无约束几何规划和尺度问题的内点法

Interior-point methods for unconstrained geometric programming and scaling problems

Peter Bürgisser, Yinan Li, Harold Nieuwboer, Michael Walter

摘要:

我们提供了一个基于条件的分析两个内点点的方法无约束几何规划,一类凸规划,自然出现在应用程序,包括矩阵缩放,矩阵平衡,熵最大化。我们的条件数是与几何规划的牛顿多面体相关联的自然几何量,并导致近似极小值的直径界。我们还提供了有效的界限上的条件数在一般情况下和组合假设下的牛顿多面体。通过这种方式,我们推广了最近的内点方法的矩阵缩放和矩阵平衡的迭代复杂性。最近,有很多关于李群上某些最优化问题的算法的工作,称为容量和缩放问题。对于交换群,这些问题减少到无约束的几何规划,这是我们工作的一个特别的动力来源。

英文摘要:

We provide a condition-based analysis of two interior-point methods for unconstrained geometric programs, a class of convex programs that arise naturally in applications including matrix scaling, matrix balancing, and entropy maximization. Our condition numbers are natural geometric quantities associated with the Newton polytope of the geometric program, and lead to diameter bounds on approximate minimizers. We also provide effective bounds on the condition numbers both in general and under combinatorial assumptions on the Newton polytope. In this way, we generalize the iteration complexity of recent interior-point methods for matrix scaling and matrix balancing. Recently, there has been much work on algorithms for certain optimization problems on Lie groups, known as capacity and scaling problems. For commutative groups, these problems reduce to unconstrained geometric programs, which serves as a particular source of motivation for our work.
