Given a tree containing n vertices, consider the sum of the distance between all ลฝ . 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

A core of a tree \(T=(V, E)\) is a path in \(T\) which minimizes \(\Sigma_{v \in V}\) \(d(v, P)\), where \(d(v, P)\), the distance from a vertex \(v\) to path \(P\), is defined as \(\min _{u \in P} d(v, u)\). We present an optimal parallel algorithm to find a core of \(T\) in \(O(\log n)\) time usin

We first give a one-pass algorithm for finding the core of a tree. This algorithm is a refinement of the two-pass algorithm of Morgan and Slater. We then define a generalization of a core which we call a \(k\)-tree core. Given a tree \(T\) and parameter \(k\), a \(k\)-tree core is a subtree \(T^{\pr

A core of a graph G is a path P in G that is central with respect to the property to path P. This paper presents efficient algorithms for finding a core of a tree with ลฝ . a specified length. The sequential algorithm runs in O n log n time, where n is the ลฝ 2 . ลฝ. size of the tree. The parallel alg

In this paper, we propose efficient parallel algorithms on the EREW PRAM for optimally locating in a tree network a path-shaped facility and a tree-shaped facility of a specified length. Edges in the tree network have arbitrary positive lengths. Two optimization criteria are considered: minimum ecce
