摘要:
我们考虑牛顿方法用于常见的单商品和多商品网络流问题。尽管问题的维度可能非常大,但如近三十年来所展示的,可以使用共轭梯度法和低维网络操作来实现。我们重新审视这些方法,比较它们与更近期的提案,并描述如何在分布式计算系统中实现。我们还讨论了扩展问题,包括弧收益的处理、线性侧约束及相关特殊结构。
英文摘要:
We consider Newton methods for common types of single commodity and multi-commodity network flow problems. Despite the potentially very large dimension of the problem, they can be implemented using the conjugate gradient method and low-dimensional network operations, as shown nearly thirty years ago. We revisit these methods, compare them to more recent proposals, and describe how they can be implemented in a distributed computing system. We also discuss generalizations, including the treatment of arc gains, linear side constraints, and related special structures.
