Lower Bound for Sculpture Garden Problem
share
The purpose of the current study is to investigate a special case of art gallery problem, namely Sculpture Garden Problem. In the said problem, for a given polygon P, the ultimate goal is to place the minimum number of guards to define the interior polygon P by applying a monotone Boolean formula composed of the guards. As the findings indicate, the conjecture about the issue that in the worst case, n-2 guards are required to describe any n-gon (Eppstein et al. 2007) can be conclusively proved.
