**摘要** 在文献中,很少有研究对邻近点算法(PPA)中的一些参数进行设计,特别是对于多目标凸优化而言。在PPA中引入一些参数可使其更灵活且更具吸引力。M(最后这个“M”不太清楚在原语境中的准确含义,如果还有更多相关内容,请提供完整信息以便更好地翻译)
ABSTRACT In the literature, there are a few researches to design some parameters in the proximal point algorithm (PPA), especially for the multi-objective convex optimizations. Introducing some parameters to PPA can make it more flexible and attractive. Mainly motivated by our recent work [Bai et al. A parameterized proximal point algorithm for separable convex optimization. Optim Lett. (2017) doi:10.1007/s11590-017-1195-9], in this paper we develop a general parameterized PPA with a relaxation step for solving the multi-block separable structured convex programming. By making use of the variational inequality and some mathematical identities, the global convergence and the worst-case convergence rate of the proposed algorithm are established. Preliminary numerical experiments on solving a sparse matrix minimization problem from statistical learning validate that our algorithm is more efficient than several state-of-the-art algorithms.
