论文摘要

给定带有$ k $顶点的凸多边形$ P $和多边形域$ q $由多边形障碍物组成,总尺寸$ n $在飞机上,我们研究了可以找到可以将$ p $的最大类似副本放入$ q $的优化问题。我们提高了解决问题的时间复杂性到$ O(k^2n^2λ_4(k)\ log {n})$。这是改善Chew and Kedem [SocG89,CGTA93]和Sharir和Sharir和Toledo [SOCG91,CGTA94]的进展。

Given a convex polygon $P$ with $k$ vertices and a polygonal domain $Q$ consisting of polygonal obstacles with total size $n$ in the plane, we study the optimization problem of finding a largest similar copy of $P$ that can be placed in $Q$ without intersecting the obstacles. We improve the time complexity for solving the problem to $O(k^2n^2λ_4(k)\log{n})$. This is progress of improving the previously best known results by Chew and Kedem [SoCG89, CGTA93] and Sharir and Toledo [SoCG91, CGTA94] on the problem in more than 25 years.
