Abstract

Given a simple n-sided polygon, the triangulation problem is to partition the interior of the polygon into n — 2 triangles by adding n — 3 nonintersecting diagonals. We propose an O(log n)-time algorithm for triangulating monotone n-sided polygons using only n/log n processors in the CREW-PRAM model. This improves on the previously best bound of O(log n) time using n processors.
