Branches in random recursive k-ary trees
In this paper, using generalized {polya} urn models we find the expected value of the size of a branch in recursive $k$-ary trees. We also find the expectation of the number of nodes of a given outdegree in a branch of such trees.
متن کاملAn Improved Succinct Representation for Dynamic k-ary Trees
k-ary trees are a fundamental data structure in many textprocessing algorithms (e.g., text searching). The traditional pointer-based representation of trees is space consuming, and hence only relatively small trees can be kept in main memory. Nowadays, however, many applications need to store a huge amount of information. In this paper we present a succinct representation for dynamic k-ary tree...
متن کاملOn generating k-ary trees in computer representation
Many algorithms have been developed to generate sequences for trees, and a few are to generate trees themselves, i.e., in computer representation. Two new algorithms are presented in this paper to generate k-ary trees in computer representation. One is recursive with constant average time per tree and the other is loopless (non-recursive) with constant time per tree. Both of them are simple and...

متن کاملOn k-ary spanning trees of tournaments
It is well known that every tournament contains a Hamiltonian path, which can be restated as that every tournament contains a unary spanning tree. The purpose of this article is to study the general problem of whether a tournament contains a k-ary spanning tree. In particular, we prove that, for any fixed positive integer k, there exists a minimum number h(k) such that every tournament of order...
