只有heuristic的算法吧,和R* tree很相像。
https://en.wikipedia.org/wiki/R-tree
R* tree topological split.[13]
The pages overlap much less since the R*-tree tries to minimize page overlap, and the reinsertions further optimized the tree. The split strategy prefers quadratic pages, which yields better performance for common map applications.
【 在 garland 的大作中提到: 】
: 研究中遇到一个算法问题,描述如下:
: 二维空间中分布M个点,求N个矩形(其中N是人为设定的数),使得:(1)这N个矩形覆盖所有M个点;(2)这N个矩形面积之和最小。
: 不知这样的问题是否有非暴力算法给出最优解?如果没有,能否有算法给出近似解?
