WebFeb 15, 2024 · We have discussed following algorithms for Convex Hull problem. Convex Hull Set 1 (Jarvis’s Algorithm or Wrapping) Convex Hull Set 2 (Graham Scan) The QuickHull algorithm is a Divide and Conquer …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 it should report only extreme points (vertices of the convex hull) or all points that lie on the convex hull . Also, the complete implementation must deal with degenerate cases when the convex hull has only 1 or 2 vertices, as well as with the issues of limited arithmet…
