 ==================================================================
 
+Objective : To know implementation of different Computational Geometry algorithms for solving the Art-Gallery Problem. 
+
+Usage 
+=======
+
+ - Enter the number of random vertices in the top toolbar.
+ - Progress sequentially in the following order: 
+   Random Points -> Generate Polygon -> Trapezoidalize -> Monotone Partition -> Triangulation -> Dual Graph -> Three Coloring
