WebIn 1964, Böröczky [13] constructed two-dimensional disk packings that are sparse, that is, have vanishing density in the limitN→∞. The properties of these Böröczky packings are very different from those of the densest hexagonal lattice. Infinitesimal motion of just a single disk remains impossible, so that Böröczky packings are locally stable. WebWe propose locally stable sparse hard-disk packings, as introduced by Böröczky, as a model for the analysis and benchmarking of Markov-chain Monte Carlo (MCMC) algorithms. We create women
