Sentence examples for using a hierarchical tree from inspiring English sources

The gravitational forces are calculated using a hierarchical tree algorithm, while the gasdynamic properties are determined by smoothed particle hydrodynamics.

However, when adapting the FMM to the inhomogeneity of stellar systems and the low force accuracy required in collisionless dynamics (by using a hierarchical tree data structure and a flexible opening angle), it is substantially faster than the tree code (Dehnen [2000], [2002]).

Like the tree code, my FMM implementation uses a hierarchical tree of spatial cells.

An adaptive FMM algorithm also uses a hierarchical tree data structure.

The "rnpB database" uses a hierarchical tree structure, consisting of 5 tables, implementing preorder tree traversal algorithm to process the query efficiently.

In order to estimate the phylogenetic diversity of communities sampled within and between sites, we constructed a species-level phylogenetic tree using a hierarchical approach involving three steps described below: 1) compilation of a genus-level tree, 2) compilation of a species-level tree for each of the included genera, and 3) grafting the species-level trees onto the genus-level tree.

Efforts were made to scale up the number of categories using a hierarchical, branch-and-bound decision tree, with limited success.

Texture and outline features and the SVMLSM algorithm were used to design a hierarchical tree classification system.
