Experiments with a Turing gas: Mimicking Chemical evolution.

ABSTRACT

Three different experiments with colliding artificial molecules, made of binary strings, are reported. Rules of evolution are designed such that the innovative collisions, i.e., those producing new species at the end of a reaction, become a negligible part of total number of collisions after a sufficiently large number of collisions have taken place. The distribution of species in the final mixture according to their bit size as well as the decay profile of the reactive and the innovative collisions are obtained. It is seen that the prescribed rules are sufficient to characterize a self-regulatory feature of the evolving system.
