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.

An in-place algorithm is one in which the output is given in the same location as the input and only a small amount of additional memory is used by the algorithm. In this paper we describe three in-place algorithms for computing the convex hull of a
