WebDivide & Conquer. This alogrithm works by dividing the set of inputs into smaller and smaller inputs until the convex hull of that small input is easily calculated. Once that is complete, the alogrithm goes on to find the upper and lower tangents of the two newly found convex hulls, and uses the tangents to merge the two convex hulls together ... Web14 dec. 2016 · The most important part of the algorithm is merging the two convex hulls that you have computed from previous recursive calls. This part involves finding the lower and upper tangents of the two convex hulls and then proceeding with the merging. Web16 dec. 2024 · Animation depicting the Monotone convex hull algorithm. Andrew's monotone chain convex hull algorithm constructs the convex hull of a set of 2-dimensional points in (⁡) time..
