Our system, or any computer-simulation, is very small when compared to a chemical system. A small environment on earth contains an enormous amount of molecules. In a cup of water, for example there are about molecules. These can contain an amount of information we cannot hope to have in any computer simulation. It has to be determined whether Evolution exists only in such big systems.
Self replication is considered essential for Evolution.
This is the program which copies itself to various locations. The second behavior, the endless loop, could be considered as self replication when one looks at the time dimension. The behavior which evolved when there were many processors has no self-replication, it is some kind of growth. Another subject to be considered is the question of fitness. The fittest programs were those which managed to conquer most of the CPU time.
