Minimum-weight triangulation of a convex polygon
A triangulation of a convex polygon results in a set of non-intersecting diagonals between non-adjacent vertices, which completely partition the interior of the convex hull of the polygon into triangles. The minimum weight triangulation (MWT) Read more…
