Random ultrametric trees and applications*
ESAIM: Proceedings and Surveys, 2017 Ultrametric trees are trees whose leaves lie at the same distance from the root. They are used to model the genealogy of a population of particles co-existing at the same point in time.

Simply generated trees, conditioned Galton―Watson trees, random allocations and condensation: Extended abstract [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We give a unified treatment of the limit, as the size tends to infinity, of random simply generated trees, including both the well-known result in the standard case of critical Galton-Watson trees and similar but less well-known results in the other ...

Expected size of a tree in the fixed point forest [PDF]
Discrete Mathematics & Theoretical Computer Science, 2019 We study the local limit of the fixed-point forest, a tree structure associated to a simple sorting algorithm on permutations. This local limit can be viewed as an infinite random tree that can be constructed from a Poisson point process configuration on

Selection of Random Minimum Spanning Tree Based on Intuitionistic Fuzzy Sets [PDF]
Jisuanji gongcheng, 2016 To solve the difficulty of selecting nodes for network topology in complex environment,a selection method of random minimum spanning tree based on intuitionistic fuzzy sets is proposed.Through analyzing the uncertainty,like randomness and fuzziness ...

A new generation tree for permutations, preserving the number of fixed points [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 We describe a new uniform generation tree for permutations with the specific property that, for most permutations, all of their descendants in the generation tree have the same number of fixed points.

Improved Bidirectional RRT* Algorithm for Robot Path Planning
Sensors, 2023 In order to address the shortcomings of the traditional bidirectional RRT* algorithm, such as its high degree of randomness, low search efficiency, and the many inflection points in the planned path, we institute improvements in the following directions.
