Mincheol Kim, Hee-Kap Ahn

Consider two axis-aligned rectilinear simple polygons in the domain consisting of axis-aligned rectilinear obstacles in the plane such that the bounding boxes, one for each obstacle and one for each polygon, are disjoint. We present an algorithm that computes a minimum-link rectilinear shortest path connecting the two polygons in $O((N+n)\log (N+n))$ time using $O(N+n)$ space, where $n$ is the number of vertices in the domain and $N$ is the total number of vertices of the two polygons.

直线障碍中多边形的最小链接最短路径

考虑在由平面中的轴对齐的直线障碍物组成的域中的两个轴对齐的直线简单多边形,使得边界框,每个障碍物一个,每个多边形一个,是不相交的。我们提出了一种算法,该算法使用 $O(N+n)$ 空间计算在 $O((N+n)\log (N+n))$ 时间内连接两个多边形的最小链接直线最短路径,其中 $n $ 是域中的顶点数,$N$ 是两个多边形的顶点总数。
