"AN ANALYSIS OF THE COMPLEXITY OF THE SYSTEM EVERYTHING DEVELOPED FROM AND RAISED FROM HEAVEN AND EARTH IS IN ITS PROPER PLACE OF FORM MIND BOXING"
Xing Yi Quan (alternatively Hsing I Chuan—“Form Mind Boxing”) is a Chinese Internal Martial Art. Its origins are uncertain, but its lineage can be traced back more than a century. Xing Yi Quan is a system composed of five elements: Splitting Fist, Smashing Fist, Drilling Fist, Pounding Fist and Crossing Fist. The interrelations of the elements are formalized in the art in terms of Mutual Production (e.g. Splitting Fist generates Drilling Fist and is generated by Crossing Fist) and Mutual Conquest (e.g. Splitting Fist counters Smashing Fist and is countered by Pounding Fist.) The relations of generation by and countering by are completely stated by the systemic rules of behavior for each strike. The complete physical expression of the Five Fists is contained in the two person set An Shen Pao (“everything developed from and raised by heaven is in its proper place.”) This paper proposes to analyze An Shen Pao as a complex system emerging from the Five Fists. Because of the definitions of Mutual Production and Mutual Conquest fully define the interrelations of the component elements of the system those relations can be entirely measured. Similarly, the complexity of the set can be determined through examining each of the strikes of the two participants in terms of environment and action and charting the function of adaptation to the information received from the environment (opponent’s move.) As An Shen Pao is a closed and fully described system, a complete analysis of the complexity of this physical system can be done and an accurate conclusion as to its degree of complexity calculated.
