Packing problems refer to a class of optimization challenges where the goal is to arrange objects within a defined space efficiently. These problems often arise in logistics, shipping, and storage, where maximizing space utilization is crucial. Common examples include fitting boxes into a container or arranging items on a shelf. These problems can be mathematically complex, involving various constraints such as size, shape, and weight of the items. Solutions often require algorithms or heuristics to find the best arrangement, making them relevant in fields like computer science, operations research, and industrial engineering.
