A SMOOTHING APPROXIMATION TO THE EXACT PENALTY FUNCTION FOR OPTIMIZATION WITH INEQULITY CONSTRAINTS
不等式约束最优化的非光滑精确罚函数的一个光滑近似

In this paper, a approximate exact differential penalty function for optimization with inequality constraint is introduced and its properties are studied. As a result, two new penalty methods are proposed and the global convergence of the two methods is obtained.
