Presentation Transcript


1. Andrew's Monotone Chain Convex Hull Algorithm

2. Andrew's Monotone Chain Scan A left-to-right variant of Graham's scan Discovered by Andrew in 1979 Using a linear lexigraphic sort of the point set by the x- and y-coordinates This may be an advantage if this order is already known for a set which is often the case.

4. The Chain Method Definition : A chain C = ( u1, … , up ) is a planar straight-line graph with vertex set { u1, … , up } and edge set { (ui, ui+1) : i = 1, …, p-1 }

5. The Monotone Chain Definition : A chain C = ( u1, …, up ) is said to be monotone with respect to a straight line L if a line orthogonal to L intersects C in exactly one point.
