大规模多项式Optimization中SDP松弛的正则化方法

Regularization Methods for SDP Relaxations in Large Scale Polynomial Optimization

Jiawang Nie, Li Wang

摘要:

研究了大规模多项式优化问题的半定规划松弛算法。当使用边界点法时,通常只能解决小问题或中等规模的问题。本文研究求解多项式最优化问题的正则化方法。我们描述了这些具有块结构的半定优化方法,并将其应用于求解大规模多项式最优化问题。各种数值例子的性能进行测试。通过正则化方法,可以在常规计算机上解决更大的问题,这几乎是不可能的内点方法。

英文摘要:

We study how to solve semidefinite programming relaxations for large scale polynomial optimization. When interior-point methods are used, typically only small or moderately large problems could be solved. This paper studies regularization methods for solving polynomial optimization problems. We describe these methods for semidefinite optimization with block structures, and then apply them to solve large scale polynomial optimization problems. The performance is tested on various numerical examples. By regularization methods, significantly bigger problems could be solved on a regular computer, which is almost impossible by interior point methods.
