摘要:

多面体投影算子在现代优化中发挥着基础且重要的作用。近年来,多面体投影算子的广义雅可比的计算研究取得了重要进展。本文回顾了一些关于多面体投影和它们的广义雅可比的理论和计算发展。类似的分析也扩展到了强凸二次规划问题的解映射和连续分段仿射正则化函数的邻近映射。

关键词: 多面体投影, 广义雅可比, 非光滑分析

Abstract:

Polyhedral projectors play a fundamental role in modern optimization. Recently, significant progress has been made in the computation of generalized Jacobians of projectors over polyhedral convex sets. In this paper, we review some recent theoretical and computational developments related to polyhedral projectors and their generalized Jacobians. Similar analyses are also extended to solution mappings of strongly convex quadratic programming problems, and proximal mappings of continuous piecewise affine regularizers.

Key words: projection onto polyhedrons, generalized Jacobians, nonsmooth analysis
