摘要:

我们研究约束多项式优化问题(POPs)的T-半定规划(SDP)松弛方法。无约束POP的T-SDP松弛由Zheng、Huang与Hu于2022年提出。本研究针对带多项式不等式约束的POP提出一种T-SDP松弛,并证明该用三阶张量构建的T-SDP松弛可转化为具有块对角结构的标准SDP松弛。在适度假设下,随着松弛阶数提升,T-SDP松弛的解收敛于给定约束POP的最优值。此外,我们还讨论了该T-SDP松弛的可行性与最优性。数值结果表明,所提T-SDP松弛提升了数值效率。

英文摘要:

We study T-semidefinite programming (SDP) relaxation for constrained polynomial optimization problems (POPs). T-SDP relaxation for unconstrained POPs was introduced by Zheng, Huang and Hu in 2022. In this work, we propose a T-SDP relaxation for POPs with polynomial inequality constraints and show that the resulting T-SDP relaxation formulated with third-order tensors can be transformed into the standard SDP relaxation with block-diagonal structures. The convergence of the T-SDP relaxation to the optimal value of a given constrained POP is established under moderate assumptions as the relaxation level increases. Additionally, the feasibility and optimality of the T-SDP relaxation are discussed. Numerical results illustrate that the proposed T-SDP relaxation enhances numerical efficiency.
