给出了一类非线性半定规划问题有效解的一种新方法和算法。新方法扩展了最近提出的概念,凸半定规划的解决方案的基础上的顺序凸规划(SCP)的想法。在该方法的核心,一个一般的非凸半定规划被一系列的子问题所取代,其中非线性约束和目标函数定义在矩阵变量近似块可分离的凸模型。在合理的假设下证明了算法的全局收敛性。本文的结论是具有挑战性的自由材料优化问题的位移约束的数值实验。
A new method and algorithm for the efficient solution of a class of nonlinear semidefinite programming problems is introduced. The new method extends a concept proposed recently for the solution of convex semidefinite programs based on the sequential convex programming (SCP) idea. In the core of the method, a generally non-convex semidefinite program is replaced by a sequence of subproblems, in which nonlinear constraint and objective functions defined in matrix variables are approximated by block separable convex models. Global convergence is proved under reasonable assumptions. The article is concluded by numerical experiments with challenging Free Material Optimization problems subject to displacement constraints.
