随着多目标最优化和半无限规划的研究发展,凸性理论逐步被广泛地应用到各个研究范畴中,且取得了许多有意义的重要成果。文献[1]引入了(F,α,ρ,d)-凸函数,文献[2]对其进一步推广,得到了(C,α,ρ,d)-凸函数,并研究了涉及这类凸性的最优性条件和对偶结果。文献[3-7]对于涉及(C,α,ρ,d)-凸性的多目标规划、多目标分式规划等问题的最优性和对偶理论进行了研究。作者在此基础上,结合局部渐近锥、K-方向导数[8]和K-次微分[9],提出广义(C,α,ρ,d)K,θ-凸函数,并在新的广义凸性下,研究了一类多目标半无限规划的最优性条件。
3 结语
本文定义了广义(C,α,ρ,d)K,θ-凸函数,讨论了涉及新广义凸性的一类多目标半无限规划的最优性条件,所得结果从理论上对已有凸性进行了有益推广,充实了广义凸性和数学规划的相关理论。还可进一步深入研究这类新广义凸性及其相关的对偶性、鞍点[14]和算法设计与稳定性分析等内容。
