Global rigidity of random graphs in $\mathbb{R}$
Abstract
We investigate the problem of reconstructing a set of distinct points, where the only information available about consists of the distances between some of the pairs of points. More precisely, we examine which properties of the graph of known distances, defined on the vertex set , ensure that can be uniquely reconstructed up to isometry. We prove that as soon as the random graph process has minimum degree 2, with high probability it can reconstruct all distances within any point set in . This resolves a conjecture of Benjamini and Tzalik. We also study the feasibility and limitations of reconstructing the distances within almost all points using much sparser random graphs. In doing so, we resolve a question posed by Gir\~ao, Illingworth, Michel, Powierski, and Scott.
