網頁2024年6月27日 · Several equivalent conditions for the Steiner–Gromov ratio of a metric space to be equal to one are stated, i.e., conditions for each minimal spanning tree in any finite subset of a given metric space to be both a shortest tree and a minimal filling. A complete classification of such spaces is obtained.

Steiner Minimal Trees

網頁Abstract. Let P be a set of n points on the euclidean plane. Let L s ( P) and L m ( P) denote the lengths of the Steiner minimum tree and the minimum spanning tree on P, respectively. In 1968, Gilbert and Pollak conjectured that for any P, L s ( P )≥ (√3/2) L m ( P ). We provide a proof for their conjecture in this paper. 網頁Ratio theorem 網頁2024年3月24日 · Steiner's Theorem.
