摘要:

论文研究了一种双层规划的光滑化目标罚函数算法,在一些条件下,证明了光滑化罚优化问题等价于原双层规划问题,而且,当下层规划问题是凸规划问题时,
给出了一个求解算法和收敛性证明.

Abstract:

In this paper, a novel smoothing objective penalty function is introduced for bilevel programming problems. It is proved that an optimal solution to the smoothing objective penalty optimization problem is also an optimal solution to the riginal bilevel programming problem under some mild conditions. Furthermore, for the bilevel programming problems with convexity to the lower level problem, an algorithm based on the proposed method is introduced, its convergence is proved.
