Python calculates the area of a plane point set
In today’s data-driven world, calculating the minimum circumscribed contour area of a plane point set is widely used in various practical scenarios. It is an important and fascinating task that aims to find a smallest rectangular or polygonal region that completely surrounds a given set of discrete points. This seemingly simple problem hides many challenges […]
