Triangulating a simple polygon in linear time
B Chazelle - Discrete & Computational Geometry, 1991 - Springer
We give a deterministic algorithm for triangulating a simple polygon in linear time. The basic
strategy is to build a coarse approximation of a triangulation in a bottom-up phase and then …

Approximate nearest neighbors and the fast Johnson-Lindenstrauss transform
N Ailon, B Chazelle - Proceedings of the thirty-eighth annual ACM …, 2006 - dl.acm.org
We introduce a new low-distortion embedding of l 2 d into l p O(log n) (p=1,2), called the
Fast-Johnson-Linden-strauss-Transform. The FJLT is faster than standard random projections …

The power of geometric duality
This paper uses a new formulation of the notion of duality that allows the unified treatment of
a number of geometric problems. In particular, we are able to apply our approach to solve …

An optimal algorithm for intersecting line segments in the plane
B Chazelle, H Edelsbrunner - Journal of the ACM (JACM), 1992 - dl.acm.org
The main contribution of this work is an O(n log n + k)-time algorithm for computing all k
intersections among n line segments in the plane. This time complexity is easily shown to be …

A theorem on polygon cutting with applications
B Chazelle - 23rd Annual Symposium on Foundations of …, 1982 - ieeexplore.ieee.org
Let P be a simple polygon with N vertices, each being assigned a weight ∈ {0,1}, and let C,
the weight of P, be the added weight of all vertices. We prove that it is possible, in O(N) time, …

The Discrepancy Method: (Invited Presentation)
B Chazelle - International Symposium on Algorithms and …, 1998 - Springer
Discrepancy theory is the study of irregularities of distributions. A typical question is: given a
“complicated” distribution, find a “simple” one that approximates it well. As it turns out, many …

Givenn hyperplanes inE d , a (1/r)-cutting is a collection of simplices with disjoint interiors,
which together coverE d and such that the interior of each simplex intersects at mostn/r …
