考虑寻找简单多边形 P 中通过其边界上的点 s 的最短看守路线的问题。如果一条路线是一条看守路线,则该路线上的至少一个点可以看到 P 内的每个点。我们提出了一种增量算法,可以在 O(n3) 时间内为具有 n 条边的简单多边形构造最短的看守路线。这改进了之前的 O(n4) 界限。
The problem of finding the shortest watchman route in a simple polygon P through a point s on its boundary is considered. A route is a watchman route if every point inside P can be seen from at least one point along the route. We present an incremental algorithm that constructs the shortest watchman route in O(n3) time for a simple polygon with n edges. This improves the previous O(n4) bound.
