Query: Chemlambda, universality and self-multiplication   We present chemlambda (or the chemical concrete machine), an artificial
chemistry with the following properties: (a) is Turing complete, (b) has a
model of decentralized, distributed computing associated to it, (c) works at
the level of individual (artificial) molecules, subject of reversible, but
otherwise deterministic interactions with a small number of enzymes, (d)
encodes information in the geometrical structure of the molecules and not in
their numbers, (e) all interactions are purely local in space and time. This is
part of a larger project to create computing, artificial chemistry and
artificial life in a distributed context, using topological and graphical
languages.
