摘要: We define the zigzag path of a pseudo-triangulation, concept generalizing triangulation point set. The pseudo-triangulation allows us to use divide-and-conquer type approaches for suitable (i.e., decomposable) problems on pseudo-triangulations. For this we provide an algorithm that enumerates all paths (of pseudo-triangulations given set with respect line) in O(n 2) time per and space, where n is number points. illustrate applications our scheme which include novel count
