The smart and cautious chess players are trying to figure it out and restrain each other, and everyone strives to win, making ma wonderful appearances. The greatness of game theory lies in the fact that it conducts a subtle analysis of human relationships and world through various quantitative concepts such as rules, identity, inmation, actions, utility, and balance, clearly reveals the various interactive behaviors and interactions of people in today's society, and provides guidance people to make correct decisions.
