Random binary tree, binary trees with various random distributions, including trees formed by random insertion orders, and trees that are uniformly distributed with a given number of nodes; Random recursive tree, increasingly labelled trees, which can be generated using a simple stochastic growth rule. Treap or randomized binary search tree, a ...
A random binary tree is a random tree drawn from a certain probability distribution on binary trees. In many cases, these probability distributions are defined using a given set of keys, and describe the probabilities of binary search trees having those keys.
A rapidly exploring random tree (RRT) is an algorithm designed to efficiently search nonconvex, high-dimensional spaces by randomly building a space-filling tree.The tree is constructed incrementally from samples drawn randomly from the search space and is inherently biased to grow towards large unsearched areas of the problem.
Random forests or random decision forests is an ensemble learning method for classification, regression and other tasks that works by creating a multitude of decision trees during training. For classification tasks, the output of the random forest is the class selected by most trees.
In a random recursive tree, all such trees are equally likely. Alternatively, a random recursive tree can be generated by starting from a single vertex, the root of the tree, labeled , and then for each successive label from to choosing a random vertex with a smaller label to be its parent. If each of the choices is uniform and independent of ...
A random tree is a tree or arborescence that is formed by a stochastic process. In a large range of random graphs of order n and size M ( n ) the distribution of the number of tree components of order k is asymptotically Poisson .
After any sequence of insertions and deletions of keys, the shape of the tree is a random variable with the same probability distribution as a random binary tree; in particular, with high probability its height is proportional to the logarithm of the number of keys, so that each search, insertion, or deletion operation takes logarithmic time to ...
In graph theory, a recursive tree (i.e., unordered tree) is a labeled, rooted tree. A size- n recursive tree's vertices are labeled by distinct positive integers 1, 2, …, n , where the labels are strictly increasing starting at the root labeled 1.
