rivest, and extends it to the case of nondistinct elements. Encouraging computational results on large median-finding problems are reported.}, title={Improved Randomized Selection}, type={Text}, URL={http://rcin.org.pl/Content/139616/PDF/RB-2004-67.pdf}, keywords={Medians, Computational complexity, Selection}, }
