The difficulty with developing incremental algorithms for these problems is that the introduction of a new circle or parabola can cause Theta(n) structural changes, leading to Theta(n^2) total structural changes during the running of the algorithm. In this note we examine the geometry of these ...
Finally an optimal linear algorithm both in average and worst-case and using a minimal space complexity in O(sqrt(N)) in average (or O(1) if in-place computation is allowed) is presented.doi:10.48550/arXiv.1304.2676Jean SouvironJ. Souviron, "Convex hull: Incremental Variations on the Akl...

incrementalalgorithms with a small number of dependences between iterations, such as randomized incremental constructions. In this paper we focus on the convex hull problem.Using our speculative engine, the algorithm can be automatically parallelized,with only a tiny fraction of the e,ort needed to ...

We present a simple algorithm for maintaining order-k Voronoi diagrams in the plane. By using a duality transform that is of interest in its own right, we show that the insertion or deletion of a site involves little more than the construction of a single convex hull in three-space. In ...

We present an algorithm for maintaining the width of a planar point set dynamically, as points are inserted or deleted. Our algorithm takes time O(kn) per update, where k is the amount of change the update causes in the convex hull, n is the number of points in the set, and >0 is...
