(classic problem)

**Definition:**
Find the triangulation with the greatest overall minimum angle. There is an incremental algorithm that takes *O(n log n)* time.

**See also**
*optimal polygon triangulation problem*.

*Note:
Triangulation is breaking up an area into triangles. The goal is to make all the triangles as close to equilateral as possible. Equivalently, have as few "slivers" as possible.
*

* This is the best triangulation if you want to interpolate a height field (topographic map) between given points, or to divide a surface to triangles and research the heat conduction, etc. between them. Contributed by Motty Porat (vn16908@netvision.net.il) 10 July 2000. *
