In this paper, we design a self-stabilizing algorithm which finds a 2-center for a distributed system with a tree topology. Our algorithm is based on the algorithm in [1][2][3]. The latter enables us to find the center (or centers) for the tree. If we sever the tree at the center (or centers), we ob
The closest tree algorithΒ’a for estimating the evolutionary history of n species, from a set of homologous DNA or RNA sequences is designed to avoid the problem of inconsistency inherent in current methods. The algorithm, as previously described, required O(n~2 n) steps, making it impractical for va
Given a tree containing n vertices, consider the sum of the distance between all Ε½ . vertices and a k-leaf subtree subtree which contains exactly k leaves . A k-tree core is a k-leaf subtree which minimizes the sum of the distances. In this paper, we propose a linear time algorithm for finding a k-t
