全局最优理论和方法，由于全局性的要求，比局部最优理论和方法更为困难，特别是，至今还没有很好的全局最优性的判别准则，故多数算法法缺少好的终止准则.西文提出了一个只需计算函数值的离散均值—水平集求全局最优的方法，给出了算法的终止准则，证明了算法的收敛性，并给出了某些数值例子.

The theory and method of global minimization is more difficult than local minimization. Especially up to now, there is no optimal criterion for global optimization, so there is lack of good termination rule.In this paper, we propose an algorithm for finding global minimization by discrete mean value-level set, the convergence of this algorithm is proved, a termination rule and some numerical examples are given.
