Recursive construction of continuum random trees [PDF]

open access: yesAnnals of Probability, 2016
We introduce a general recursive method to construct continuum random trees (CRTs) from independent copies of a random string of beads, that is, any random interval equipped with a random discrete probability measure, and from related structures.

Tail Bounds for the Wiener Index of Random Trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Upper and lower bounds for the tail probabilities of the Wiener index of random binary search trees are given. For upper bounds the moment generating function of the vector of Wiener index and internal path length is estimated.

Limits of random trees [PDF]

open access: yesActa Mathematica Hungarica, 2013
Local convergence of bounded degree graphs was introduced by Benjamini and Schramm. This result was extended further by Lyons to bounded average degree graphs. In this paper, we study the convergence of a random tree sequence where the probability of a given tree is proportional to $\prod_{v_i\in V(T)}d(v_i)!$.

The height of random binary unlabelled trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
This extended abstract is dedicated to the analysis of the height of non-plane unlabelled rooted binary trees. The height of such a tree chosen uniformly among those of size $n$ is proved to have a limiting theta distribution, both in a central and local

The scaling of the minimum sum of edge lengths in uniformly random trees [PDF]

open access: yesarXiv.org, 2016
The minimum linear arrangement problem on a network consists of finding the minimum sum of edge lengths that can be achieved when the vertices are arranged linearly.

Random Recursive Trees and Preferential Attachment Trees are Random Split Trees [PDF]

open access: yesCombinatorics, Probability and Computing, 2018
We consider linear preferential attachment trees, and show that they can be regarded as random split trees in the sense of Devroye (1999), although with infinite potential branching. In particular, this applies to the random recursive tree and the standard preferential attachment tree.

Election algorithms with random delays in trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
The election is a classical problem in distributed algorithmic. It aims to design and to analyze a distributed algorithm choosing a node in a graph, here, in a tree. In this paper, a class of randomized algorithms for the election is studied.

On the Zagreb index of random m-oriented recursive trees [PDF]

open access: yesTransactions on Combinatorics, 2023
The main goal of this paper is to study the modified $F$-indices (modified first Zagreb index and modified forgotten topological index) of random $m$-oriented recursive trees (RMORTs).

Spectral atoms of unimodular random trees [PDF]

open access: yesJournal of the European Mathematical Society (Print), 2016
We use the Mass Transport Principle to analyze the local recursion governing the resolvent $(A-z)^{-1}$ of the adjacency operator of unimodular random trees.

Extremely randomized trees [PDF]

open access: yesMachine Learning, 2006
This paper proposes a new tree-based ensemble method for supervised classification and regression problems. It essentially consists of randomizing strongly both attribute and cut-point choice while splitting a tree node. In the extreme case, it builds totally randomized trees whose structures are independent of the output values of the learning sample.
