摘要

在R/sup 3/中k个多面体的交点上，用它们的外部递归分解表示线性规划优化，在期望时间O(k log k log n+平方根k log k log/sup 3/ n)内完成了线性规划优化。这一结果用于导出动态线性规划问题的有效算法，这些问题需要插入和删除约束，查询必须优化指定的目标函数。作为应用，本文描述了平面二中心问题的一种改进解

Dynamic three-dimensional linear programming

Linear programming optimizations on the intersection of k polyhedra in R/sup 3/, represented by their outer recursive decompositions, are performed in expected time O(k log k log n+ square root k log k log/sup 3/ n). This result is used to derive efficient algorithms for dynamic linear programming problems ill which constraints are inserted and deleted, and queries must optimize specified objective functions. As an application, an improved solution to the planar 2-center problem, is described.<>
