In this paper, it was shown that the length of the shortest closed path through n points in a bounded plane region of area v is almost always asymptotically proportional to √(nv) for large n; and this result was extended to bounded Lebesgue sets in k-dimensional Euclidean space.
Abstract
We prove that the length of the shortest closed path through n points in a bounded plane region of area v is ‘almost always’ asymptotically proportional to √(nv) for large n; and we extend this result to bounded Lebesgue sets in k–dimensional Euclidean space. The constants of proportionality depend only upon the dimensionality of the space, and are independent of the shape of the region. We give numerical bounds for these constants for various values of k; and we estimate the constant in the particular case k = 2. The results are relevant to the travelling-salesman problem, Steiner's street network problem, and the Loberman—Weinberger wiring problem. They have possible generalizations in the direction of Plateau's problem and Douglas' problem.

Rates of Convergence of Means for Distance-Minimizing Subadditive Euclidean Functionals

TL;DR: In this paper, it was shown that a uniform i.i.d. sample from [0, 1]d converges to a finite constant for a class of graphs with vertex set equal to, or in some cases containing, minimal spanning trees.

Bounds and Approximations for the Transportation Problem of Linear Programming and Other Scalable Network Problems

TL;DR: It is found that if the cost functions have economies of scale, then the cost per item is bounded in 2-D, which explains the prevalence of the "last mile" effect in many logistics applications.

Direct estimation of information divergence using nearest neighbor ratios

TL;DR: In this article, a graph theoretical interpretation was proposed to estimate Renyi and f-divergence measures based on a new graph theory interpretation and showed that the average powered ratio of the number of X points to the number Y points among all k-NN points is proportional to Renyi divergence of X and Y densities.
