Abstract

An O(n3) algorithm is described to count triangulations of a simple polygon with nvertices. This algorithm is used to construct an O(n4) algorithm to generate triangulations of a simple polygon at random with a uniform probability distribution. The problem of counting triangulations of a simple polygon is then related to existing problems in graph theory.
