Paper Title
An Introductory Study on Art Gallery Theorems and Problems

In computational geometry and robot motion planning, a visibility graph is a graph of intervisible locations, typically for a set of points and obstacles in the Euclidean plane. Visibility graphs may also be used to calculate the placement of radio antennas, or as a tool used within architecture and urban planningthrough visibility graph analysis. This is a brief survey on the visibility graphs application in Art Gallery Problems and Theorems. Keywords- Art galley theorems, orthogonal polygon, triangulation, Visibility graphs
