Graphs That are Almost Binary Trees

SIAM Journal on Computing, 1982
This paper studies embeddings of graphs in binary trees. The cost of such an embedding is the maximum distance in the binary tree between images of adjacent graph vertices. Several techniques for bounding the costs of such embeddings from above are derived; notable among these is an algorithm for embedding any outerplanar graph in a binary tree with a ...

Morphing Binary Trees

1994
We investigate the problem of transforming one binary tree into another by rotatoins, subject to certain weight ocnstraints on the nodes of the trees. These constraints arise in the problem of "morphing" one simple polygon to another simple polygon by continuous deformatinos (translations and scalings) that preserve the turn angles and the simplicity ...

Binary-Tree Histograms with Tree Indices

2002
In many application contexts, like statistical databases, transaction recording systems, scientific databases, query optimizers, OLAP, and so on, data are summarized as histograms of aggregate values. When the task of reconstructing range queries on original data from aggregate data is performed, a certain estimation error cannot be avoided, due to the

Ranking the Best Binary Trees

SIAM Journal on Computing, 1989
Summary: The problem of ranking the K-best binary trees with respect to their weighted average leaves' levels is considered. Both the alphabetic case, where the order of the weights in the sequence \(w_ 1,...,w_ n\) must be preserved in the leaves of the tree, and the nonalphabetic case, where no such restriction is imposed, are studied.

On Rotations and the Generation of Binary Trees

Journal of Algorithms, 1993
Summary: The rotation graph, \(G_ n\), has vertex set consisting of all binary trees with \(n\) nodes. Two vertices are connected by an edge if a single rotation will transform one tree into the other. We provide a simpler proof of a result of {\t J. M. Lucas} [J. Algorithms 8, 503-535 (1987; Zbl 0641.05015)] that \(G_ n\) contains a Hamilton path. Our

On the Average Shape of Binary Trees

SIAM Journal on Algebraic Discrete Methods, 1980
The average level numbers of the leaves of a binary tree are studied, where each binary tree is regarded as being equally likely. A formula is derived for the number of binary trees with jth leaf at a prescribed level. The asymptotic behavior of the average level number of the jth leaf is determined.

COMPUTABILITY IN UNCOUNTABLE BINARY TREES

The Journal of Symbolic Logic, 2019
Abstract Computability, while usually performed within the context of ω, may be extended to larger ordinals by means of α-recursion. In this article, we concentrate on the particular case of ω1-recursion, and study the differences in the behavior of ${\rm{\Pi }}_1^0$ -classes between this case and the standard one.
