20.500.12556/DKUM-49394 Computing quadratic entropy in evolutionary trees We note here that quadratic entropy, a measure of biological diversity introduced by Rao, is a variant of the weighted Wiener index, a graph invariant intensively studied in mathematical chemistry. This fact allows us to deduce some efficient algorithms for computing the quadratic entropy in the case of given tip weights, which may be useful for community biodiversity measures. Furthermore, on ultrametric phylogenetic trees, the maximum of quadratic entropy is a measure of pairwise evolutionary distinctness in conservation biology, introduced by Pavoine. We present an algorithm that maximizes this quantity in linear time, offering a significant improvement over the currently used quadratic programming approaches. teorija grafov evolucijsko drevo filogenetsko drevo Wienerjev indeks graph theory evolutionary tree phylogenetic tree quadratic entropy originality distinctness Wiener index true false false Angleški jezik Angleški jezik Delo ni kategorizirano 2015-07-10 12:03:01 2015-07-10 12:03:01 2022-05-27 03:09:32 2019-07-10 21:28:52 2011 0 0 str. 1-18 št. 1160 Vol. 49 2011 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2232-2094 519.17:54 15706713 16009817 URN:SI:UM:DK:UHLN2RDN http://www.imfm.si/preprinti/PDF/01160.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=73953 Fakulteta za naravoslovje in matematiko 0 0 0
