Based on the equilibrium theory of game theory and calculation methods, this book proposes to enrich and improve the existing Nash equilibrium refining methods. On the basis of constructing continuous equilibrium mapping, the simple path tracking approach refining Nash equilibrium point method for calculating perfect equilibrium point, appropriate equilibrium point, and a perfect d-proper equilibrium point is established respectively, and this method is applied to some famous game models to calculate equilibrium points and demonstrate its effectiveness.
