给定平面上的k个端点和n个轴平行的矩形障碍物,我们的算法找到一个平面区域R*,使得对于R*中的任意点p,连接p和k个端点且不经过任何障碍物的最短直线路径的总长度最小。该算法对输出敏感,如果K是一个固定常数,则需要O((K+n) log n)时间和O(K+n)空间,其中K是找到的区域R*的多边形顶点的总数。
Given k terminals and n axis-parallel rectangular obstacles on the plane, our algorithm finds a plane region R* such that, for any point p in R*, the total length of the k shortest rectilinear paths connecting p and the k terminals without passing through any obstacle is minimum. The algorithm is output-sensitive, and takes O((K+n) log n) time and O(K+n) space if k is a fixed constant, where K is the total number of polygonal vertices of the found region R*.
