Melkman的凸包算法 We describe an algorithm, due to Melkman (and based on work by many others), which computes the convex hull of a simple polygonal chain (or simple polygon) in linear time.

To accurately render a two-dimensional image of a three-dimensional scene, global illumination information that affects the intensity of each pixel of the image must be known at the time the intensity is calculated. In a simplified form, this inform

The two-guard problem asks whether two guards can walk to detect an unpredictable, moving target in a polygonal region P. no matter how fast the target moves, and if so, construct a walk schedule of the guards. For safety, two guards are required to
