摘要
Chung and Graham conjectured (in 1981) that n points in the unit square [0,1](2) can be connected by a rectilinear Steiner tree of length at most root n + 1. Here we confirm this conjecture for small values of n, and for some new infinite sequences of values of n (but not for all n). As an interesting byproduct we obtain close rational approximations of root n from below, for those n. (C) 2017 Elsevier B.V. All rights reserved.
