Abstract Consideration ,ofthe structure of the Penrose pattem has led to speculation that a system with a Penrose tiling gro,md state might be subject to inherent glassy behavior. Monte Carlo simulauons show, using a simple model of the energetics, that there is no inherent glassiness in the Penrose tiling. Thermodynamic quantities measured are completely reversible, displaying no observable hysteresis, and the system may be easily cooled from a highly disordered configuration into its lowest energy state.
