We analyze weighted depths of nodes with given labels, the last inserted node, nodes ordered as visited by the depth first search process, the weighted path length and the weighted Wiener index in a random binary search tree. We establish three regimes of nodes depending on whether the second...

p-order statistics a Gaussian limit law. Forp = 1 this gives the well-known result that the depth of a randomlyselected node in a random binary search tree converges in law to theNormal distribution.1. Introduction.in random search trees, respectively, random recursive trees were studied.It ...
random binary search tree under insertions and deletions under the conditions that (i) no extra permanent storage space be used besides the tree itself, and (ii) that at any point in time the tree be perfectly random, meaning that it is drawn from the ideal binary search tree distribution....
摘要: Let Hn be the height of a random binary search tree on n nodes. We show that there exist constants α = 4.311… and β = 1.953… such that E(Hn) = αln n − βln ln n + O(1), We also show that Var(Hn) = O(1).关键词:...
Limit laws for sums of functions of subtrees of random binary search trees We consider sums of functions of subtrees of a random binary search tree and obtain general laws of large numbers and central limit theorems. These sums co... L Devroye - 《Siam Journal on Computing》 被引量: 69...

However, unlike RFs, ERTs build each tree from the complete learning sample without bootstrap and for each of the split candidates a discretization threshold is selected at random to define a split, instead of choosing the best cut-point based on the local sample. View chapter Book series ...
A model is inferred by applying a decision tree learning algorithm on a test plan of unknown quality, and running it against a high quality test plan (in the case of [110], a test plan of high strength). The quality assessment is based on the probability of misclassification of the ...
