A top tree is a data structure based on a binary tree for unrooted dynamic trees that is used mainly for various path-related operations. It allows simple divide-and-conquer algorithms . It has since been augmented to maintain dynamically various properties of a tree such as diameter, center and median.
In computer science, weight-balanced binary trees (WBTs) are a type of self-balancing binary search trees that can be used to implement dynamic sets, dictionaries (maps) and sequences. [1] These trees were introduced by Nievergelt and Reingold in the 1970s as trees of bounded balance , or BB[α] trees .

Heavy path decomposition was introduced by Sleator & Tarjan (1983) as part of the amortized analysis of their link/cut tree structure, [2] and by Harel & Tarjan (1984) as part of their data structure for lowest common ancestors, [3] The link/cut tree data structure uses a partition of a dynamic tree into paths that is not necessarily the heavy ...
“This dynamic duo plays a crucial role in promoting satiety, helping you feel fuller for longer.” Plus, adopting a higher-protein diet that incorporates a variety of protein-rich foods, like ...
Forest disturbances are events that cause change in the structure and composition of a forest ecosystem, beyond the growth and death of individual organisms. Disturbances can vary in frequency and intensity, and include natural disasters such as fire, landslides, wind, volcanic eruptions, rare meteor impacts, outbreaks of insects, fungi, and other pathogens, animal-caused effects such as ...
Wildfires in the greater Los Angeles area continued to burn mostly out of control on Thursday, with at least five blazes engulfing more than 45 square miles.. At least 16 people have died as a ...
Widespread destruction from the L.A. fires was inevitable, given the drought and winds. Still, the region could have been better prepared.
