Superimposing class 2-like transitions on an intermediate layer of class 3 automata results in class 4 behavior.  \n 1. Introduction  \nSince the conception of the idea of complex systems in the field of statistical mechanics, it has been expected that the notion of complexity can be reduced to a set of simple rules applicable at a microscopic scale. Cellular automata (CAs) revealing diverse complex behavior are also used as tools for understanding complexity generated by simple rules. Wolfram has classified all CAs with respect to their patterns of time development. Namely, class 1 as stable homogeneous patterns, class 2 as local periodic patterns, and class 3 as chaotic patterns. In this regard, class 4 is characterized by both a local periodic pattern and a chaotic pattern that can interact with each other. Class 4 is found at the critical area between classes 2 and 3 in a specific rule space [1, 2] . Turing machines can also be implemented by using a“glider” [3], which characterizes class 4 rules. A glider can be used asa device for logical gates, shifts, delays, and reflections [4, 5] . Whether simple or complex, behaviors can be reduced to transition rules, and even class 4 behavior is not an exception from this generalization.  \nClass 4 automata are considered to exhibit an essential feature of biological systems in that a system is divided into stably periodic parts which can interact with each other. Robust but dynamic biological systems in nature are assumed to be hierarchical [6, 7], while class 4 automata have no hierarchical structure. The notion of hierarchy can be rather problematic. Physicists regard hierarchy as consisting of a layer that has its own time constant (e.g., [8]) . Different layers cannot influence each other due to differences between them in terms of the order of the time constant, and therefore the hierarchy can be maintained in a stable structure. In this sense, if the boundary between lay  \nComplex Systems, 19 © 2010 Complex Systems Publications, Inc.  \n178 Y.-P. Gunji  \ners is explicitly defined, hierarchy is found not in function but in structure. On the other hand, if there is a strong interaction between layers, it can break the boundary between layers as well as the hierarchy itself. Hierarchy involving interactions between layers might be in logical conflict.  \nSpecifically, in examining a biochemical network or an immune system, functional hierarchy cannot be found in the interaction between the layers since the loss of the functional boundary allows the interaction. On the other hand, structural hierarchy is found to be robust. There is an explicit double meaning between structure and function in looking for hierarchy. Naturally, the question arises whether observers can freely move between the two meanings. As hierarchical systems are self-organizing systems, the boundary between layers has tobe perpetually broken and reconstructed in order to be maintained ina robust state. This self-organizing process concerns not only structure, but also function. As a result, the boundary between structure and function is ambiguous and vague, and therefore the boundary between layers is destined to be ambiguous and vague. The notion of hierarchy itself is self-referential and ambiguous, and these properties have been recently reflected in the term “heterarchy” [9] .  \nHere, we clarify the notion: (i) Heterarchy is a hierarchy consisting of different layers, and (ii) the boundary between different layers cannot be controlled. Thus, an observer observing a phenomenon at a focal level cannot determine the layer exerting the strongest influence on the foca","cbCailrvM4D3TY3F","https://ap.wps.com/l/cbCailrvM4D3TY3F","pdf",2404823,18,"English","# Introduction\n## Cellular automata classes and class 4 characterization\n## Hierarchy, heterarchy, and emergence\n## Observer-dependent boundaries in emergence","[{\"question\":\"What approach does the paper use to induce class 4 behavior?\",\"answer\":\"It uses lattice analysis based on rough set approximation and builds class 4 behavior by superimposing class 2-like transitions on an intermediate layer of class 3 automata.\"},{\"question\":\"How is class 4 characterized in relation to classes 2 and 3?\",\"answer\":\"Class 4 is associated with both local periodic patterns and chaotic patterns that can interact, appearing in the critical region between class 2 and class 3 in a specific rule space.\"},{\"question\":\"What is the paper’s definition of heterarchy and why does it matter?\",\"answer\":\"Heterarchy is defined as a hierarchy with different layers whose boundary cannot be controlled.
