Necessary optimality conditions for a bilevel optimization problem are given in the paper by Kohli (J Optim Theory Appl 152: 632–651, 2012). Recently, the same author corrected his results in the note (J Optim Theory Appl 181:706–707, 2019). In this work, we have pointed out that some of the new modifications are wrong. We correct the flaws and present an alternative proof for the main result.

评论“关于“使用凸面因子的乐观双层规划问题的最优条件”一文的注释”

Kohli 的论文 (J Optim Theory Appl 152: 632–651, 2012) 中给出了双层优化问题的必要最优性条件。最近，同一作者在注释中更正了他的结果（J Optim Theory Appl 181:706-707, 2019）。在这项工作中，我们已经指出了一些新的修改是错误的。我们纠正了缺陷并为主要结果提供了替代证明。
