#include <CGAL/Polygon_convex_decomposition_2.h>
The Greene_convex_decomposition_2 class implements the approximation algorithm of Greene for the decomposition of an input polygon into convex sub-polygons [6].
This algorithm takes \(O(n \log n)\) time and \(O(n)\) space, where \( n\) is the size of the input polygon, and outputs a decomposition whose size is guaranteed to be no more than four times the size of the optimal decomposition.
| Kernel | must be a geometric kernel that can be used for the polygon. |
| Container | must be a container that can be used for the polygon. It is by default std::vector<typename Kernel::Point_2>. |
