Packing problems are a class of optimization problems in mathematics that involve attempting to pack objects together into containers. The goal is to either pack a single container as densely as possible or pack all objects using as few containers as possible. Many of these problems can be related to real-life packaging, storage and transportation issues. Each packing problem has a dual covering … WebFeb 1, 2024 · Compared with cylindrical particle packing, the optimal AR of spherocylinders for maximum packing density is around 0.5. And for the elongated spherocylinders (AR > 1), the packing densities are lower than those of cylinders with the same AR.
