In a randomly grown binary search tree BST of size n, any fixed pattern occurs with a frequency that is on average proportional to n. Deviations from the average case are highly unlikely and well quantified by a Gaussian law. Trees with forbidden patterns occur with an exponentially small probabilit

β¦ Synopsis
Mapping patterns may be represented by unlabelled directed graphs in which each point has outdegree one. We consider the uniform probability measure on the set of all mapping patterns on (n) points and derive the limiting distribution of the size of the largest tree as (n \rightarrow \infty). It is also shown that the asymptotic results concerning the structure of trees of a random mapping pattern coincide with those obtained earlier for the graphs of mappings on labelled point-sets.

## Abstract Using generating functions and asymptotic techniques, the probability that in a large random tree a point is of degree __r__ and an orbit of size __s__ for __r__ β€ 7 and __s__ β€ 7 is calculated. For example, it is found that about 17% of the points of a random tree are fixed and have de
## Abstract Motivated by the observation that the sparse treeβlike subgraphs in a small world graph have large diameter, we analyze random spanning trees in a given host graph. We show that the diameter of a random spanning tree of a given host graph __G__ is between and with high probability., w
