Left subtree contains only nodes with value less than the node's value. Right subtree contains only nodes with value greater than the node's value. All values in the nodes are unique. Both left and right subtrees are also binary search tree recursively. If there is a new node to be ins...
In this problem, the input is a set of phylogenetic characters, each of which may be viewed as a partition of a subset of species. The goal is to find a phylogenetic tree such that every character is convex on that tree — that is, the parts of each partition form connected subtrees ...
We describe these polynomials for some well-studied families of graphs including paths, stars, cycles, spider graphs, caterpillars, and balanced binary trees. In doing so, we recover connections to independence polynomials, and extend some classical identities that hold for Fibonacci numbers. We also...
In fact, Read applied the Burnside lemma to obtain his counting formula, but this line of ideas, namely finding equivalence classes of graphs under some symmetry groups, dates back even further. One notable result of the 19th century was Cayley’s enumeration of trees, which pioneered ...
Efficient location of fruits in the trees is the most important criterion of an automatic robotic harvesting system. The main challenges faced in the development of the robotic harvesting arm are accurate identification of the fruits in dense foliages and detection of the occluded fruits. This paper...
The main technical component of our solution is based on efficiently storing variable-length bounded binary counters and its analysis via weighted balls-into-bins experiments in which the weight of a ball is logarithmic in its multiplicity.
UsesFork / Joinfor performing analysis on the word counts. Here again the actual mechanism is encapsulated in a generic, reusable implementation. UsesNIO.2for traversing directory trees and reading files. Makes heavy use offunctional interfacesandlambdasin order to pass functions rather than data whe...
IRAST [26] used unlabeled images to achieve more reliable and efficient semi-supervised crowd counting by learning feature extractors and binary segmentation tasks. DACount [25] utilized SSL and integrated strategies such as density proxies, contrastive learning, transformer structure, and noise ...
One can reformulate the condition of a clique-tree having a polynomially bounded number of subtrees as a more local condition on the clique-tree. Among others, this allows us to check in linear time whether a clique-tree has a desired polynomial bound on the number of subtrees or not. ...
