Research output: Contribution to journalArticlepeer-review

Abstract

Three algorithms are given to construct a weighted r-ary tree with a given set of integer weighted leaves in which the weight of a parent node is 1 + max of its sons. Two goals are of interest; to minimize 1) the weight of the root of the tree, and 2) the number of internal nodes. Formulas for the optimum values of 1) and 2) are presented. We show that the first algorithm simultaneously optimizes both 1) and 2), the second only 2) while nearly optimizing 1), and the third op-
