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 … WebThe problem is to select bins and assign the objects to bins so as to minimize the sum of bin costs while meeting the two resource constraints.
