Random tree

En théorie des probabilités un arbre aléatoire est un arbre défini en utilisant une loi de probabilité sur un ensemble d'arbres (au sens de graphe). Par exemple, un arbre aléatoire à n nœuds peut être choisi aléatoirement parmi tous les arbres à n nœuds suivant une loi de probabilité, par exemple avec une loi uniforme. Il existe d'autres manières de générer certains arbres particuliers (binaires par exemple). Les arbres de Galton-Watson sont des cas particuliers d'arbres aléatoires.

在電腦科學和數學裡面,一個隨機樹是一個經由隨機過程建立的樹或者樹狀圖(arborescence)。 隨機樹有以下幾種類別:
* (Uniform spanning tree)
* 隨機最小生成樹(random minimal spanning tree)
*
* (Random recursive tree)
* Treap或者說隨機二元搜尋樹
* (Rapidly-exploring random tree)
* (brownian tree)
* 隨機森林

In mathematics and computer science, a random tree is a tree or arborescence that is formed by a stochastic process. Types of random trees include:
* Uniform spanning tree, a spanning tree of a given graph in which each different tree is equally likely to be selected
* Random minimal spanning tree, spanning trees of a graph formed by choosing random edge weights and using the minimum spanning tree for those weights
* Random binary tree, binary trees with a given number of nodes, formed by inserting the nodes in a random order or by selecting all possible trees uniformly at random
* Random recursive tree, increasingly labelled trees, which can be generated using a simple stochastic growth rule.
* Treap or randomized binary search tree, a data structure that uses random choices to simul

* Rapidly exploring random tree, a fractal space-filling pattern used as a data structure for searching high-dimensional spaces
* Brownian tree, a fractal tree structure created by diffusion-limited aggregation processes
* Random forest, a machine-learning classifier based on choosing random subsets of variables for each tree and using the most frequent tree output as the overall classification
* Branching process, a model of a population in which each individual has a random number of children
