Fast approximation of search trees on trees with centroid trees
, 2022 Search trees on trees (STTs) generalize the fundamental binary search tree (BST) data structure: in STTs the underlying search space is an arbitrary tree, whereas in BSTs it is a path. An optimal BST of size $n$ can be computed for a given distribution of queries in $O(n^2)$ time [Knuth 1971] and centroid BSTs provide a nearly-optimal alternative ...

A PANoptosis‐Based Signature for Survival and Immune Predication in Glioblastoma Multiforme
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective PANoptosis is a concept of total cell death characterized by pyroptosis, apoptosis, and necroptosis. We aimed to explore the clinical significance of PANoptosis‐related genes (PARGs) in glioblastoma multiforme (GBM). Methods Expression profiles of GBM were downloaded from the XENA database as a training dataset to construct a ...

Travel motivations of domestic tourists: The case of Zimbabwe. [PDF]
African Journal of Hospitality, Tourism and Leisure, 2019 The quantity of research on domestic tourism for destinations in Africa is significantly lower than that on international tourism. The paper sought to investigate the motivations of domestic tourists in Zimbabwe with a view to gain greater insights on ...

On bucket increasing trees, clustered increasing trees and increasing diamonds [PDF]
arXiv, 2020 In this work we analyze bucket increasing tree families. We introduce two simple stochastic growth processes, generating random bucket increasing trees of size $n$, complementing the earlier result of Mahmoud and Smythe for bucket recursive trees. On the combinatorial side, we define multilabelled generalizations of the tree families $d$-ary increasing

Game Tree Algorithms and Solution Trees [PDF]
Theoretical Computer Science, 1999 AbstractIn this paper a theory of game tree algorithms is presented, entirely based upon the concept of a solution tree. Two types of solution trees are distinguished: max and min trees. Every game tree algorithm tries to prune as many nodes as possible from the game tree.

From gene trees to species trees II: Species tree inference in the deep coalescence model [PDF]
arXiv, 2010 When gene copies are sampled from various species, the resulting gene tree might disagree with the containing species tree. The primary causes of gene tree and species tree discord include lineage sorting, horizontal gene transfer, and gene duplication and loss.
