Webb9 juni 2024 · Randomized incremental construction (RIC) is one of the most important paradigms for building geometric data structures. Clarkson and Shor developed a general theory that led to numerous algorithms that are both simple and efficient in theory and in practice. Randomized incremental constructions are most of the time space and time … Webb1 sep. 2015 · Although CDT construction by incremental segment insertion does not run in O (n log n) time, it is popular for good reasons: it takes advantage of the best existing implementations of (unconstrained) Delaunay triangulation algorithms; it is easier to implement than other CDT construction algorithms; its speed is often excellent in …

WebbGeom., 4 (1989), pp. 387–421]. A few extensions of the technique, obtaining efficient randomized incremental algorithms for constructing the entire arrangement of a collection of line segments and for computing a single face in … Webbare created during the randomized incremental construction ofDT(P). Experiments show that our approach is signi cantly faster than existing implementations if q has high degree, and competitive if q has low degree. 1 Introduction Some geometric applications require the ability to delete a vertex from a Delau-nay triangulation. nsf stefia cropped tee
