Such a subdivision is not necessarily unique, and there may be other criteria to be optimized in computing the triangulation. Simple polygon A triangulation Dual graph Fig. 1: Polygon triangulation. WebFeb 27, 2003 · We propose a new linear time algorithm to represent a planar graph. Based on a specific triangulation of the graph, our coding takes on average 5.03 bits per node, and 3.37 bits per node if the graph is maximal. We derive from this representation that the number of unlabeled planar graphs with n nodes is at most 2 n + O (log n ), where 5.007.
