Self-evolution in a constructive binary string system

We examine the qualitative dynamics of a catalytic self-organizing system o f binary strings that is inspired by the chemical information processing me taphor. A string is interpreted in two different ways: either (a) as raw da ta or (b) as a machine that is able to process another string as data in or der to produce a third one. This article focuses on the phenomena of evolut ion whose appearance is notable because no explicit mutation, recombination , or artificial selection operators are introduced. We call the system self -evolving because every variation is performed by the objects themselves in their machine form.
