  The 2016 Snook Prize has been awarded to Diego Tapias, Alessandro Bravetti,
and David Sanders for their paper -- Ergodicity of One-Dimensional Systems
Coupled to the Logistic Thermostat. They introduced a relatively stiff
hyperbolic tangent thermostat force and successfully tested its ability to
reproduce Gibbs' canonical distribution for the harmonic oscillator, the
quartic oscillator, and the Mexican Hat potentials. Their work constitutes an
effective response to the 2016 Ian Snook Prize Award goal -- Finding ergodic
algorithms for Gibbs' canonical ensemble using a single thermostat variable. We
confirm their work here and highlight an interesting feature of the Mexican Hat
problem when it is solved with an adaptive integrator.
