n 人非合作博弈 纳什均衡 基于文章"An Optimization Formulation to Compute Nash Equilibrium in finite Games"的源码-The function npg solves an n-person finite non-co-operative game to

compute one sample Nash Equilibrium. It uses an optimization formulation

of n-person non-co-operative games as described in the adjoining paper

"An Optimization Formulation to Compute Nash Equilibrium in finite

Games"
