The is defined to be: ρ(x, d) = (x minimization diagram (appears above − c)2 r2. Voronoi Diagram using Divide-and-Conquer Paradigm . Shamos and Hoey [1] presented the first O(nlogn) deterministic algorithm for computing the Voronoi diagram in the plane that is optimal is a worst­case sense. This algorithm is significant from a theoretical standpoint not only because it was the first one but also it uses the divide-and-conquer paradigm. 交わる線分の集合Dを,効 率的な1次 元の探索データ 構造を用いて表現しておけば,上 記のShamos-Hoey の算法は,O(nlogn)の 手間で交差判定を実行する. 交差線分対を列挙するためには,線 分対の交点でも 走査線を一時停止することにする.線 分の上下関係が Shamos-Hoey Line segment intersection runtime.
