Polygon triangulation in O (n log log n) time with simple data structures
Abstract: "We give a new O (n log log n)-time deterministic algorithm for triangulating simple n-vertex polygons, which avoids the use of complicated data structures. In addition, for polygons whose vertices have integer coordinates of polynomially bounded size, the algorithm can be modified to run in O (n log[superscript *] n) time. The major new techniques employed are the efficient location of horizontal visibility edges that partition the interior of the polygon into regions of approximately equal size, and a linear-time algorithm for obtaining the horizontal visibility partition of a subchain of a polygonal chain, from the horizontal visibilty partition of the entire chain.
