Selected topic: Emergence as complexity drop


Emergence takes place in an observer’s ‘mind’. The observer needs not be a human.
It is characterized by a sudden complexity drop when considering a collective.
Emergence can be studied in human or artificial societies, where individual agents may be aware of patterns emerging at the collective level.

    Keywords: EMERGENCE
    This chapter provides a critical survey of emergence definitions both from a conceptual and formal standpoint. The notions of downward / backward causation and weak / strong emergence are specially discussed, for application to complex social system with cognitive agents. Particular attention is devoted to the formal definitions introduced by (Müller 2004) and (Bonabeau & Dessalles, 1997), which are operative in multi-agent frameworks and make sense from both cognitive and social point of view. A diagrammatic 4-Quadrant approach, allow us to understanding of complex phenomena along both interior/exterior and individual/collective dimension.

    Keywords: EMERGENCE
    The present paper provides a formal definition of emergence, operative in multi-agent framework designed by Agent Oriented Programming, and which makes sense from both a cognitive and an economics point of view.

  4. Bonabeau, E. & Dessalles, J.-L. (1997). Detection and emergence. Intellectica, 25 (2), 85-94.
    Keywords: EMERGENCE SIMPLICITY
    Two different conceptions of emergence are reconciled as two instances of the phenomenon of detection. In the process of comparing these two conceptions, we find that the notions of complexity and detection allow us to form a unified definition of emergence that clearly delineates the role of the observer.

    Keywords: EMERGENCE
    Emergence seems to be a central concept in Artificial Life, Cognitive Science, and many other related domains, but the meaning of which is not really agreed upon. In this paper, we critically review some major conceptions of emergence and give some examples of phenomena that are usually considered emergent.

    Keywords: EMERGENCE
    The lack of a unifying conceptual framework for representing, characterizing and dealing with emergence and emergent phenomena,led us to study the building of such a framework, based on the notions of levels of organization and of levels of detection. Information theory and concepts related to theories of complexity will help us understand the nature of emergent phenomena.
