ABSTRACT
Complexity is a quality of a formal model or live system characterised by a very large number of interconnected and interdependent parts and multiple levels of embeddedness and entanglement. The complexity view of nature and human society was derived from mathematics. In contrast, complexity jargon uses the term 'repeller' to symbolize influences and/or states of a system that threaten the wholeness and organization of a complex system. Self-organization is reflected in many sources as an adaptation by complex systems. Lebed and Bar-Eli interpret proactiveness as a complementary quality of complex systems standing in contradistinction to reactiveness. This quality of complex systems is mainly interpreted as emergent behaviour with a powerful vector running from chaos to order. PMDS has a crucially important role in game playing. This analysis has highlighted the central role of the successful adaptation of human complex systems in sport contests and business competition.
