摘要:

我们研究如何求解光滑矩阵优化问题,其中对称矩阵的特征值受到一般线性不等式约束。我们提出了求解方法,以获取线性目标函数(即 $F(X) = \langle C, X \rangle$)的精确全局最小值,并在特征值约束集上执行精确投影。我们开发了两种一阶算法,用于获取一般非凸目标函数的一阶稳定点。当约束集为凸时,两种方法均被证明具有次线性收敛性。数值实验证明了模型和方法的适用性。

英文摘要:

We investigate how to solve smooth matrix optimization problems with general linear inequality constraints on the eigenvalues of a symmetric matrix. We present solution methods to obtain exact global minima for linear objective functions, i.e., $F(X) = \langle C, X \rangle$, and perform exact projections onto the eigenvalue constraint set. Two first-order algorithms are developed to obtain first-order stationary points for general non-convex objective functions. Both methods are proven to converge sublinearly when the constraint set is convex. Numerical experiments demonstrate the applicability of both the model and the methods.
