ARTIFICIAL MICRO WORLDS. PART IV: MODELS OF COMPLEX SELF-REPRODUCERS

As Wolfram classification of cellular automata, we have divided a taxonomy of Artificial Micro Worlds (AMWs) into four classes. In previous work, we have presented many examples of self-reproducers belonging to Class 1. In this paper, we present a series of AMWs, belonging to Class 2 (complex AMWs which contain complex species of self-reproducers); Class 3 (which contains species of self-reproducers with chaotic behavior) and Class 4 (which contains species with hyper complex self-reproducers). In particular, we introduce an AMW, belonging to Class 2 (a loop-shaped system); several AMWs, belonging to Class 3 (species with a linear and chaotic behavior) and a series of AMWs, belonging to Class 4 (with species which show very different behaviors). Particular attention will be dedicated to a new type of AMW, which contains a species that has an incorporated developmental program.
