[FRIAM] Universal and Accessible Entropy Estimation Using a Compression Algorithm

[Roger Critchlow]

What is the relationship between physical entropy and information?

Well, according to this,
https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.123.178102, also
available as a preprint, https://arxiv.org/pdf/1709.10164.pdf, and the
press release from Tel Aviv University turning up here and there, you can
compute an accurate estimate of the physical entropy of a molecular
dynamics simulation by running zip compression on the coordinate
trajectories of the simulation and looking at the compression achieved.

This makes perfect sense and it's amazing it took us this long to figure it
out.
