Practical Manual of Multi-Subject Game Theory_ Understandable and Implementable for All, Analyzing Positive and Reserve Game Logic with Restaurants as the Core Case and Multi-Industry Extension

Associated Preprint DOI: 10.5281/zenodo.18339379 Abstract This working paper is a practical supplement to the preprint Human Beings Will Prevail, focusing on three original theories: Trait Locking Science, Prediction-Regulation Dual-Drive Game Theory (Positive Game), and Reserve Game. Taking home-cooked restaurants as the core case, it dissects the closed-loop logic of "positive prediction guidance + reserve feedback optimization" among multiple subjects and extends it to retail, workplace, and education scenarios. The paper abandons complex quantitative derivations, emphasizing accessibility and implementability—both academic researchers and the general public can grasp and apply the logic without profound professional knowledge. Its core value lies in verifying the universality and practicality of the three original theories, providing a actionable framework for multi-subject collaboration across industries.
