Abstract

We present approximation algorithms for cutting out polygons with line cuts and ray cuts Our results answer a number of open problems and are either the first solutions or significantly improve over previously known solutions For the line cutting version, we prove a key property that leads to a simple, constant factor approximation algorithm For the ray cutting version, we prove it is possible to compute in almost linear time a cutting sequence that is an O(log2n)-factor approximation No algorithms were previously known for the ray cutting version.
切割多边形与线和射线
我们提出了用线切割和射线切割切割多边形的近似算法。我们的结果回答了许多开放的问题,要么是第一个解决方案,要么是对先前已知的解决方案的显著改进。对于线切割版本,我们证明了一个关键性质,它导致了一个简单的,常数因子近似算法对于射线切割版本。我们证明了在几乎线性时间内计算一个O(log2n)因子近似的切割序列是可能的。射线切割版本之前没有已知的算法。
