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 selectedRandom minimal spanning tree, spanning trees of a graph formed by choosing random edge weights and using the minimum spanning tree for those weightsRandom 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 randomRandom 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 simulate a random binary tree for non-random update sequencesRapidly exploring random tree, a fractal space-filling pattern used as a data structure for searching high-dimensional spacesBrownian tree, a fractal tree structure created by diffusion-limited aggregation processesRandom 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 classificationBranching process, a model of a population in which each individual has a random number of children
