I recommend the papers by Christoph Flamm and collaborators: https://arxiv.org/search/?searchtype=3Dauthor&query=3D%22Flamm%2C+Christoph= %22 I heard Flamm and Merkle talk at "Dynamics, Thermodynamics and Information Processing in Chemical Networks" in Luxembourg last year, and I wrote: > Merkle is speaking.
