平面图中的边界到边界流
Boundary-to-boundary flows in planar graphs
摘要:
本文给出了一个求平面图边界上一组源和汇之间最大流的迭代算法。我们的算法只使用O(n)查询简单的数据结构,实现了O(n log n)的运行时间,我们希望是实际的简单原语的使用。这个问题的唯一现有算法使用分治,为了实现O(n log n)的运行时间,需要使用(复杂的)线性时间最短路径算法的平面图。
英文摘要:
We give an iterative algorithm for finding the maximum flow between a set of sources and sinks that lie on the boundary of a planar graph. Our algorithm uses only O(n) queries to simple data structures, achieving an O(n log n) running time that we expect to be practical given the use of simple primitives. The only existing algorithm for this problem uses divide and conquer and, in order to achieve an O(n log n) running time, requires the use of the (complicated) linear-time shortest-paths algorithm for planar graphs.
