In computational geometry, the gift wrapping algorithm is an algorithm for computing the convex hull of a given set of points. In the two-dimensional case the algorithm is also known as Jarvis march, after R. A. Jarvis, who published it in 1973; it has O(nh) time complexity, where n is the number of points and … See more For the sake of simplicity, the description below assumes that the points are in general position, i.e., no three points are collinear. The algorithm may be easily modified to deal with collinearity, including the choice whether … See more • Convex hull algorithms See more The inner loop checks every point in the set S, and the outer loop repeats for each point on the hull. Hence the total run time is $${\displaystyle O(nh)}$$. The run time depends on the size of the output, so Jarvis's march is an output-sensitive algorithm See more WebMar 12, 2013 · As the wikipedia pseudocode does, you can keep one angle (the leftmost so far) in memory and compare against that.
