最大熵采样的混合凸优化界

Mixing convex-optimization bounds for maximum-entropy sampling

Zhongzhu Chen, Marcia Fampa, Amélie Lambert, Jon Lee

摘要:

最大熵抽样问题是空间统计学中一个基本的、具有挑战性的组合最优化问题。它要求找到一个最大行列式阶$s$主子矩阵的顺序-$n$协方差阵。这个NP难问题的精确解方法是基于一个分支定界框架。许多已知的最优值的上界是基于凸优化的。我们提出了一种方法来“混合”这些界限,以实现更好的界限。

英文摘要:

The maximum-entropy sampling problem is a fundamental and challenging combinatorial-optimization problem, with application in spatial statistics. It asks to find a maximum-determinant order-$s$ principal submatrix of an order-$n$ covariance matrix. Exact solution methods for this NP-hard problem are based on a branch-and-bound framework. Many of the known upper bounds for the optimal value are based on convex optimization. We present a methodology for "mixing" these bounds to achieve better bounds.
