The 3D Bin Packing problem is a classic combinatorial optimization problem that has wide applications in logistics, warehousing, transportation, and many other fields. Its core is to reasonably pack a series of three-dimensional items (boxes) of various sizes into a limited number of three-dimensional containers (boxes, cargo containers, etc.), with the typical goal of minimizing the number of containers used or maximizing the utilization rate of containers while satisfying various constraints.
